This project will investigate the use plasmonic absorption of light in metal nanostructures to activate the selective oxidation/reduction of a gas molecule on a semiconductor nanoparticle. This concept will be used with the aim of developing a sensing technique capable of measuring ultra-low concentrations (ppb) of breath markers for lung cancer detection. It is expected that porous sensing films of semiconductor and metal nanoparticles with well-defined light absorption properties will be fabricated. Superior selectivity will be achieved by matching the wavelength of the absorbed light with the required activation energy for oxidation/reduction. Successful outcomes will enable multi-analyte fingerprint identification by on-chip devices with applications ranging from portable medical diagnostics to national security.Read moreRead less
Transformational diagnostics. Australia has established world-leading capabilities in optical fibres and surface science that, when brought together, have the potential to transform applications that require non-invasive, real-time and/or portable biological detection tools. We propose a novel and ambitious suite of projects that bring together these capabilities with experts in reproductive health, forensics and explosives to solve pressing problems in each of these areas that have the promise ....Transformational diagnostics.

Vapour phase detection of chemical warfare agents. This project aims to create luminescent plastic optoelectronic materials that can detect airborne chemical warfare agents, particularly nerve agents. Such agents are often odourless and invisible at lethal concentrations, so technology must detect and identify them before exposure. The intended outcomes are design rules for sensitive and selective materials that can be used in a handheld infield detector to sense chemical warfare agents based on ....Vapour phase detection of chemical warfare agents.

Such agents are often odourless and invisible at lethal concentrations, so technology must detect and identify them before exposure. The intended outcomes are design rules for sensitive and selective materials that can be used in a handheld infield detector to sense chemical warfare agents based on the materials’ photophysical properties, and new analytical methods and sensing protocols. This research will be of interest to security agencies in Australia and internationally, and will better protect our military.Read moreRead less

Hybrid nanowire-nanoantenna infrared photodetectors. This project aims to demonstrate room temperature hybrid nanowire-nanoantenna infrared photodetectors by integrating plasmonic nanoantennas on semiconductor nanowire arrays.

It is expected that such novel device architectures will not only bring enhanced performance in responsivity, detectivity, and photoresponse bandwidth, but also additional functionalities such as selective wavelength and tunable polarisation, which may significantly outperform current infrared technology.

Brighter than a synchrotron mid-infrared sources for spectroscopy & sensing. This project intends to develop mid-infrared spectroscopy as a powerful diagnostic tool. Mid-infrared spectroscopy allows a light beam to determine the chemical composition of objects or gaseous samples.

This project intends to develop mid-infrared spectroscopy as a powerful diagnostic tool. Mid-infrared spectroscopy allows a light beam to determine the chemical composition of objects or gaseous samples. It has wide applicability — in fields such as medicine, agriculture, the environment, national security and industrial process control — but its use has been hampered by the lack of bright, low-cost sources and integrated devices. This project aims to implement new Australian-made sources that exceed the brightness of even synchrotrons at modest prices. It also aims to demonstrate a single chip integrated version of such a source as the first step towards deployment of mid-infrared technology.Read moreRead less
Solid-state quantum communication technology. This project will develop the quantum information devices required to create a quantum communication network for the ultra-secure transmission of data. The key technological challenge is to entangle the quantum state of two crystals separated by kilometres, and maintain this entanglement for many seconds.
