Nongjian (NJ) Tao, a senior sustainability scientist and director of The Center for Bioelectronics and Biosensors in the Biodesign Institute, is a winner of the Fourth Annual Innovation Award from Microscopy Today. Tao developed the technique he calls Plasmonic-Based Electrochemical Microscopy, or P-ECM, that identifies local chemical reactions of individual nanoparticles. The method increases speed of imaging, is non-invasive, and could be used in drug and vaccine development. "While many people are pushing the spatial resolution of microscopy, we are interested in creating new capabilities to image local chemical reactions at extremely fast time scales," Tao says. "I am glad this effort has been recognized."
