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

ARC Research Hub for Integrated Device for End-user Analysis at Low-levels. This hub aims to improve detection of biological materials by building a portable device for rapid, time-critical detection of low-abundance molecular and cellular analytes. It is expected that the resulting technologies would be used at medical points of care, ordinary workplaces and centres of activity to test for tiny levels of targeted molecules. The initial focus would be early diagnosis of disease and point-of-care drug testing for humans and animals, but the technology platform could be used to sample food and environmental toxins. The hub expects these disruptive technologies will make Australian biotechnology, diagnostics, veterinary, agribusiness and manufacturing firms globally competitive.Read moreRead less

The aim of this project is to develop novel methods for forming robust single-molecule circuitry. The use of single molecules in electronics represents the next level of miniaturisation of electronic components, which would enable us to meet the expanding demands of modern technologies and to continue the downscaling trend in electronic devices. This project aims to address the requirements needed to translate single-molecule electronics from its current status as a fundamental tool to real-world applications. Key approaches will be the use of surface chemistry to develop new methods of wiring single molecules and the integration of robust single-molecule junctions with semiconducting electrodes. The expected project outcomes pave the way for single-molecule electronic and analytical devices.Read moreRead less
