BioMagnetics research group

The BioMagnetics Group investigates the role of physics and magnetism in biology and medicine and works to develop magnetic and nano-based technologies for biomedical applications. We are a dynamic, interdisciplinary research group, equipped with state of the art magnetic measurement facilities and a modern wet lab.

Our research

Under the guidance of Professor Tim St Pierre, the members of the group work on a diverse range of topics including iron-overload disorders, magnetic nanoparticles and magnetotactic bacteria. In recent years an increasing level of international interest within the field has resulted in collaborations with institutions both within Australia and overseas. With this continued growth it it seems likely that there will be a bright and exciting future ahead for research within this field.

The BioMagnetics Research Group carries out research on naturally occurring magnetic materials in biological systems and on the development of novel physical methods for their characterization, measurement, detection, and imaging. The Group also is developing magnetic nanoparticle systems and complementary instrumentation for biomedical and medical applications.

Projects

The BioMagnetics Group undertakes a variety of research programs from pure basic research to experimental and commercial development.  Some examples of our research projects are listed below. 

Pure Basic Research

Small Particle Magnetism

As magnetic particles become small, approaching 10 nm, a number of changes occur to the properties these materials exhibit in bulk form. There are changes to coercivity mechanisms, magnetisation values and their time dependent properties.  New properties such as superparamagnetism appear and it is possible to observe dipolar and exchange interactions within and between particles.  The BioMagnetics group undertakes a range of research into small particle magnetism to better understand how the structure of the particles leads to different magnetic properties. 

Biomineralisation

Iron is critical to nearly all forms of life, but it can catalyse damaging free radical reactions in its free form.  Soluble iron is also relatively scarce in the environment and so living things must develop ways to capture and safely store iron.  In animals, iron is stored as an iron oxyhydroxide complex within a protein cage called ferritin. The BioMagnetics Group conducts research into how different animals store and use iron in the body.  Some of the examples of iron biomineralisation we have studied include marine molluscs (chitons and limpets), which use iron oxides as a hard cutting edge for their teeth, while magnetotactic bacteria use magnetite crystals to provide a sense of direction that gives them an evolutionary advantage over their competitors.  

Magneto-reception

It has been shown that a number of animals possess the ability to navigate using the earth’s magnetic field.  In order to do so, these animals must have the ability to sense the strength and/or direction of the local magnetic field.  A number of potential magneto-receptors have been postulated, but conclusive proof of their existence has not yet been shown.  We work with biologists and microscopists in trying to detect and identify magneto-receptors based on iron based particles and compounds.  

Strategic Basic Research

Development of MRI contrast agents

In order to improve the effectiveness of medical imaging, or to enhance the visualization of specific components in a living body, it is often necessary to administer chemical compounds, known as contrast agents or media, so that the contrast between different tissues (e.g. healthy against diseased) can be increased.  The BioMagnetics Group works on the development and characterisation of novel contrast agents based on superparamagnetic nanoparticles of iron oxide coated with polymer surfactants to improve the biocompatibility and provide targeted biodistribution.

Magnetically targeted and activated drug delivery

One of the most exciting goals in nanotechnology research is the development of techniques for the delivery of drugs to a specific target and the release of those drugs through an activation signal.  Magnetic nanocomposites provide a potential vehicle to achieve both these goals.   Magnetic particles can be moved by the application of magnetic fields and field gradients through a process known as magnetophoretic motion. In addition, if exposed to an alternating magnetic field the energy released from the magnetic particles can be sufficient to change the magnetic nanocomposite and release an encapsulated drug.  We are interested in understanding the mechanisms of both magnetophoresis and activated drug release in order to design better nanocomposites and  the equipment to both target and release drugs.

Pathogenic iron deposits

The human body has no efficient mechanism to excrete iron and hence iron levels in the body are largely maintained by control of iron absorption from the diet.  However, if the control of iron absorption is defective or if iron is directly administered through supplements or ongoing blood transfusions, then iron levels can increase beyond the limit of the body’s natural iron storage mechanisms.  If this happens then it is possible that the excess iron can be deposited in the body in pathogenic forms leading to a range of negative effects.  The BioMagnetics Group is interested in understanding the formation and deposition of pathogenic iron deposits their quantitative determination and methods for their removal.

