Time-gated detection microscopy will give these nanophosphors a superior optical contrast. The nanophosphors’ antibody-targeting will image single AMPA membrane receptors in their full biological context, crucial to understanding neuronal signalling. Simultaneous imaging of receptor trafficking and activity in neurons will help to uncover details of the dynamic activity in the brain. This technology is expected to help understand the inner workings of the brain and provide insights into its functioning.Read moreRead less

By developing fluorescence pattern-based 3D motion-detection technology in optical tweezers, this project aims to reveal how to achieve nanoscale laser cooling in physiological media. It plans to discover new mechanisms of cooling associated with surface phonons and energy looping in optically trapped lanthanide-doped nanoparticles. Key expected outcomes are technology and a toolset to create interaction between cooled nanoscale objects and biological samples.

This project aims to develop a routine methodology capable of extracting precise information from single DNA molecules by incorporating plasmonic components into a lab-on-a-chip device for use under conventional optical microscopes. The configuration would have the convenience and technological maturity associated with microscopes whilst being able to capture details of biomolecules with unprecedented detail. New DNA analyses will be made possible by the platform, such as studying the genomic diversity within a population of tumour cells.Read moreRead less
