摘要：

Continued advances in life science and technologies require new imaging capabilities. In this talk, a novel imaging approach based on surface plasmon resonance will be described. Compared to the traditional optical imaging techniques, the plasmonic-based approach can image not only the morphology of samples, but also local electrochemical current and impedance of various chemical and biological processes. Important benefits of this approach include fast and non-invasive electrochemical current and impedance imaging of various samples. Using the techniques, various applications, including sensitive and selective trace analysis, protein microarrays, and single cell studies, have been demonstrated.