Applied Research

Development of new diagnostic techniques for Schistosomiasis

Schistosoma parasites damage organs, impair growth and cause neural disease among their hosts. Diagnosis of an infection is typically by screening the faeces of the infected person for the eggs of the parasite. The eggs are formed by an interesting biomineralisation process which lends itself to magnetic detection and characterisation. 

Liver fat determination using MRI

Around 50% of colorectal cancer (CRC) patients develop secondary cancers, typically in the liver. Liver surgery is the treatment of choice, but chemotherapy that is often administered prior to surgery can lead to the development of fatty liver.  Patients with moderate to high levels of liver fat having major liver surgery have an increased risk of death (up to 3 times), more post-operative complications of greater severity and hospital costs up to 70% higher compared to patients with normal levels of liver fat. A reliable liver fat measurement for screening liver resection patients would lead to better-informed surgical planning decisions that could result in more patients becoming eligible for surgery and potentially reduce the rate of post-operative complications and associated costs.  Our group has recently developed a highly sensitive and specific, non-invasive, MRI-based approach for measuring liver fat (FDA approval received December 2013) and is researching the application of this technique prior to liver surgery.  

Experimental Development

FerriScan® - Iron determination in hemoglobinopathies 

The BioMagnetics Group is a pioneer in the non-invasive measurement of liver iron concentrations by magnetic resonance imaging (MRI). Present techniques for quantifying tissue iron by MRI rely on the paramagnetic character of the iron stores. The pioneering work of this group led to a non-invasive liver iron measurement technique that is now commercially available through Resonance Health Ltd and is marketed as FerriScan®. Research has progressed to include other iron loaded organs, such as the spleen, heart and brain.  

Malaria detection using magnetic fractionation

When a malaria parasite feeds on and digests haemoglobin it produces an iron based waste product called hemozoin. Although only weakly magnetic, the hemozoin makes late stage parasites sufficiently magnetic that they can be magnetically separated from blood using a technique known as magnetic fractionation.  We have shown that magnetic fractionation can be used as a highly sensitive and specific diagnostic technique for the presence of gametocytes, the form of the malaria parasite that circulate in the blood and responsible for the transmission of the disease.  This technique has similar sensitivity to DNA based techniques, but at a fraction of their cost and can be easily carried out in the field with minimal laboratory equipment.   The technique is presently undergoing field trials in Papua New Guinea as part of an assessment of different drug therapies.

In addition, the EQD group was invited to be a member of the European consortium ULiSSE, which is designing and developing new detector technology for novel experiments at the FERMI Free Electron Laser Source.

Field Theory and Quantum Gravity Research Group

This research group's focus is on various aspects of supergravity, supersymmetric quantum field theory and string theory.

Unification of gravity with the other fundamental interactions within a consistent quantum theory is one of the central problems of high-energy physics. The complete structure of such a theory is not yet known despite numerous efforts undertaken over several decades to construct it. The most interesting models for quantum gravity include string theory and its low-energy approximations known as supersymmetric theories of gravity or supergravity.

Research activities

The group's research activities include:

  • Effective actions in gauge theories and quantum gravity.
  • Supergravity-matter systems in diverse dimensions.
  • Superconformal field theories.
  • String theory and its applications to particle physics.

Frequency and Quantum Metrology Research Group

We aim to build instruments with world-class precision and performance that we can use to make measurements of high value and interest in both fundamental physics and more practical applications.

Many modern developments in today's society are based on high-quality clocks and oscillators: the Global Positioning System (GPS) satellite system, radar, optical fibre communications, even mobile phones. The group's goal is to develop new frequency standards and technologies with two endpoints in mind: to improve systems that are based on high-quality clocks and oscillators (such as those listed above), and to use these as precision tools to test the foundations of physics.

