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

Nucleotides for bioelectronics. Bioelectronics is a key component of nanobiotechnology, a new field that merges the science of biological molecules (DNA, proteins etc.) with electronics and semiconductor physics. We have recently introduced redox-labelled nucleotides that enable the production of electrochemically-active DNA and RNA for genetic, forensic and nanotechnology applications. This project further develops redox nucleotides for use in electronic devices.
Study of molecular interactions between wood pitch fixatives and components of wood pitch. Wood resins, released in pulping, agglomerate in the papermaking process to cause pitch deposits. These deposits adversely affect paper machine efficiency and product quality and limit further recycling of process water. This project aims to investigate the interactions between the components of the wood resins and different fixatives using capillary electrophoresis and other techniques.

Wood resins, released in pulping, agglomerate in the papermaking process to cause pitch deposits. These deposits adversely affect paper machine efficiency and product quality and limit further recycling of process water. This project aims to investigate the interactions between the components of the wood resins and different fixatives using capillary electrophoresis and other techniques. This knowledge will provide a better understanding of the role of the physical and chemical properties of the fixatives in fixing the different compounds in wood resins. Molecular modelling will be used to design new fixatives that will be selective to a mixture of wood resins.

Sulphate sensor for reverse osmosis integrity and performance monitoring. This project aims to investigate new chemical sensors for sulphate for online reverse osmosis integrity and performance monitoring at an advanced water recycling plant. Wastewater re-use is increasingly important in Australia and worldwide for providing potable water. Demonstrating the integrity and performance of treatment technologies is needed to meet health regulations. Sulphate and other surrogates of biological entities enable a rapid, on-line approach to integrity and performance monitoring, but detection with available analytical chemical technology is not feasible. This research is expected to enable better management of water treatment processes and demonstrate compliance to health standards.Read moreRead less

In recent years, the demands put on batteries has increased due to the development of sophisticated portable electronic devices. With the currently available primary battery systems finding it difficult to cope with these demands, there is considerable incentive to develop an improved system with an appropriate capability. This project focuses on nickel(III) oxyhydroxide (NiOOH) as a cathode material. NiOOH is used widely in rechargeable battery systems, where it performs adequately even under severe discharge conditions. However, in primary battery systems, NiOOH suffers from self discharge. This project aims to use the performance capabilities of NiOOH in a primary system, by investigating ways to improve its stability. The benefits for Delta EMD will be protection of their existing business, as well as opening the door to the commercial manufacture of an advanced export material.Read moreRead less

Dyno Nobel Asia Pacific is a major supplier of explosive services to the coal, iron ore and gold-mining industries. Many mines in Australia and overseas are in hot and reactive ground, where eliminating the risk of spontaneous detonation is a considerable addition to operating costs. The Company and the University will collaborate to significantly improve our capacity to evaluate ground for reactivity and to formulate new inhibited emulsion explosives for use in hot and reactive ground. This will lead to much more flexible, cost-effective mining operations, by understanding the key parameters for the safe ‘sleep time’ of on-site explosives. This should result in greater export competitiveness and rural employment opportunities. Read moreRead less
