This project aims to develop highly sensitive chemical sensors for aromatic compounds which will quantify their concentration, in situ, without elaborate sample preparation or instrumentation. The sensors will employ advanced supramolecular chemistry in which the aromatic molecule becomes trapped within a binding cavity in the three dimensional structure of a larger receptor molecule. Coincident with the entrapment a change in the fluorescence level of the receptor occurs which signals the presence of the aromatic compound and its concentration. This research will stimulate economic and social benefits through the development of new environmental and medical sensing techniques and analytical diagnostics.Read moreRead less

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

Porous silicon biosensor for rapid detection of water-borne contaminants. We have recently demonstrated the rapid degradation of porous silicon by certain transition metal complexes known as biomimetic catalysts. The catalysed degradation forms the basis of a new sensor principle where the porous layer serves as matrix, transducer and signal amplification stage. Using this mechanism, we will develop a biosensor for the rapid detection of contaminants (toxins etc.) in water resources.

We have recently demonstrated the rapid degradation of porous silicon by certain transition metal complexes known as biomimetic catalysts. The catalysed degradation forms the basis of a new sensor principle where the porous layer serves as matrix, transducer and signal amplification stage. Using this mechanism, we will develop a biosensor for the rapid detection of contaminants (toxins etc.) in water resources. Reservoir water treatment today is reactive rather than preventive because current analysis is slow. Our biosensor can be turned into a field kit to improve water quality management and prevent acts of deliberate sabotage to the water supply.Read moreRead less

Recent development in machine learning (ML) has seen ML models with extremely high prediction accuracy. However, to support human-machine partnership in decision-making in complex environments, beyond accuracy, it is essential for ML systems to be competency aware and reliable, and at the same time be exploratory.