We are dedicated to commercialising our inventions and thus hold patents in conjunction with industry. Our research programs include strong international and industrial collaborations.

Our group undertakes research projects that cover a broad spectrum of interests, ranging from engineering to fundamental physics. Some of our projects include:

  • Quantum Metrology within the ARC Centre of Excellence for Engineered Quantum Systems (EQuS).
  • Advancing the Cryogenic Sapphire Oscillator – one of the world’s most stable frequency sources.
  • The Ytterbium Lattice Clock.
  • Space applications: Ground Station for the European Space Agency's ACES mission.
  • Low noise frequency and phase synthesis and measurement techniques.
  • Testing Lorentz invariance by measuring speed of light isotropy, in collaboration with Humboldt University of Berlin.
  • Measurement of electronic and magnetic properties of materials.
  • Novel high-Q microwave and millimetre wave resonators.
  • Laboratory based searches for Weakly Interacting Slim Particles.

 

Yb Lattice Clock

A ground based Yb lattice clock for participation in future space-clock missions.

Industry, defence and commerce all depend on accurate time keeping, and as clock technologies have improved they have unveiled capabilities such as the global positioning system (GPS) and very long baseline interferometry (VLBI). Atomic clocks have been at the forefront of physics for several decades and now they probe nature’s behaviour at the most fundamental level — in ways comparable in significance to high energy collider experiments, by searching for temporal changes in fundamental constants. Rather than rely on extraordinarily high energies, atomic spectroscopy relies on extraordinary levels of precision. The improvement in accuracy of clocks is advancing at approximately a factor of 500 per decade (compared to ~13 for Moore’s law). This rapid scientific advance suggests a certain inevitability with regard to finding new phenomena.

Recent measurements in various laboratories have shown astonishingly high accuracy for a number of different clock transition frequencies and ratios. These clocks are isolated in separate laboratories around the globe, thus the means to compare the clocks is heavily sought. With future space-clock missions such as the Atomic Clock Ensemble in Space  (ACES) mission and possible future missions, such as Space Optical Clock (SOC) and STE-QuEST (Space-Time Explorer and Quantum Equivalence Principle Space Test), a much greater opportunity will be granted for frequency comparisons between clocks distributed around the earth.

At UWA we are developing an optical lattice clock based on a particular electronic transition in 171Yb, with the aim of participating in future space-clock missions. Such clocks  have already demonstrated outstanding performance (e.g. at NIST, NMIJ, RIKEN & KRISS). The 171Yb ‘clock’ transition is included in the CIPM’s  (Comité International des Poids et Mesures) list of secondary representations of the second.  

 

Progress on the Yb lattice clock

The UWA atomic clock was first put into operation after 2.5 years of development (the first of its kind in the southern hemisphere). By comparison with a hydrogen-maser, its accuracy is in the parts per trillion range.

The experiment has also accomplished the following.
  1. A dual-wavelength magneto-optical trap (MOT) has been installed that laser cools and traps neutral ytterbium atoms. The device uses unconventional laser wavelengths at 399nm and 556nm. Both require moderately complex schemes for their generation. The temperatures achieved in the dual-wavelength MOT are 20 μK for (171)Yb (fermionic) and 40 μK  for (172)Yb (bosonic). We use a new, cost effective, means of generating the 556nm radiation.
  2. The absolute frequency of the 1S0-3P1(F’=3/2) inter-combination line in 171Yb has been measured to be 539390406833 ±310 kHz. The frequency separation between this line and the clock transition is found to be 21094570280 ± 36 (stat.) ±310 (syst.) kHz.
  3. An inverted crossover resonance has been observed in saturated absorption spectroscopy of 171Yb for the first time. This may also be the first occasion where the effect has been seen in a group II atom. We have used the signal to stablize the frequency of 556nm light needed for laser cooling of 171Yb and demonstrated a temperature of 20 μK.
  4. A frequency comb has been generated to cover the relevant wavelengths of the (lattice) clock; for example: 1156nm, 1112nm and 759nm. The mode-locked laser light from a master oscillator (centred at 1550nm) has been amplified and coupled into a section of highly nonlinear fibre (high step index) to extend the wavelength range to below 1100nm. The frequency comb mode spacing is steered by a hydrogen maser.
  5. An ultra-stable laser at 1156nm has been set up, including a 4×105 finesse optical cavity inside a vacuum chamber with surrounding thermal shields.  This laser, when frequency doubled, probes the clock transition in the Yb atoms (at 578.4nm).  The drift rate of the laser is presently 60mHz/s  (4×10-16 s-1), and steadily falling.  We perform the clock transition spectroscopy with a Rabi frequency of ~6kHz.

