Efficient Modelling and Optimisation of Advanced Nano-Plasmonic Optical Biosensors and Markers

A collaboration between Cardiff University and Swansea University







Different resonant states’ contributions to the perturbed resonant state.







This project employs a novel theoretical method in electrodynamics which we have recently invented and verified. It will allow us to produce a fast and accurate computational tool to predict, design and optimise the properties of nano-plasmonic particles, paving the way for their development, fabrication and use in biotechnology applications.

Resonant optical biosensors have recently become an important tool for bioscience research and drug discovery. They cover a range of applications going from the detection of toxins, proteins, DNA and infectious agents to the investigation of whole cell behaviour and quantitative determination of binding affinities and interaction kinetics between proteins or other biomolecules




The aim of this proposal is to develop an efficient modelling technique for quantitative description, analysis, and optimization of advanced intracellular biosensors and markers for research and therapy based on optical resonances of metal nanoparticles.
