Electric field induced surface attachment and detachment of proteins. Microarrays are revolutionising the diagnosis of disease by enabling large amounts of data on genetics and protein expression to be obtained from one sample. Biosensors for diseases and toxins rely on the same mechanism, namely attachment of biological macromolecules to a surface. We propose a new method for controlling the attachment by micromachining an electrode system to apply an electric field to chosen sites.

Microarrays are revolutionising the diagnosis of disease by enabling large amounts of data on genetics and protein expression to be obtained from one sample. Biosensors for diseases and toxins rely on the same mechanism, namely attachment of biological macromolecules to a surface. We propose a new method for controlling the attachment by micromachining an electrode system to apply an electric field to chosen sites. Ultimately microelectronic engineering methods will be used. This will give control over the attachment process with potential benefits of orienting attaching molecules, minimising non-specific attachment and enriching diagnostics by enabling interrogation of the force of attachment.Read moreRead less

Nano infrared and sub micron raman spectroscopy and imaging: Near-field Infrared (IR) spectroscopy and imaging systems will be coupled to near-field scanning optical microscopes to provide IR spectroscopy and molecular images at less than 20 nanometre lateral resolution. This is unprecedented resolution for infrared fingerprinting and molecular imaging. For two months a year the spectroscopy system will be coupled to the IR beamline at the Australian synchrotron, to provide full IR spectral coverage available to all Australian and New Zealand scientists. A confocal raman spectrometer will be upgraded to the ultraviolet to provide spectra at less than 150 nanometre resolution. These systems will provide a unique Australian resource for nanoscientists, biomedical researchers and materials scientists requiring molecular information on the nanoscale.Read moreRead less

Responding to an urgent need to advance rapid molecular diagnostics, this project aims to explore new photonics and biochemistry approaches to DNA recognition. It is anchored on proprietary light-emitting nanodots which have single-molecule sensitivity in conjunction with tunable optical identities. The project aims to develop a multiplexing reagent library of DNA probes to sense trace DNA molecules and to recognise multiple pathogens in a single assay. This innovation aims to create a hybrid-Polymerase Chain Reaction (PCR) technology platform for current industry-standard pathogen detection tests. The outcomes of the project aim to enable DNA based pathogen diagnostics within 90 minutes, four times faster than the current tests.Read moreRead less

This project aims to develop a new drug screening system using nanomaterials interfaced with advanced mass spectrometry to improve testing speed, cost, and accuracy, and minimise the distress associated with current drug testing programs within corrective services. Currently, testing programs are costly, with confirmation taking multiple weeks, preventing appropriate responses to drug use and support service recommendations. Additionally, vulnerable people in custody or on corrective orders find conventional urine testing distressing, especially when previously exposed to sexual violence. New accurate, rapid saliva testing on-site will revolutionise drug monitoring and provide an Australian designed solution for correctional jurisdictions. Read moreRead less
