The central aim of this project is to develop a novel technology/sensor platform for rapid, quantitative, multiplexed and highly sensitive point-of-care diagnostics using surface-enhanced Raman spectroscopy (SERS) as the read-out approach. Three-dimensional plasmonic superstructures as novel SERS labels will be synthesised and characterised at single-particle level and the choice of optimal SERS-active three-dimensional superstructures for use will be guided by empirical structure-activity correlations in combination with computer simulations. Tumour biomarkers for breast cancer will be employed as the model target for establishing the detection platform in a portable configuration for point-of-care diagnostics.Read moreRead less

At present there is a need for fast and detailed chemical analysis of complex samples, such as those important to biomedical diagnostics and forensic science. Innovative technology will be developed here in order to reduce analysis time whilst maintaining the integrity of the chemical information contained within the sample. This step change in separation science will directly aid biomedical diagnostics, forensic sample determination and industrial process monitoring through decreased analysis time with an increase in the chemical information gained. By performing chemical separations on a microfluidic scale a reduction in both the cost of analysis and impact of solvent waste on the environment will be achieved.Read moreRead less

This project aims to develop a high-performance, cost-effective, palm-portable differential ion mobility spectrometer for universal chemical analysis that operates at atmospheric pressure and consumes minimal power. A significant problem in current analytical chemistry is the lack of rapid and cost-effective methods that can be used in the field for analysis of many different chemical species of environmental and biological importance. The project expects to enable the rapid and simultaneous separation and detection of many different ions from complex mixtures with high selectivity and sensitivity. The spectrometer can be implemented in the field for various applications such as atmospheric monitoring, disease diagnosis and chemical weapons detection.Read moreRead less

This project aims to develop Artificial Photonic Cells by directly coating photonic crystals with cell membranes. The Artificial Photonic Cells retain the protein receptors in their native cell membrane environment and allow for label-free monitoring of the receptor-ligand interactions using inexpensive miniature spectrometers - radically transforming these assays. This would generate fundamental and applied knowledge of materials sciences, photonic, and biointerfaces for label-free, ultra-sensitive, and selective assays to enable future drug and diagnostics target discovery.