Laboratory Searches for Weakly Interacting Slim Particles

Many attempts to expand the Standard Model of particle physics via string theories or supersymmetry theories inevitably predict the existence of new particles that we have yet to observe. One such family of these hypothetical particles are the Weakly Interacting Slim Particles, or WISPs. As the name suggests, not only do WISPs interact very weakly with standard matter but they also have extremely small masses of less than 1 electronvolt. For comparison, a proton has a mass on the order of one billion electronvolts. What this means is that on an intrinsic level WISPs are remarkably difficult to detect and measure. It is these same properties that also allow WISPs to be formulated as compelling dark matter candidates.

The primary focus of our work is designing and performing experiments to search for a type of WISP known as the Hidden Sector Photon, or Paraphoton. This particle is coupled very weakly to the standard photon and does not interact with standard matter. We aim to constrain the strength of this photon / paraphoton coupling as a function of paraphoton mass.

One of our main experiments is known as a “Light Shining Through a Wall” experiment. Photons are generated on one side of an impenetrable barrier; in order to cross this partition the photon would need to convert to a paraphoton and pass through. By searching for photons on the other side of the barrier we can attempt to detect photon to paraphoton to photon conversion events. In order to reduce the level of background noise present in the detector the experiment is performed at cryogenic temperatures (approximately -270 C). As usual, we employ a variety of experimental tricks to enhance the sensitivity of our experiment and we are always applying the advances in measurement techniques we develop to other areas of research.

Gravitational Wave Astronomy

With the first gravitational wave signal detected in 2015, gravitational wave astronomy emerges as a new branch of astronomy that involves both detecting gravitational waves and using gravitational wave observations to advance our understanding of the Universe.

Ground-based laser interferometers aim to detect gravitational waves in the audio frequency band, from 10 Hz to several kHz. The Laser Interferometer Gravitational Wave Observatory (LIGO) in the United States made the first two detections of gravitational wave signals from coalescing binary black holes in 2015. On the other front, pulsar timing arrays exploit the exceptional rotational stability of millisecond pulsars in order to detect nanohertz gravitational waves. The first detection in the nanohertz gravitational waves is likely to happen within the next decade.

Our group is part of the LIGO Scientific Collaboration, which consists of more than 1000 scientists who have joined force to search for gravitational waves. We are leading one of the online detection pipelines for gravitational waves from coalescing binaries of black holes and neutron stars using LIGO data. Our group was actively searching for gravitational waves when the first two signals were detected in 2015 and will continue to be actively involved in gravitational wave searches in future science runs of LIGO as well as the Virgo detector in Europe.

Our group is also a Tier-1 member of the Australia-based Parkes Pulsar Timing Array (PPTA) collaboration and is actively involved in using Parkes pulsar timing data to search for gravitational waves from binaries of supermassive black holes. We are also part of the International Pulsar Timing Array collaboration, formed by PPTA and its international counterparts in Europe and North America.

