This project aims to enhance the sensitivity of optical activity to ultralow molecular concentration samples. Optical activity is a commercially available technique used to distinguish chemically identical and morphologically different biomolecules (enantiomers). Unlike other scattering techniques, near-field enhancing of optical activity has not been achieved, thus limiting these measurements to high molecular concentrations. There is evidence indicating that optical activity can be enhanced using dual nanoparticles (ie small particles with the same response to electric and magnetic fields). This project aims to advance our understanding of these dual nanoparticles and experimentally implement their use to enhance optical activity.Read moreRead less

The emergence of flexible nanoelectronics holds the promise to impact the way we live—from smart wearables to foldable smartphones. However, heat dissipation in the atomically-thin materials used for their conception has remained poorly understood due to their planar structures. This project aims at the detection and mapping of nanoscale thermal hotspots in flexible nanoelectronics devices using a two-dimensional-based optical thermometer. The expected outcome of this project is the development of a non-invasive thermometric technology that enables locating these critical nanoscale hotspots with nanoscale precision. This will lead to better design and manufacturing strategies for heat dissipation in these devices.Read moreRead less
