The purpose of the project is to demonstrate that bead-based technology can be used in applications that currently require DNA hybridisation in order to overcome existing deficiencies in microarray technology. By providing the capability to quickly and efficiently produce, screen and utilize biomolecule libraries of nearly unlimited size, this technology provides the key to unlock the power of genomics and proteomics for use in real world applications. The project has two aspects. First, relatively small directed cDNA-bead libraries will be compared to known low-density cDNA microarrays to validate the technique for utility in gene expression profiling. Secondly, large libraries containing short oligonucleotide sequences will be used for de novo sequencing of a complete transcriptome. Proof-of-concept in either case will pave the way for many genomic applications and catapult the technology to 'blockbuster' status.Read moreRead less

Development of an ultrasensitive assay for human prion proteins. The aim of this work is to enable the detection of prion proteins in human blood and other tissues. The assay system to be developed will detect much lower levels of these disease-causing proteins than is possible at present; it will be more rapid and will measure prion protein levels more accurately than existing assays. The outcome of the work is expected to facilitate the production and certification of prion-free blood and bl ....Development of an ultrasensitive assay for human prion proteins. The aim of this work is to enable the detection of prion proteins in human blood and other tissues. The assay system to be developed will detect much lower levels of these disease-causing proteins than is possible at present; it will be more rapid and will measure prion protein levels more accurately than existing assays. The outcome of the work is expected to facilitate the production and certification of prion-free blood and blood products. Prions cause Bovine Spongiform Encaphalopathy and Creutzfeld Jacob Disease and attempts to control of these diseases would be greatly abetted by an optimal test for the disease-causing agent.Read moreRead less
The photonic immunochip: retrieving individual Enzyme-linked Immuno Sorbent Assay (ELISA) array-units using optical waveguide multicolour fluorescence. Improving the sensitivity and availability of in-vitro immuno-diagnostic tests is a critical goal towards developing real time efficient tools for the detection of infectious diseases, cancers, allergies and auto-immune diseases.

Improving the sensitivity and availability of in-vitro immuno-diagnostic tests is a critical goal towards developing real time efficient tools for the detection of infectious diseases, cancers, allergies and auto-immune diseases. The goal is to increase the sensitivity of these tests by reducing background noise that has been a feature of the commonly used ELISA technology. This will be achieved by developing a novel optical integrated waveguide array supporting a large range of distributed tests, including several based on a novel multi-colour detection scheme. This massively parallel approach will underpin a new generation of low-cost, efficient diagnostic tests.Read moreRead less
Improved methods for quantitation of acute phase proteins in biological samples. Using monoclonal antibodies and fluorescence polarisation, we aim to develop improved quantitative analytical methods that are superior to the current clinical assays. The initial targets will be C-reactive protein (CRP) and serum amyloid precursor protein (SAP), but the technology should be readily adaptable to other serum proteins. Better assays for CRP and SAP will greatly facilitate improved clinical management ....Improved methods for quantitation of acute phase proteins in biological samples. Using monoclonal antibodies and fluorescence polarisation, we aim to develop improved quantitative analytical methods that are superior to the current clinical assays. The initial targets will be C-reactive protein (CRP) and serum amyloid precursor protein (SAP), but the technology should be readily adaptable to other serum proteins. Better assays for CRP and SAP will greatly facilitate improved clinical management of those at risk of heart attack, the single biggest contributor to healthcare costs in Australia. We further aim to adapt this technology to enable "point-of-care" assays that would help medical practitioners, especially in rural areas, to make informed diagnoses immediately.Read moreRead less

The epidemiology of canine gastrointestinal parasitic zoonoses in different community settings in Thailand. The dog's role in transmitting zoonotic gastrointestinal parasites to humans has been recognised as a significant public health problem worldwide. Surveillance data with regard to canine parasites in Thailand and its regional countries is largely lacking, especially with regard to the dog's role as a perpetuator of the liver and intestinal flukes.

The dog's role in transmitting zoonotic gastrointestinal parasites to humans has been recognised as a significant public health problem worldwide. Surveillance data with regard to canine parasites in Thailand and its regional countries is largely lacking, especially with regard to the dog's role as a perpetuator of the liver and intestinal flukes. This project aims to provide an accurate and comprehensive assessment of the risks these parasites pose to the public using a combination of conventional and novel molecular epidemiological tools. Successful completion of this project will provide a model for control programs to be generated in the SE Asian region.Read moreRead less
