Acoustic trapping for life science applications. Force fields can be established to move suspended cells into predefined locations using high frequency vibration; randomly dispersed cells can be brought together into clusters. This project aims to develop such technologies and will have applications in drug discovery and cell to cell interaction studies and has the future potential to promote the health of Australians.
Motion-adaptive PET technology for brain imaging of freely moving mice. This project aims to develop new brain imaging technology that adapts to and corrects for the motion of a responsive, freely moving mouse. Current technology requires the subject to be unconscious, precluding the use of imaging to study signalling pathways activated by external stimuli during cognitive and behavioural tasks. By harnessing new radiation detector, motion tracking and computational technologies, the project exp ....Motion-adaptive PET technology for brain imaging of freely moving mice. This project aims to develop new brain imaging technology that adapts to and corrects for the motion of a responsive, freely moving mouse. Current technology requires the subject to be unconscious, precluding the use of imaging to study signalling pathways activated by external stimuli during cognitive and behavioural tasks. By harnessing new radiation detector, motion tracking and computational technologies, the project expects to bridge this technology gap and provide significant technical and conceptual advances in the field. This will provide important benefits, such as equipping neuroscientists with new tools to answer fundamental questions about how the mammalian brain regulates behavioural adaptation to a changing environment.Read moreRead less
Next generation positron imaging technologies for contemporaneous measurements of brain function and behaviour in freely moving mice. The mouse brain is an important target for Post Emission Tomography (PET) imaging studies that aim to elucidate the role of specific molecular pathways in determining normal and aberrant brain function. However, current imaging technology requires the animal to be unconscious which precludes the study of pathways involved in cognition, learning and behaviour. To o ....Next generation positron imaging technologies for contemporaneous measurements of brain function and behaviour in freely moving mice. The mouse brain is an important target for Post Emission Tomography (PET) imaging studies that aim to elucidate the role of specific molecular pathways in determining normal and aberrant brain function. However, current imaging technology requires the animal to be unconscious which precludes the study of pathways involved in cognition, learning and behaviour. To overcome this major limitation this project will: investigate tomograph designs capable of continuously imaging a moving animal; develop a PET detector with sub-millimetre spatial resolution and depth-of-interaction capability; and, develop a fully integrated motion tracking system. This research will lead to next generation PET technologies for contemporaneous brain imaging and behavioural analysis in freely moving mice.Read moreRead less
Rotating Radiofrequency Phased-array for 7 Tesla Magnetic Resonance Imaging. This project aims to develop a new type of radiofrequency coil array to ensure high-field magnetic resonance imaging (MRI), with all its benefits, is available for a broader range of applications. High-field MRI offers faster scans with more detailed images than lower field systems. This enhanced sensitivity potentially enables smaller structures to be resolved in the body. At high fields, however, standard radiofrequen ....Rotating Radiofrequency Phased-array for 7 Tesla Magnetic Resonance Imaging. This project aims to develop a new type of radiofrequency coil array to ensure high-field magnetic resonance imaging (MRI), with all its benefits, is available for a broader range of applications. High-field MRI offers faster scans with more detailed images than lower field systems. This enhanced sensitivity potentially enables smaller structures to be resolved in the body. At high fields, however, standard radiofrequency coils, an essential component of MRI systems, can distort images and induce potentially harmful tissue heating. The aim is to design and develop a rotating multi-channel radiofrequency coil array, with dedicated image reconstruction software, to overcome these limitations. This would facilitate detailed images that can be obtained quickly and safely.Read moreRead less
Understanding surface acoustic wave atomisation for pulmonary delivery of drug aerosols in personalised medicine. Delivering drugs via the lung is hampered by development costs and inadequate technology. This project will provide an understanding of atomisation in our unique respire system, enabling not only the delivery of new vaccines and drugs but also the rapid and cost effective development of new disease treatments personalised to the patient.

A Multi-Optrode Array for Closed-Loop Bionics. We will design, implement and characterise a disruptive multi-channel optrode array (MOA) to record and stimulate excitable living tissue. The MOA will be a combination of individual optical electrodes (optrodes) that either comprise a new class of liquid crystals, used to passively sense extracellular biopotentials, or microphotovoltaic cells that will be used for electrical stimulation of excitable tissue.

The MOA will be a combination of individual optical electrodes (optrodes) that either comprise a new class of liquid crystals, used to passively sense extracellular biopotentials, or microphotovoltaic cells that will be used for electrical stimulation of excitable tissue. By employing light for communication with optrodes, this new approach alleviates many of the wiring, packaging and encapsulation issues associated with existing devices. Computational modelling and in vitro testing in cardiac tissue and retinal neurons will demonstrate the utility of the MOA to sense and control electrical activity.Read moreRead less
Design of an optrode for next generation brain-machine interfaces. The project plans to use a new class of liquid crystals – deformed helix ferroelectric (DHF) liquid crystal – to sense extracellular biopotentials. In response to an applied electrical field, it has been shown that DHF crystals can modulate a polarised light source with extraordinary sensitivity and linear response down to the microvolt range. Using this technology, the project plans to initially design and test a single optrode ....Design of an optrode for next generation brain-machine interfaces. The project plans to use a new class of liquid crystals – deformed helix ferroelectric (DHF) liquid crystal – to sense extracellular biopotentials. In response to an applied electrical field, it has been shown that DHF crystals can modulate a polarised light source with extraordinary sensitivity and linear response down to the microvolt range. Using this technology, the project plans to initially design and test a single optrode device on the bench, before in vitro testing and characterisation using two-photon microscopy. The final design would be a higher density sensor array using a fibre optic source and multiple optical couplers. This may support the development of new ways to implant sensing and diagnostic devices in the body.Read moreRead less
Dynamic Mechano-Microscopy for use in Mechanobiology . We will develop an innovative microscope that will enable new discoveries in biology. Most microscopes form images of a sample's optical properties, instead we will image a sample's mechanical properties. The reason our novel approach is needed is that cell behaviour depends on the stiffness of it's environment, but current microscopes are unable to image this.

The reason our novel approach is needed is that cell behaviour depends on the stiffness of it's environment, but current microscopes are unable to image this. Our microscope will provide insights in biology that can improve our understanding of cells, the building blocks of life. We will achieve this by: 1. Developing a microscope that combines microscopic resolution with rapid imaging; 2: Developing the capability to image both within the cell and its surrounding environment; and 3. Using our microscope to make discoveries in biology.Read moreRead less

The project will shrink an entire microscope to the size of an optical fibre – as thin as a single strand of hair – and image deep regions of the central nervous system. This is expected to improve diagnostic tools and the knowledge of degenerative brain diseases, including Alzheimer's disease and amyotrophic lateral sclerosis.
