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

Bioinspired liposome-based smart sensors. This project aims to develop a liposome-based biosensor technology that mimics cell sensory systems. Selective detection of compounds is increasingly important for food, health and environmental monitoring. Biosensor development faces long-standing challenges such as response time, sensitivity, specificity, and multiplexing. On the other hand, cells can sense and discriminate multiple biomolecules in seconds with high sensitivity and specificity. This pr ....Bioinspired liposome-based smart sensors.

This project aims to harness cells’ exquisite biological properties to improve current detection techniques. It will integrate liposome-based sensors with microfluidics to perform analytical tasks ranging from food safety to diagnostics.Read moreRead less
New strategies for characterising and monitoring protein-surface interactions: application to a biosensor for diabetic’s blood glucose regime effectiveness. 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.

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

Summary
Polymer micropatches applied to the skin for integrated capture and detection of circulating biomarkers. The purpose of this project is to develop a rapid and integrated technology for user-friendly biomarker detection at the point-of-care. We expect the device to rapidly detect proteins and/or antibodies, without the need for highly trained health workers or access to scientific laboratories.

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

The first generation of single entity measurement tools for analysis: This fellowship project aims to develop a new type of diagnostic device that measures single molecules or single cells. Such measurements seek to revolutionise analysis by allowing heterogeneity and rare events in samples to be identified, rather than the average information provided by existing tools. With single molecule devices, the heterogeneity in response enables the development of multiplexed, calibration free sensors. The outcomes of the project are hoped to be completely new thinking on performing measurements, new knowledge regarding heterogeneity in biology and the potential for novel commercialised sensors. It is expected that this will be important not only in biological discovery, but also in providing far more robust sensors for applications such as environmental monitoring, disease prediction, personalised medicine or drug discovery.Read moreRead less
