Title: Transforming Surface Plasmon Resonance into Mobile BiosensingTechnology via Advanced Nanoplasmonic Devices
Abstract: Surface plasmon resonance (SPR) sensing is a powerful label freebiomolecular detection technique used for drug screening, proteincharacterization, enzymatic kinetics studies and living cell membraneimaging. However special expensiveoptical spectroscopy equipment and systems are required for SPR sensing andimaging and they are not available in most research laboratories. In my talk, I will present our work ondeveloping colorimetric and photonic resonator integrated nanoplasmonicresonance devices. Our colorimetric nano Lycurgus Cup Array (nanoLCA) sensor isthe first colorimetric SPR sensor device (not based on colloidal nanoparticles)ever reported with a record high sensitivity so that the molecular and liquid SPRsensing can be visualized as transmitted or reflected color changes by colorcamera, photodiode or even naked eyes. With such a unique nanoplasmonic device,SPR biomolecular sensing and imaging is enabled on most ubiquitous instrumentssuch as bright-field microscope, microplate reader and smartphones. I will showthe label-free colorimetric and intensity-based nanoplasmonic sensing andimaging of DNA hybridization, cancer biomarker protein binding kinetics anddrug metabolisms. I will also discussabout the nanoplasmon enhanced colorimetric bioassay applications.
