Summary
Malaria is a major global health problem. 500 million people become infected with malaria parasites every year and 2-3 million people die each year from the disease. Rapid diagnosis of the disease is needed to allow correct treatment protocols. Increasingly protein-based immunochromatographic tests are being employed for the diagnosis of malaria as they offer significant advantages over classical thick smear tests, which require trained personnel and laboratory facilities. We propose to develop ....Malaria is a major global health problem. 500 million people become infected with malaria parasites every year and 2-3 million people die each year from the disease. Rapid diagnosis of the disease is needed to allow correct treatment protocols. Increasingly protein-based immunochromatographic tests are being employed for the diagnosis of malaria as they offer significant advantages over classical thick smear tests, which require trained personnel and laboratory facilities. We propose to develop a protein-based malaria diagnostic that has the ability to distinguish the two major human pathogens, P.falciparum and P. vivax.Read moreRead less
Development Of A Novel Biosensor Using Magnetically Amplified Luminescence For The Early Detection Of Cancer

Summary
Cancer is often not detected until it has invaded surrounding tissues and spread to other organs. Current treatment is then often ineffective, and prognosis poor. Early detection of cancer is therefore essential for improved disease management. Such methods must be cheap, non-invasive, and rapid with high sensitivity and specificity. We are investigating a new biosensor technology that satisfies these criteria. This method uses magnetically amplified luminescence for the detection of low levels ....Cancer is often not detected until it has invaded surrounding tissues and spread to other organs. Current treatment is then often ineffective, and prognosis poor. Early detection of cancer is therefore essential for improved disease management. Such methods must be cheap, non-invasive, and rapid with high sensitivity and specificity. We are investigating a new biosensor technology that satisfies these criteria. This method uses magnetically amplified luminescence for the detection of low levels of cancer cells in clinical samples (urine, faeces, blood, biopsy), using telomerase as a marker.Read moreRead less
The multiplexed diagnosis of arbovirus infections using combinatorial probes. Viruses that cause serious diseases such as hemorrhagic fever or encephalitis must be quickly identified. Diagnostic tests based on DNA hybridisation are accurate and can be rapid but they are expensive. We will test a method for simplifying DNA tests and increasing their capabilities. DNA probes for detecting arboviruses will be designed at the ANU using new bioinformatic methods and their reliability will be model ....The multiplexed diagnosis of arbovirus infections using combinatorial probes. Viruses that cause serious diseases such as hemorrhagic fever or encephalitis must be quickly identified. Diagnostic tests based on DNA hybridisation are accurate and can be rapid but they are expensive. We will test a method for simplifying DNA tests and increasing their capabilities. DNA probes for detecting arboviruses will be designed at the ANU using new bioinformatic methods and their reliability will be modelled using all the available genetic information. Computer predictions will be experimentally tested in the PANBIO laboratory by using the probes to detect viral nucleic acids. The influence of virus genome complexity will be investigatedRead moreRead less
Detection of imported exotic strains of West Nile virus for national biosecurity surveillance. West Nile virus (WNV) is transmitted by mosquitoes and causes a fatal disease of the brain in animals and humans. WNV is currently exotic to this country, however a closely related, but benign cousin of this virus (Kunjin) can be found in Northern Australia. Currently it is very difficult to differentiate between infections with WNV and Kunjin using standard laboratory tests, therefore it will be diff ....Detection of imported exotic strains of West Nile virus for national biosecurity surveillance. West Nile virus (WNV) is transmitted by mosquitoes and causes a fatal disease of the brain in animals and humans. WNV is currently exotic to this country, however a closely related, but benign cousin of this virus (Kunjin) can be found in Northern Australia. Currently it is very difficult to differentiate between infections with WNV and Kunjin using standard laboratory tests, therefore it will be difficult for public health officials to detect WNV if it is introduced to Australia. In this project we aim to develop more accurate laboratory tests to detect infections with the deadly, exotic WNV using new strategies. Read moreRead less
Gene Expression Profiling and de novo Transcriptome Sequencing using Geneballs. 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 ....Gene Expression Profiling and de novo Transcriptome Sequencing using Geneballs. 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 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 project will also generate an ultra-sensitive, rapid technology that can be used for personalized point-of-care diagnostics. The applications can include the detection of disease markers, pathogens or the determination of protein content in a clinical sample. These technologies will be applicable across a spectrum or of diseases all of which will benefit the broader community.Read moreRead less
