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

The central aim of this project is to develop a novel technology/sensor platform for rapid, quantitative, multiplexed and highly sensitive point-of-care diagnostics using surface-enhanced Raman spectroscopy (SERS) as the read-out approach. Three-dimensional plasmonic superstructures as novel SERS labels will be synthesised and characterised at single-particle level and the choice of optimal SERS-active three-dimensional superstructures for use will be guided by empirical structure-activity correlations in combination with computer simulations. Tumour biomarkers for breast cancer will be employed as the model target for establishing the detection platform in a portable configuration for point-of-care diagnostics.Read moreRead less

This project aims to develop an antibody based biosensor for the detection of glycosylated haemoglobin (HbA1c) which serves as a marker of the effectiveness of a diabetic’s blood glucose treatment regime. Monitoring HbA1c is important as many of the long term health effects of diabetes are a consequence of high blood glucose levels. The simple to use technology will be a general detection strategy for proteins and hence will be applicable for the detection of a wide range of diseases and biomarkers. The research will also benefit Australia by training the new generation of scientists for Australia's biomedical diagnostics industry.Read moreRead less
