通过溶剂热法将壳聚糖衍生的碳量子点（CD）共价连接到氧化铟锡（ITO）表面，并显示出直接的光电化学响应，ITO-硅烷-CD表面的光电流归因于CD在光照下的光生电子转移过程。ITO-硅烷-CD表面被成功地用于交流光电流成像。这为CD在生物成像应用中作为生物相容性和光寻址电化学传感器开辟了新的应用。
Carbon dots (CDs) derived from chitosan via a solvothermal method were covalentlylinked to an indium tin oxide (ITO) surface and showed a direct photoelectrochemical response.We attribute the photocurrent of the ITO-silane-CD surface to a photogenerated electron-transferprocess by CDs under illumination. The ITO-silane-CD surface was successfully used forac-photocurrent imaging. This opens up new applications for CDs as biocompatible andlight-addressable electrochemical sensors in bioimaging applications.
