Gold nanoparticles have great potential in biomedical applications because of their biocompatibility, accessibility, chemical functionality and unique optical properties arising from surface plasmon resonance. Plasmon resonance can confine light into a nanoscale volume, resulting in a local enhancement of electric field. This plasmon-mediated concentration of the electric field in the vicinity of metallic nanostructures can lead to enhanced luminescence, energy transfer and even lasing processes. This project aims to understand light-nanomaterial interactions in hybrid plasmonic systems and develop novel noble metal nanostructures for enhanced performance for biomedical sensing. This is a multidisciplinary project, involving state-of-the-art optical spectroscopy and nanofabrication at the interface of nanotechnology and healthcare.
