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
Disruptive approaches to biological sensing. Optical fibre-based biosensors have the potential to transform our ability to monitor our environment, protect our nation's assets and safeguard our citizens, and to offer improved clinical diagnostics and food quality control by creating tools that can detect biomolecules in real-time within complex samples. To fulfil this mission, we propose to develop new fibre-based sensing architectures for sensing biomolecules that have the potential to be sensi ....Disruptive approaches to biological sensing. Optical fibre-based biosensors have the potential to transform our ability to monitor our environment, protect our nation's assets and safeguard our citizens, and to offer improved clinical diagnostics and food quality control by creating tools that can detect biomolecules in real-time within complex samples. To fulfil this mission, we propose to develop new fibre-based sensing architectures for sensing biomolecules that have the potential to be sensitive, selective, fast and compact.Read moreRead less
Closing the data gap: High throughput screening of nanoparticle toxicity. The nanotechnology sector is experiencing an exponential growth period with over 100 products containing manufactured nanoparticles entering the market every year. Ensuring growth of the sector needs to be balanced against the imperative of protecting both human and environmental safety.

The nanotechnology sector is experiencing an exponential growth period with over 100 products containing manufactured nanoparticles entering the market every year. Ensuring growth of the sector needs to be balanced against the imperative of protecting both human and environmental safety. This project aims to develop new methodological and conceptual avenues to close the gap between innovation in nanotechnology and risk assessment. This is intended to be achieved by developing and validating high-throughput in vitro toxicity screening platforms for manufactured nanoparticles. The approach is based on advanced lab-on-a-chip microfluidic technologies. The predictive power of the platform will be refined and optimised via ex-vivo and in-vivo models.Read moreRead less
Ion channel biosensors based on porous waveguides. Realising the importance of membrane proteins for the functioning of every organism, this project will develop technology to investigate membrane protein functions based on a novel approach combining nanotechnology and biology. The technology will lead to a bio-inspired sensor device capable of detecting minute quantities of molecular analytes.
