Abstract:Microdevices composed of microwell arrays integrating nanoelectrodes (OptoElecWell) are developed to achieve dual high‐resolution optical and electrochemical detections on single Saccharomyces cerevisiae yeast cells. Each array consists of 1.6 × 105 microwells measuring 8 µm in diameter and 5 µm height, with a platinum nanoring electrode for in situ electrochemistry, all integrated on a transparent thin wafer for further high‐resolution live‐cell imaging. After optimizing the filling rate, 32% of cells are eff… Show more
