A gold-coated magnetic nanoparticle biosensor for detecting microRNA. The project aims to develop a biosensor for detecting short sequences of RNA, called microRNA (miRNA) in blood. There are about 100 miRNA sequences that are involved in most biological processes. Changes in the levels of some miRNA sequences can serve as a biomarker for many diseases including cancers. The miRNA will be detected using gold-coated magnetic nanoparticles modified with DNA sequences complementary to the miRNA of ....A gold-coated magnetic nanoparticle biosensor for detecting microRNA. The project aims to develop a biosensor for detecting short sequences of RNA, called microRNA (miRNA) in blood. There are about 100 miRNA sequences that are involved in most biological processes. Changes in the levels of some miRNA sequences can serve as a biomarker for many diseases including cancers. The miRNA will be detected using gold-coated magnetic nanoparticles modified with DNA sequences complementary to the miRNA of interest to capture the miRNA. Application of a magnetic field allows the levels of miRNA to be detected electrochemically. The expected outcome is a commercialisable biosensor for miRNA both as a diagnostic early detection device and a prognostic device for a range of miRNA biomarkers.Read moreRead less
Electrochemical biosensors for detection of cardiac disease markers in blood. Cardiovascular diseases leading to heart failure have a prevalence of over 16 per cent in Australia. The social, economic and health burden is higher than for any other disease group. Hence, it is critically important to develop fit-for-purpose sensors of known cardiac biomarkers, which alert patients and clinicians of the risk of imminent heart failure.

Summary
Flexible data modelling via skew mixture models:challenges and applications. This project seeks to explore new models for handling data with non-normal features. Parametric distributions are fundamental to statistical modelling and inference. For centuries, the ‘normal’ distribution has been the dominant model for continuous data. However, real data rarely satisfy the assumption of normality. There is thus a strong demand for more flexible distributions. This project aims to develop new methodol ....Flexible data modelling via skew mixture models:challenges and applications. This project seeks to explore new models for handling data with non-normal features. Parametric distributions are fundamental to statistical modelling and inference. For centuries, the ‘normal’ distribution has been the dominant model for continuous data. However, real data rarely satisfy the assumption of normality. There is thus a strong demand for more flexible distributions. This project aims to develop new methodologies in finite mixture modelling using skew component distributions to provide better models for handling data with non-normal features (such as skewness, heavy/light tails, and multimodality). Applications may include security intrusion detection, clinical diagnosis and prognosis, and flow and mass cytometry.Read moreRead less

Synthesis and characterisation of cadmium-free quantum dots. Quantum dots (QDs) - a highly functional class of nanocrystals - have a tremendous potential for applications in life sciences, energy conversion and electronics; however, their toxicity represents a problem for almost any utilisation. This project aims to find new synthesis methods for less toxic QDs and will thus pave the way for the use of these particles.
Detection of infrared-biomarkers for the diagnosis and treatment of canine neoplasia. This research hopes to discover infrared-biomarkers for canine cancers using synchrotron infrared and laser light. Many dog cancers are similar to human cancers so cancerous tissues and cells from dogs make excellent models for human cancer research. This project will provide new insights and technological approaches to cancer diagnosis and treatment.

Nanodiamond in glass: a new approach to nanosensing. This work will develop optical materials enriched with diamond nanoparticles. This will enable the magnetic field sensitivity of diamond nanoparticles to be combined with the capacity of micro/nanostructured optical fibres to enhance the interaction of light with matter. The outcome will be tools for probing biological processes on the nanoscale.
Development of a diagnostic microarray to detect aneuploidy in single cells. Chromosomal abnormalities account for about 10 per cent of all babies born with a defect. The risk of chromosomal abnormalities increases with maternal age and in patients with fertility problems. It has been estimated that 50 per cent of all embryos are aneuploid. Chromosomal aberrations also occur in the vast majority of tumours in humans. Accurate and rapid detection of chromosomal defects is an important health ser ....Development of a diagnostic microarray to detect aneuploidy in single cells.

It has been estimated that 50 per cent of all embryos are aneuploid. Chromosomal aberrations also occur in the vast majority of tumours in humans. Accurate and rapid detection of chromosomal defects is an important health service delivered to the Australian public. This project aims to develop better tests for application in prenatal diagnostics including non-invasive testing of fetal cells from maternal circulation or cervical samples at 6-13 weeks gestation, IVF and cancer diagnostics.Read moreRead less
