This project aims to pioneer technologies to observe and control the microscopic world with unprecedented precision, and apply them to realise practical sensors with unrivalled performance. Nano- and micro-scale sensors will be developed that resolve motion smaller than an atomic nucleus, in a classical spin-off from international efforts to study quantum physics at the nanoscale. Record precision will be achieved in thermometry and magnetometry. New tools will be developed for lab-on-a-chip medical diagnosis and thermal imaging, that in future could allow femtolitre diagnosis of blood diseases such as malaria, on-chip genomic analysis, more efficient airport screening, and more precise satellite maps of global and atmospheric temperature.Read moreRead less

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
Peripheral aberrations of the human eye. This project will benefit Australia from several perspectives. It will make an important contribution to understanding limitations to peripheral vision of the eye, particularly as a result of refractive surgical intervention. This is important because many Australians will require such surgery.

This project will benefit Australia from several perspectives. It will make an important contribution to understanding limitations to peripheral vision of the eye, particularly as a result of refractive surgical intervention. This is important because many Australians will require such surgery. Being able to better measure and correct peripheral aberrations will lead to improved imaging of the eye and thus contribute to improved detection and diagnosis of ophthalmic disease. The study will benefit ophthalmologists, optometrists, and engineers involved in designing visual instruments. This project will provide training in adaptive optics for graduate students not available in any other Australian institution.Read moreRead less

Tuneable “Nano-Shearing”: An Innovative Mechanism for the Accurate and Specific Capture of Cells and Molecules. Recent investigations have discovered a tuneable electro-hydrodynamic force which drives lateral fluid motion within a few nanometers of an electrode surface. Because the magnitude of this fluid shear force can be tuned externally (for example, via the application of an AC electric field), it provides a new capability to physically displace weakly (non-specifically) bound cellular and ....Tuneable “Nano-Shearing”: An Innovative Mechanism for the Accurate and Specific Capture of Cells and Molecules. Recent investigations have discovered a tuneable electro-hydrodynamic force which drives lateral fluid motion within a few nanometers of an electrode surface. Because the magnitude of this fluid shear force can be tuned externally (for example, via the application of an AC electric field), it provides a new capability to physically displace weakly (non-specifically) bound cellular and molecular analytes. By performing research to further understand and develop this tuneable effect, this project aims to build and test a new platform technology to enable highly efficient capture and specific detection of low concentration pathogenic molecules and circulating tumour cells (CTCs).Read moreRead less
Illuminating hidden processes in emissive lanthanoid complexes. This project aims to understand the antenna effect used to sensitise lanthanoid luminescence. Despite their use in modern high-tech applications, from optical fibre amplifiers (telecommunications) to luminescent probes and sensors (biological imaging), understanding is largely based on speculation or generalised 'rules-of-thumb', severely limiting progress in the field.

This project aims to understand the antenna effect used to sensitise lanthanoid luminescence. Despite their use in modern high-tech applications, from optical fibre amplifiers (telecommunications) to luminescent probes and sensors (biological imaging), understanding is largely based on speculation or generalised 'rules-of-thumb', severely limiting progress in the field. This project will research these processes, using chemical synthesis, theory and spectroscopic techniques. This is expected to lead to new emissive lanthanoid-based compounds using 'a priori' approaches, with better performance than current gold standards and references. Intellectual property created will lead to new commercial products, and to creation of new Australian based spin-off/start-up companies.Read moreRead less
