This project aims to develop a technological platform for the fabrication of miniaturised and flexible sensors that enable the quantitative detection of important bioactive compounds such as fatty acids and biogenic amines. By utilising multi-enzymatic reactions in solid phase and engineering task-specific inks, chemiresistive sensors will be printed seamlessly as a whole. The sensors will respond to complex target biomolecules via a series of enzymatic reactions through which the analyte will convert to much simpler, reactive and hence measurable molecules. This project will enable to design miniaturised sensors for point-of-care detection of biomolecules that cannot be yet evaluated by the end users.Read moreRead less
Epigenetic and biomarker approaches to improving dairy cow fertility. The dairy industry will not deliver sustainable higher productivity unless the reproductive performance of dairy cows is significantly improved. This expected outcome will be achieved via the identification of epigenetic and protein biomarkers of improved fertility that will be used to develop superior breeding stock. Caruncular and intercaruncular tissues and blood have been obtained from both fertile (New Zealand Holstein-Fr ....Epigenetic and biomarker approaches to improving dairy cow fertility. The dairy industry will not deliver sustainable higher productivity unless the reproductive performance of dairy cows is significantly improved. This expected outcome will be achieved via the identification of epigenetic and protein biomarkers of improved fertility that will be used to develop superior breeding stock. Caruncular and intercaruncular tissues and blood have been obtained from both fertile (New Zealand Holstein-Friesian) and sub-fertile (North American Holstein-Friesian) cows within pasture-based dairying systems that include seasonal calving and subclinical uterine inflammation (associated with poor reproductive performance). Determinations will be conducted using deep parallel (next generation) sequencing and mass spectrometry.Read moreRead less
Identification of at-risk transition cows: Use of exosomal biomarkers. This project aims to improve the early diagnosis of cows at risk of infectious disease and debilitating metabolic syndromes. Animal health and longevity are pillars of the dairy industry. The risk of death is up to 6 times greater during the transition from pregnancy to lactation, making this ‘transition period’ the time for detection and intervention. If successful, this project will permit the focus of resources on high ris ....Identification of at-risk transition cows: Use of exosomal biomarkers. This project aims to improve the early diagnosis of cows at risk of infectious disease and debilitating metabolic syndromes. Animal health and longevity are pillars of the dairy industry. The risk of death is up to 6 times greater during the transition from pregnancy to lactation, making this ‘transition period’ the time for detection and intervention. If successful, this project will permit the focus of resources on high risk cows and reduce poor outcomes: lower milk production, involuntary culling and increased cow maintenance costs. Within this overall objective, a cost-effective project design will leverage partner facilities and existing networks to translate findings to farm use, thereby clearly delivering economic value.Read moreRead less

The aim of this project is to develop the first biosensors that prevent nonspecific protein adsorption and allow reversible protein binding. The project expects to achieve this using a combination of novel surface chemistry and pulsed electric fields that dynamically change a sensing interface. The impact of electric fields on the binding of proteins to this interface will be followed using a novel single molecule fluorescence microscope previously developed that can locate the position of proteins with 2 nanometer resolution. The expected outcomes of this project is a class of biosensor that can continuously monitor protein biomarkers for wearable sensors that provide information on a user’s wellness and nutrition.Read moreRead less
Surveillance of the mechanisms controlling proteome foldedness. This project aims to measure how cells keep the proteome folded. Cells have extensive quality control networks to govern synthesis, folding and transport of every protein but the buffering capacity of this system is not definable. This capacity is needed to understand how problems arise in managing proteome foldedness, a central feature of human diseases and biotechnology and synthetic biology applications that need cell-based produ ....Surveillance of the mechanisms controlling proteome foldedness. This project aims to measure how cells keep the proteome folded. Cells have extensive quality control networks to govern synthesis, folding and transport of every protein but the buffering capacity of this system is not definable. This capacity is needed to understand how problems arise in managing proteome foldedness, a central feature of human diseases and biotechnology and synthetic biology applications that need cell-based production of engineered proteins such as hormones and antibodies. The outcomes are expected to provide basic knowledge of this fundamental process and provide biosensors and screening methods for use in health and biotechnology industries.Read moreRead less

Based on a novel sensing principle, they will offer performance comparable with current laboratory-based techniques. They will be rapid (< 1 h), cost -effective (< $ 1 per strip) and robust. Project outcomes will include tube-based tests able to detect 1 DNA copy / microlitre and ultralight paper test strips, both with naked-eye readout. Applications of these sensors in water testing will be developed with an Australian industry partner Biopoint. Benefits will include strengthened protection against invasive pests and the spread of antimicrobial resistance without lab testing and sample logistics.Read moreRead less
Image-guided skin microbiopsy technology development. There is a need for targeted biopsies in dermatology. This novel technology enables minimally invasive biopsies to be taken from suspicious skin lesions by integrating micromedical and imaging devices.
Novel technologies for motion-compensated simultaneous Magnetic Resonance Imaging (MRI) and Positron Emission Tomography (PET) imaging. The aim of this work is to develop motion tracking and motion correction techniques for an emerging hybrid imaging technology, MR-PET. The MR-PET scanner simultaneously acquires structural MR images and functional PET images. The work will provide clearer images without the effects of motion blur for both research and clinical applications.
The colour of cellular aging: a deep probe of cellular processes.

Understanding why we age and whether aging is preventable are profound research challenges, which must be first tackled at a cellular level. Building on our advances in non-invasive colour monitoring of cell function, this project aims to uncover intimate links between cellular processes and aging in cells that must survive for many decades such as oocytes and neurons. We will explore the tantalising possibility to rejuvenate such aged cells by interfering with molecular master switches of aging. A unique machine learning approach will be applied for finding the most effective interventions. The results will have broad impact beyond the science of aging, in the areas of female fertility, neurodegeneration and immunity.
