Novel imaging technologies for continuous measurement of tracer kinetics in awake animals. The fates of biologically relevant molecules, such as proteins and antibodies, in the body are fundamentally important for understanding the mechanisms and treatment of disease. This project will enable for the first time continuous imaging of the location and time course of labelled molecules in conscious, freely moving animals.
Analysis, Optimization, and Control of Scanning Atomic Force Microscope Micro-Cantilever Probes. Atomic Force Microscopes (AFM's) are widely used for the examination of samples smaller than can be observed with an optical microscope. A tiny 'finger', only a few atoms wide at its sharpest point, is used to 'feel' the surface of a sample. This project aims to increase the resolution of AFM images by actively controlling the sensor probe dynamics.
Better quality AFM images would allow scientists ....Analysis, Optimization, and Control of Scanning Atomic Force Microscope Micro-Cantilever Probes. Atomic Force Microscopes (AFM's) are widely used for the examination of samples smaller than can be observed with an optical microscope. A tiny 'finger', only a few atoms wide at its sharpest point, is used to 'feel' the surface of a sample. This project aims to increase the resolution of AFM images by actively controlling the sensor probe dynamics.
Better quality AFM images would allow scientists to further investigate the atomic and molecular structure of such samples as: metals, polymers, cells, and proteins.
This research will contribute to the design of an Australian made Scanning Probe Microscope. Development of local expertise will provide a valuable resource for Australian scientific and industrial research.

Simultaneous measurement of brain function and behaviour in fully conscious laboratory animals. MicroPET is an advanced imaging technology that measures important biochemical processes, such as enzyme activity rates and receptor binding, in the living rodent brain. However, the requirement for the animal to be anaesthetised precludes the study of behavioural changes in response to sensory or drug stimulus during the imaging study. In this research, we will develop novel motion tracking and compu ....Simultaneous measurement of brain function and behaviour in fully conscious laboratory animals. MicroPET is an advanced imaging technology that measures important biochemical processes, such as enzyme activity rates and receptor binding, in the living rodent brain. However, the requirement for the animal to be anaesthetised precludes the study of behavioural changes in response to sensory or drug stimulus during the imaging study. In this research, we will develop novel motion tracking and computational algorithms that enable microPET to non-invasively image the brains of conscious, freely moving animals while simultaneously observing their behaviour. These new technologies will, for the first time, allow neuroscientists to study the genetic, behavioural and neurochemical correlates of brain disease.Read moreRead less
