Ultrasensitive electrochemical biosensors. This project aims to develop novel proteins that can convert biochemical cues into electronic signals. Using protein engineering, this project will produce redox protein-based OFF switches. The project expects that the use of the OFF-switches (as opposed to ON switches) will simplify biosensor design and create a new class of sensory architectures. Integration of OFF-switch-based biosensors with an enzymatic signal amplification circuit is expected to y ....Ultrasensitive electrochemical biosensors. This project aims to develop novel proteins that can convert biochemical cues into electronic signals. Using protein engineering, this project will produce redox protein-based OFF switches. The project expects that the use of the OFF-switches (as opposed to ON switches) will simplify biosensor design and create a new class of sensory architectures. Integration of OFF-switch-based biosensors with an enzymatic signal amplification circuit is expected to yield ultrasensitive sensory systems with near-real-time response. The project will address a need for new technologies that enable collection of physiological and environmental information rapidly, and at low cost outside of the specialised laboratories.Read moreRead less
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
High-throughput microfluidic approach to mapping hierarchies of interactions in the gene regulation machinery. The exploration of protein-protein interactions networks is becoming an extremely active area of research in life sciences. The current project will develop new approaches to accelerate the discovery of novel interacting proteins participating in gene regulation, in order to understand how cells differentiate into different tissues and organs.
Proteomic study of urine to discover novel biomarkers for human prostate cancer. The purpose of this project is to identify novel markers in the urine of patients with prostate cancer. These biomarkers may ultimately prove useful in the development of novel diagnostic tools for the management of this disease.
Proteomic study of tears to discover novel biomarkers for human breast cancer. The purpose of this project is to identify novel markers in the tears of patients with breast cancer. The results from this study may improve the prognosis of breast cancer patients.
Imaging Mass Spectrometry (IMS), a peptide biomarker discovery tool using tissue. Cancer is the second most common cause of death in Australia. The newly developed technology of Imaging Mass Spectrometry for peptides in tissue has the potential to discover biomarkers for early diagnosis of cancer. This new technology could avoid a number of cancer deaths and reduce suffering of patients through earlier and better diagnosis.
Single-molecule optofluidics: streamlining high-throughput engineering and analysis of proteins and protein assemblies. This project aims at creating novel technologies for high-throughput engineering and analysis of proteins with single-molecule sensitivity. The platform will considerably accelerate the generation of protein-based diagnostics, new vaccines and therapeutics; it will foster collaborations with industry putting Australia at the forefront of protein research.
