Reducing waste of consumables in chemical reactions promises to solve environmental problems as well as enable novel applications in space. This project aims to establish a revolutionary fluid handling technology that lowers waste in the labs and in satellites. The project deciphers the fundamental physics behind our recent discovery of encapsulating a tiny liquid content in a solid shell, allowing for handling liquid samples like solid particles. Examples of the benefit of this project are more precise detection of bacteria on earth and compact reactors in space. The research outcomes are instrumental for promoting a clean environment, good health, and creating new business opportunities, particularly in space industry, for Australians.Read moreRead less
Beyond the diffraction limit: sub-diffraction T-ray biochip sensing using planar metamaterials. T-rays are able to detect small changes in molecular structure and different isomeric and intermolecular configurations. With a comparatively long wavelength (0.3 mm at 1 THz), diffraction limits its use for imaging small biosamples. A method for achieving sub-diffraction sensing, required for biochips, is to adopt near-field techniques. However, due to the small biosample masses, there is a critical ....Beyond the diffraction limit: sub-diffraction T-ray biochip sensing using planar metamaterials. T-rays are able to detect small changes in molecular structure and different isomeric and intermolecular configurations. With a comparatively long wavelength (0.3 mm at 1 THz), diffraction limits its use for imaging small biosamples. A method for achieving sub-diffraction sensing, required for biochips, is to adopt near-field techniques. However, due to the small biosample masses, there is a critical need to enhance the response. This project will investigate a planar metamaterial thin-film T-ray sensor, for a new leap in non-invasive biochip sensing. This outcome will build downstream IP for rapid screening of DNA and proteins for healthcare. The project will also elucidate the science of T-ray interaction with biomaterials at small scales.Read moreRead less
Advanced biosensing in the terahertz (THz) sub-wavelength regime. This project will build on Australian excellence in photonics, exploiting the advanced use of T-rays for sensing of biological substances such as proteins and DNA. For the first time, this will enable contactless automated sensing for high-speed medical screening of diseases, a critical step toward the ultimate vision of customised medicine.

Summary
Terahertz sensing of proteins associated with Alzheimer's disease. This project aims to use terahertz radiation to study the proteins associated with Alzheimer's Disease (AD) in order to contribute towards the development of an accurate, non-invasive diagnostic tool. The project will increase our knowledge of the causes of AD, improve its diagnosis, and allow for better treatment to target the symptoms of AD.
Protein biosensors for detecting smoke exposure of grapes. Bush fires and controlled burns that take place in the vicinity of vineyards can lead to grape contamination with tasteless phenolic glucosides. Their hydrolysis during wine making leads to “smoke taint” – an unpleasant medicinal taste that can render wine undrinkable. We will apply a combination of organic synthesis, protein engineering and directed evolution to develop protein-based biosensors of phenolic glucosides. These biosensors w ....Protein biosensors for detecting smoke exposure of grapes. Bush fires and controlled burns that take place in the vicinity of vineyards can lead to grape contamination with tasteless phenolic glucosides. Their hydrolysis during wine making leads to “smoke taint” – an unpleasant medicinal taste that can render wine undrinkable. We will apply a combination of organic synthesis, protein engineering and directed evolution to develop protein-based biosensors of phenolic glucosides. These biosensors will be used to devise a simple portable colorimetric test that can be performed in the vineyard or the winery. The ability to rapidly determine the level of grape contamination with phenolic glucosides would give Australian wine growers and wine makers a powerful tool to mitigate the effects of bushfires.Read moreRead less
Quantitative multi-modal optical imaging of deep tissue. This project aims to create new tools to quantify the structural and functional properties of tissue. Combining multiple optical imaging technologies (multi-modal) into a single, miniaturised probe, these tools could enable physiologists and biomedical researchers to obtain new insight into disease.

This project aims to create new tools to quantify the structural and functional properties of tissue. Combining multiple optical imaging technologies (multi-modal) into a single, miniaturised probe, these tools could enable physiologists and biomedical researchers to obtain new insight into disease. Encasing the highly miniaturised probe within a medical needle is aimed to allow insertion of the 'needle probe' deep into tissue, extending optical imaging to areas not previously accessible. The project could develop novel quantification models to allow longitudinal assessment and comparison between subjects. Validating the tools with specific biomarkers, it could provide outcomes in breast and liver cancer, and a framework to explore other diseases.Read moreRead less
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
Electrochemical biosensors for detection of cardiac disease markers in blood. Cardiovascular diseases leading to heart failure have a prevalence of over 16 per cent in Australia. The social, economic and health burden is higher than for any other disease group. Hence, it is critically important to develop fit-for-purpose sensors of known cardiac biomarkers, which alert patients and clinicians of the risk of imminent heart failure.

Parametric distributions are fundamental to statistical modelling and inference. For centuries, the ‘normal’ distribution has been the dominant model for continuous data.

This project seeks to explore new models for handling data with non-normal features. Parametric distributions are fundamental to statistical modelling and inference. For centuries, the ‘normal’ distribution has been the dominant model for continuous data. However, real data rarely satisfy the assumption of normality. There is thus a strong demand for more flexible distributions. This project aims to develop new methodologies in finite mixture modelling using skew component distributions to provide better models for handling data with non-normal features (such as skewness, heavy/light tails, and multimodality). Applications may include security intrusion detection, clinical diagnosis and prognosis, and flow and mass cytometry.Read moreRead less

ARC Research Hub for Integrated Device for End-user Analysis at Low-levels. This hub aims to improve detection of biological materials by building a portable device for rapid, time-critical detection of low-abundance molecular and cellular analytes. It is expected that the resulting technologies would be used at medical points of care, ordinary workplaces and centres of activity to test for tiny levels of targeted molecules. The initial focus would be early diagnosis of disease and point-of-care drug testing for humans and animals, but the technology platform could be used to sample food and environmental toxins. The hub expects these disruptive technologies will make Australian biotechnology, diagnostics, veterinary, agribusiness and manufacturing firms globally competitive.Read moreRead less
