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.

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
Building bio-inspired smart nanochannels for virus detection. This project aims to harness high-precision silicon nanofabrication methods to create the next generation of bio-inspired viral biosensors. The new technology would enable prompt, cost-efficient, and accurate detection of virus contamination of our water and food supplies. The project plans to fabricate arrays of parallel double-layered nanochannels in silicon via templated etching, with surface functionalisation to display receptors. ....Building bio-inspired smart nanochannels for virus detection.

The new technology would enable prompt, cost-efficient, and accurate detection of virus contamination of our water and food supplies. The project plans to fabricate arrays of parallel double-layered nanochannels in silicon via templated etching, with surface functionalisation to display receptors. These nanochannels are designed to act as size-selective filters for electrochemical and electrochemiluminescence sensing. The project plans to explore innovative signal amplification and multiplexing capabilities for ultrasensitive detection of norovirus and bacteriophages.Read moreRead less