Research activities

Our group’s ongoing research activities include:

  • Real-time detection of audio-band gravitational waves from binary coalescences of black holes and neutron stars
  • Acceleration of the detection pipelines using high-performance supercomputing technologies including the use of Graphics Processing Units (GPUs)
  • Astrophysics of gravitational wave sources and electromagnetic follow-up observations 
  • Searching for gravitational waves from individual supermassive black hole binaries using Parkes Pulsar Timing Array data
  • Investigating the potential of future large radio telescopes including FAST and pathfinders for the Square Kilometer Array (SKA) in detecting gravitational waves and studying the formation and co-evolution of galaxies and supermassive black holes

PhD Opportunities

We are looking for highly motivated applicants with interest in gravitational wave data analysis and multi-messenger astronomy including gravitational waves.  Background with physics, astronomy and related disciplines is desirable. Experience with high-performance computing is a plus.

The prospect student will work on two broad areas of gravitational wave detection:

  • Detecting gravitational waves from coalescing binaries of neutron stars and black holes with ground-based interferometers
  • Detecting nanohertz gravitational waves with pulsar timing arrays.

Spintronics and Magnetisation Dynamics Research Group

Our research focus is on magnetic materials. We are interested in microwave, magneto-optical, spintronic and left-handed properties of ferro-, ferri- and anti-ferromagnetic thin films, multilayers and nanostructures.

Such materials are highly promising candidates for a new generation of smaller, faster and energy efficient electronics for communications, data processing and storage, and for field-, substance- and bio-sensing. 

The group is strong in both experiment and theory. Extensive and close co-operation between experimentalists and theoreticians within the group ensures the highest degree of research quality and completeness.

Our experimental research relies on the most advanced methods of fabrication and characterisation of magnetic materials and nanostructures. A number of experimental methods and technologies used in our research are unique in Australia. Among them are nanostructuring of magnetic films and multilayers, fabrication of microscopic microwave components, magneto-optical and SQUID magnetometry,  spin-transfer torque microwave nano-oscillator technology, magneto-optical imaging, quasi-static measurements of domain wall dynamics, broadband and cavity-based ferromagnetic resonance and traveling spin wave spectroscopy.

Theoretically we are strong in both analytical and computational methods of describing the physics of magnetic materials as well as the physics of waves and oscillations in general, including non-linear waves, solitons, wave instabilities and chaos.

Terahertz research group

The Terahertz and Optical Technology research group is involved with developing and applying new technologies to a number of biomedical and other applications.

Our main focus is on terahertz imaging and spectroscopy.

What is Terahertz?

The Terahertz (THz) or submillimeter region of the electromagnetic spectrum lies on the border of where we perceive electronics and optics to meet. This 'borderline status' is one reason why these frequencies (0.1-10 THz) had been difficult to produce until relatively recently.

Microwaves are generated by using high-speed oscillating devices, while infrared is generated thermally or by other light sources. Infrared sources become very dim as we approach the THz region. However, the advances in femtosecond lasers have facilitated the convenient generation of short bursts of THz, opening up a new part of the spectrum for study.

In the late 1980s the first coherent pulses of THz had been demonstrated, but the field did not take off until the late 1990s when THz time domain spectroscopy and imaging was introduced. Now there is a large and still increasing number of research groups around the world working in this field and some commercial companies producing THz systems with applications in non-destructive testing, pharmaceutical science, chemistry, physics and biology.

Some of the key projects we are working on

  • Theoretical modelling of the interaction of terahertz radiation with biologic tissue
  • Modulation of Neurons with THz light
  • Assessment of Burns and Scars
  • Multi-modal imaging for improved cancer detection
  • Development of an Intra-Operative Tool for Tumour Margin Assessment During Surgery

Zadko Telescope

The Zadko Telescope is a one-metre telescope funded by a generous donation from James Zadko to UWA.

The telescope has opened a new window to the “transient universe” - a universe that is filled with fleeting flashes of light originating from the most exotic phenomena in the cosmos.

The telescope is located in a purpose-built observatory, close to the UWA gravitational research facility about 70 kilometres north of Perth.

It scans the sky for potentially hazardous asteroids, and is helping to inspire the next generation of scientists.

Zadko is an important facility for astronomy research at UWA, and is a joint resource for the UWA School of Physics.

Zadko is partially supported by the ARC Centre of Excellence Ozgrav.

Zadko collaborates with a number of international partners, including the following.
