Title:
“Empowering functional biomedical imaging and spectroscopy with nanophotonics”

Abstract:
Nanophotonics has emerged as a major technology and applications domain, exploiting the interaction between light and nanometer-scale objects with the goal to gain ultimate control over all properties of light. Recently, innovations in photonic materials and instrumentation have led to high-performance optical imaging and single molecule detection through dramatically increased sensitivity and specificity. In this seminar, I will introduce two examples reflecting my adventure in bridging nanophotonics and biological imaging to gain the enhanced capability of functional biomedical imaging and spectroscopy. Firstly, I will discuss the development of a unique optical ultrasonic sensor based on a polymeric micro-ring resonator, which enables extremely high sensitivity, ultra-broad bandwidth, and wider angular sensitivity, satisfying the high demands of ultrasonic sensing in high-resolution functional photoacoustic microscopy. Secondly, I’ll introduce a wide-field spectroscopic nanoscopic imaging technology, called spectroscopic photon localization microscopy, which is capable of simultaneously capturing the spatial distributions of photons emitted by individual molecules with nanometer accuracy and their inherent spectroscopic signatures with sub-nm spectral resolution. By overcoming the diffraction barrier of analytical imaging methods, the new resolving capability can potentially provide new insights into biological processes and bring about significant research progress in the life sciences.
