Australia is strongly investing in nanotechnology and through the governments priority goals 'Frontier Technologies for Building and Transforming Australian Industries' it has been recognised as an important area for investment. This proposal will help develop an internationally recognised nano-industry. It is envisaged that the particles made during this work will have direct implications for the public - creating a new class of medical diagnostic particles with better resolution and specificity. These particles have the potential to diagnose patients more precisely and at an earlier stage than is currently available. Additionally, these particles could be designed to load drugs and hence could be used to treat diseases such as cancer.Read moreRead less
Efficient and tailored supercontinuum generation using dispersion management. Imagine a laser beam, but not with just one colour, but containing all colours. The light beam thus looks white, somewhat like a search light, except that it is much brighter. We now know how to generate such bright white beams of light, but it is expensive, requiring a small specialized laboratory full of equipment. Through a better understanding, we will make it easier and cheaper to generate these light beams. All k ....Efficient and tailored supercontinuum generation using dispersion management. Imagine a laser beam, but not with just one colour, but containing all colours. The light beam thus looks white, somewhat like a search light, except that it is much brighter. We now know how to generate such bright white beams of light, but it is expensive, requiring a small specialized laboratory full of equipment. Through a better understanding, we will make it easier and cheaper to generate these light beams. All kinds of applications that have been known for years, such as medical imaging and chemical analysis, then suddenly become practical. We anticipate that in the future these bright white light beams will be used on a routine basis in Australian hospitals and industry. Read moreRead less

Synchrotrons, wavelet analysis and novel imaging techniques - applying physics tools to the war against breast cancer. Breast cancer leads to the second highest number of person-years of life lost due to cancer in Australia, with little known about its transport around the body. Current screening methods for breast cancer are neither 100% sensitive or specific and are heavily dependent upon expert training.

Breast cancer leads to the second highest number of person-years of life lost due to cancer in Australia, with little known about its transport around the body. Current screening methods for breast cancer are neither 100% sensitive or specific and are heavily dependent upon expert training. This project will contribute by yielding valuable information on the transport of breast cancer and contribute to the development of an automated diagnostic method, with the possibility of its application to other diseases. The project will also involve members of the regional community, train regional scientists and provide synchrotron experience for Australian scientists in time for Australia's first synchrotron.Read moreRead less

Modelling and Measurement of Flow-Structure Dynamics in the Human Upper Airway. Sleep disruption due to the common and disabling conditions of snoring and obstruction of the human upper airway can result in chronic fatigue, lost work and accidents caused by daytime drowsiness. To date the behaviour of the upper airway has not been adequately studied in terms able to reveal the mechanical causes of these conditions. This deficiency is addressed through the development and use of simulation tools ....Modelling and Measurement of Flow-Structure Dynamics in the Human Upper Airway. Sleep disruption due to the common and disabling conditions of snoring and obstruction of the human upper airway can result in chronic fatigue, lost work and accidents caused by daytime drowsiness. To date the behaviour of the upper airway has not been adequately studied in terms able to reveal the mechanical causes of these conditions. This deficiency is addressed through the development and use of simulation tools and measurement techniques that will elucidate the flow-structure dynamics leading to new diagnostic and improved treatment methods. Simulating the effect of treatment on any individual will permit it to be chosen to maximise its efficacy for a problem that costs the nation an estimated $2 Billion per year in lost productivity.Read moreRead less

The recent development of the world's first prototype combined MR-PET scanner for human use has prompted immense interest. MR-PET is likely to revolutionize clinical diagnosis and basic research, by providing exquisite structural images co-registered with simultaneous functional PET images. We will exploit the as yet unexplored potential for motion information derived from the MR system to be used to correct the simultaneously acquired PET data for patient motion. This research is an excellent opportunity for Australian researchers to make important contributions to an emerging technology with high economic potential, and will strengthen Australia's international position in engineering and biomedical systems development.Read moreRead less
