The Network in Fluorescence applications in biotechnology and life sciences will coordinate a research program relating to applications of fluorescence whose proper resolution requires a high degree of interaction between biology, physics, chemistry, bioengineering and medicine. These would be applied to industrially relevant problems in areas such as public health, biotechnology, safety of foods, chemical biology and environmental monitoring. Approaches such as highly selective fluorescent labelling of targets using appropriate immunological and molecular techniques and purpose-engineered fluorochromes accompanied by the development of specialised instrumentation will capitalise on the multi-disciplinary research strengths in Australia and lead towards tangible industrial outcomes.

Probing Anaesthetic Effects with New Functional Imaging Paradigms. This project seeks new insights into the effects of anaesthetics on brain function and repair. Anaesthesia is used in small-animal imaging to immobilise the animal, but in many cases the anaesthesia itself affects the neurophysiological parameters under study. It has also been shown that many anaesthetics enhance recovery after brain injury in small animals. This project plans to exploit a novel functional brain-imaging technique ....Probing Anaesthetic Effects with New Functional Imaging Paradigms. This project seeks new insights into the effects of anaesthetics on brain function and repair. Anaesthesia is used in small-animal imaging to immobilise the animal, but in many cases the anaesthesia itself affects the neurophysiological parameters under study. It has also been shown that many anaesthetics enhance recovery after brain injury in small animals. This project plans to exploit a novel functional brain-imaging technique for conscious animals to gain new insights into the effects of anaesthetics on brain function and recovery from injury. The knowledge gained is expected to improve knowledge of anaesthetic action, guide future anaesthetic use in small animal imaging to improve the accuracy of image-derived research data, and help to clarify how anaesthetics confer neuroprotective effects in brain injury.Read moreRead less
The Surface Science of Vacuum Glazing. In order to achieve a stable vacuum in evacuated glazing, high temperature baking during evacuation is required. The high temperature processing prevents the use of strengthened glass, such as tempered glass. However, samples made at low temperatures suffer from poor vacuum characteristics, particularly when exposed to UV radiation. In this project, we aim to discover the chemical and physical processes occurring on the glass surface responsible for vacuum ....The Surface Science of Vacuum Glazing. In order to achieve a stable vacuum in evacuated glazing, high temperature baking during evacuation is required. The high temperature processing prevents the use of strengthened glass, such as tempered glass. However, samples made at low temperatures suffer from poor vacuum characteristics, particularly when exposed to UV radiation. In this project, we aim to discover the chemical and physical processes occurring on the glass surface responsible for vacuum degradation. We will use this knowledge to develop a low temperature manufacturing process that can be used with tempered glass and results in a high-quality vacuum, stable over the device service life.Read moreRead less
Pulsed oscillating mass analyser. Mass spectrometers are ubiquitous components in chemical analysis, but are often large and expensive. We have developed a new method for mass analysis, which is smaller and cheaper than existing technology. However, the analyser needs further research to determine whether it has the performance specifications to match the other technologies. The objective of this research is to characterise, explore and extend the prototype and to develop the appropriate math ....Pulsed oscillating mass analyser.

However, the analyser needs further research to determine whether it has the performance specifications to match the other technologies. The objective of this research is to characterise, explore and extend the prototype and to develop the appropriate mathematical algorithm for mass analysis. Success in this project may lead to a new mass analyser that can be incorporated into analytical instruments, many of which are manufactured in Australia.Read moreRead less
Realistic models of permeation in ion channels. Ion channels are formed by proteins in cell membranes and provide pathways for fast and controlled flow of selected ions. This activity generates action potentials in nerves and muscles that forms the basis of all movement, sensation and thought processes. Recent determination of the crystal structure of channel proteins has enabled construction of models that can relate channel function to its structure--necessary for understanding their operati ....Realistic models of permeation in ion channels. Ion channels are formed by proteins in cell membranes and provide pathways for fast and controlled flow of selected ions. This activity generates action potentials in nerves and muscles that forms the basis of all movement, sensation and thought processes. Recent determination of the crystal structure of channel proteins has enabled construction of models that can relate channel function to its structure--necessary for understanding their operation and seeking cures for diseases caused by their malfunction. This project aims to develop accurate ion-protein-water interactions for permeation models based on stochastic and molecular dynamics simulations using both classical and quantum mechanical methods.Read moreRead less

Summary
The forest and the trees: How global brain rhythms facilitate local information processing. One of the greatest challenges in understanding the brain is the enormous range of scales it operates on, from single neurons a few microns across to entire hemispheres on the scale of tens of centimetres. This project will investigate how large-scale brain rhythms influence and facilitate information processing, particularly motor control, among small networks of individual neurons. The research question ....The forest and the trees: How global brain rhythms facilitate local information processing. One of the greatest challenges in understanding the brain is the enormous range of scales it operates on, from single neurons a few microns across to entire hemispheres on the scale of tens of centimetres. This project will investigate how large-scale brain rhythms influence and facilitate information processing, particularly motor control, among small networks of individual neurons. The research questions will be addressed by combining detailed computer simulations with data-driven analyses of empirical human and monkey brain dynamics. The outcomes of this project will provide a richer understanding of how our brains encode and process information, leading to practical benefits such as improved control of artificial limbs.Read moreRead less
A rational approach to a high-resolution structure of the multidrug transporter EmrE. Membrane proteins form only 0.3% of the available protein structures in the protein data bank (PDB), yet 30% of the proteins in the human genome and 50% of human drug targets are membrane proteins. Multidrug transporters are membrane proteins responsible for antibiotic resistance in humans.

Membrane proteins form only 0.3% of the available protein structures in the protein data bank (PDB), yet 30% of the proteins in the human genome and 50% of human drug targets are membrane proteins. Multidrug transporters are membrane proteins responsible for antibiotic resistance in humans. A high-resolution structure of a multidrug resistance protein, together with comprehensive biochemical characterization, would enable a detailed understanding of how these protein functions. Potentially it could also aid in the development of specific inhibitors that would prevent EmrE (and perhaps other similar proteins) from carry out its harmful mission. Read moreRead less

Parametric Brain Imaging via Modeling and Analysis of Electroencephalographic Signals. Parameters of brain function and physiology will be spatially imaged with high time resolution via their effects on electroencephalographic (EEG) signals, a form of imaging that is impossible with existing methods.

This will be achieved by improving existing physiologically-based models of the generation of EEGs and developing analysis tools based on fitting of model predictions to multielectrode EEG data. The results will be used to probe spatiotemporal features of EEGs in normal subjects to explore the underlying fundamental mechanisms and to infer novel parameter variations of practical relevance.Read moreRead less
