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

Summary
Quantum Dots, a type of nanocrystal, have been shown to emit light at a very precise wavelength. Quantum dots of approximately 5 nm in diameter have been conjugated to a silica microsphere and then coated with free silica, thus encasing the Quantum Dots in a small chamber surrounding the microsphere. This structure is analogous to a light globe under a lampshade. Just as one can change the nature of the lamplight by changing the lampshade, one can change the Quantum Dot emitted light by changing ....Quantum Dots, a type of nanocrystal, have been shown to emit light at a very precise wavelength. Quantum dots of approximately 5 nm in diameter have been conjugated to a silica microsphere and then coated with free silica, thus encasing the Quantum Dots in a small chamber surrounding the microsphere. This structure is analogous to a light globe under a lampshade. Just as one can change the nature of the lamplight by changing the lampshade, one can change the Quantum Dot emitted light by changing the surface of the microsphere. Since the scale is so small (each microsphere is about the size of a single bacterial cell), the amount and nature of the material needed to bind to the surface to effect a detectable change is also very small, on the order of just of few tens or hundreds of molecules. This project seeks to exploit this principle to create a new class of ultra sensitive detector which can be used in many sorts of applications such as medical diagnostics and biosensing.Read moreRead less
Development Of A Serum Based Test For Aggressive Prostate Cancer.

Summary
Prostate cancer is relatively slow growing, taking decades to reach clinical significance. A critical phase in the progression of prostate cancer is the transformation from latent (or dormant) to aggressive tumours; hence the saying that many men die with prostate cancer, rather than of prostate cancer. We aim to develop a test utilising inhibin-activin proteins as surrogate markers of aggressive disease based on our previous studies of a significant correlation between the expression of inhibin ....Prostate cancer is relatively slow growing, taking decades to reach clinical significance. A critical phase in the progression of prostate cancer is the transformation from latent (or dormant) to aggressive tumours; hence the saying that many men die with prostate cancer, rather than of prostate cancer. We aim to develop a test utilising inhibin-activin proteins as surrogate markers of aggressive disease based on our previous studies of a significant correlation between the expression of inhibins in tissues from men with high grade prostate cancer. This study aims to validate the correlation using serum rather than a tissue based assay.Read moreRead less
Development Of A Sensitive Point Of Care Diagnostic Assay For Troponin I

Summary
This research aims to develop a diagnostic for immediate monitoring of patients presenting with chest pain, with the presumption of heart attack. The novel diagnostic platform will enable the estimation of a key indicator of heart muscle damage to be performed within a ten to fifteen minute window. This will aid speedier diagnosis and propoer triage of patients presenting with chest pain.
Development Of A Prototype Production System For Optical Fibre Diagnostic Probes

Funding Amount
$191,598.00
Summary
Advances in nanotechnology have led to new techniques for the precise fabrication of nanometre scale structures. A recent breakthrough by the applicants now allows high-quality nanostructures to be stamped onto the tip of low-cost optical fibre probes. When coated with silver, these sensitive probes can be used for continuous monitoring of blood glucose in diabetics and in critical care situations. This project aims to develop a prototype manufacturing system for optical fibre glucose probes.
A Novel One-step Approach In The Early Diagnosis Of Prostate Cancer

Summary
In order to avoid the invasiveness and imprecision of current prostate cancer detection, this programme is directed to developing a non-invasive and repeatable, accurate approach. This research project is designed to optimise retrieval of prostate cells from ejaculate and to compare two methods for profiling selected genetic changes to diagnose prostate cancer. The refinement of techniques, outlined in the application, is essential before proceeding to a clinical trial.
Novel Nanoparticle Composites For Molecular Probes In Diagnostic Imaging

Summary
Isotope labelled protein probes, eg. antibodies, are a valuable imaging tool in investigating patient disease. Their biological specificity is their great strength, however, detection sensitivity often limits their use. A novel nanoparticle developed at ANU can increase this signal by a million-fold in comparison with conventional methods of labelling. This approach suits a range of probes and will accommodate many of the isotopes already used in patient diagnostics and therapy.
