This project aims to investigate fundamental noise in optical coatings, a limiting factor for state-of-the-art astronomical observatories, global timing standards, and photonics applications. Gravitational wave detectors, marvels of precision engineering that have produced ground-breaking discoveries in fundamental science, are particularly afflicted by coating noise. The proposed experiment plans to operate at cryogenic temperatures with unprecedented sensitivity to conduct feasibility studies of deposition methods, coating materials, and layer structures. The goal is to deploy innovative methods to develop Australian-made optical coatings with superior performance and merit for the most demanding scientific and industrial applications.Read moreRead less

The aim of this research is to provide a simple method for creating complex 3D cell cultures for in vitro cell based assays using 3D printing. A versatile polymer system as a bioink made from entirely commercially available components, will be advanced that gives a full range of soft tissue mimics and which can be dynamically change on-demand after printing of the 3D cell cultures. The latter will provide in vitro mimics of in vivo events never previously possible with more realistic models of what is found in vivo. Applications are in fundamental cell biology, studying diseases and developing new drugs. The outcomes from this research will be new knowledge on designing cheap extracellular matrix mimics and high throughout 3D cell assays.Read moreRead less
New biosensing strategies based on bipolar electrochemiluminescence. Chemical analysis is a vital activity in our society, which is to a large extent confined to scientific laboratories and carried out with complex instrumentation.

Chemical analysis is a vital activity in our society, which is to a large extent confined to scientific laboratories and carried out with complex instrumentation. The breakthrough technology envisioned in this proposal will pave the way for simple, low-cost tests which can be used by non-scientists. The development of small, portable sensors for applications ranging from pollution monitoring to health testing, will enable ordinary people to gain knowledge about the concentrations of molecular compounds in their environments and in themselves. This will stimulate economic and social benefits related to environmental testing and early disease diagnosis and generate new commercial opportunities for the Australian biotechnology industry.Read moreRead less

This project aims to develop and implement an alternative approach to the current methods of monitoring of oxygen and toxic gas levels. The aim is to use novel gelled electrolytes based on ionic liquids and polymers, combined with miniaturised sensor devices, to create a robust membrane-free and spill-less design. Amperometric gas sensors are commonly employed to monitor oxygen and toxic gas levels, but the technology used is still based on a 1950s design. The expected outcome of the project is to make fundamental advances in the design of materials that are not affected by humidity changes and which impart selectivity towards particular gases. This will provide the basis for a new generation of low-cost, miniaturised, selective sensors for use in applications such as wearable toxic gas sensors, and as leak detectors on hydrogen-powered vehicles.Read moreRead less
3D printed microchemical devices and systems. This project aims to address the barriers faced by 3D printing in chemistry. 3D printing can create bespoke 3D structures within a fraction of time and cost compared to traditional fabrication. However, its scope in chemistry has been limited by the poor chemical robustness, biotoxicity and low resolution of the 3D printed components.

However, its scope in chemistry has been limited by the poor chemical robustness, biotoxicity and low resolution of the 3D printed components. Hence, this project will develop novel gold coating techniques and explore high-resolution 3D printing to overcome these challenges. The project should generate commercially significant products (analytical platforms), technology (gold coating) and patents. The developed systems and technologies will address Australian research challenges in advanced manufacturing and enable on-site environmental monitoring.Read moreRead less

The project aims to measure mechanics at the cellular level using a combination of optical tweezers for measurement of nano-scale environment around/inside cells and light-sheet microscopy for imaging. The project expects to generate new knowledge about movement of cells through their environment, relating to collective behaviour which is of importance in understanding infections and formation of biofilms. Expected outcomes include deepened understanding of an enigmatic process conserved from amoebae to humans, by which cells ‘drink and eat’ by ‘gulping’ fluid and supplement their nutrient intake by degrading proteins and cell debris. It will generate new knowledge of these processes to better understand how mechanics affects cellular life.Read moreRead less
