The proposed research is intended to explain high resolution bioimaging problems addressed only phenomenologically before. A correct physical model would help the scientific community to optimise imaging of dynamic biological systems, extending our knowledge about the way living organisms function. With dynamic bioimaging, the mechanism of certain diseases such as Alzheimer's - where biomolecule fiber formation plays a key role - can also be addressed, thus the project has even therapeutical relevance. Furthermore, adequate description of liquid phase imaging can help engineers in the design of better hardware and software solutions, for the benefit of the bio-nanotechnological industry.Read moreRead less

Each of the spectrometers to be installed has significantly higher sensitivity and resolution than any other facility available in Australia and is capable of full spectrum imaging. This new spectroscopic infrastructure will enable the knowledge-based development of new materials by allowing complete characterisation of structure-composition-property relationships at the nanometre level.Read moreRead less

One in four people above 25 years suffer from diabetes-related diseases in Australia, with an associated economic cost exceeding $3 billion a year. A microdevice for continuous glucose monitoring would help patients to manage the disease, leading to huge individual, clinical and societal benefits. Life expectancy is expected to increase along with quality of life. Integration of the microdevice with insulin delivery would realise an 'artificial pancreas', revolutionising the management and treatment of the disease. The technology will also provide a platform for other point-of-care medical diagnostic devices, which will allow early participation in this emerging market and cement Australia's position in bionanotechnology.Read moreRead less

Novel research based around the Atomic Force Microscope are pursued to make ultra-sensitive measurement of forces between emulsion droplets and probe the mechanical properties of long molecules such as DNA. These studies generate basic knowledge that provides insight about emulsion stability that are of importance from the food and pharmaceutical industries to manufacturing drilling mud for oil wells.

This project will develop a robust technique for the quantitative real-time imaging of high-temperature superconductors. The image-analysis algorithm so obtained will be a virtual software lens, which is able to decode the information contained in data obtained by a well-established but hitherto qualitative imaging technique. We will transform this technique into one uniquely capable of obtaining two-dimensional movies of the current distributions, magnetic fields, and pinning defects in superconducting films. Such a quantitative characterization of these key superconductor parameters will be an important tool in the present global quest for room-temperature superconductivity.Read moreRead less
