Photoelectrochemical Imaging Using Carbon Dots (CDs) Derived from Chitosan
Carbon dots (CDs) derived from chitosan via a solvothermal method were covalently<br />linked to an indium tin oxide (ITO) surface and showed a direct photoelectrochemical response.<br />We attribute the photocurrent of the ITO-silane-CD surface to a photogenerated electron-transfer<b...

description | Carbon dots (CDs) derived from chitosan via a solvothermal method were covalently<br />linked to an indium tin oxide (ITO) surface and showed a direct photoelectrochemical response.<br />We attribute the photocurrent of the ITO-silane-CD surface to a photogenerated electron-transfer<br />process by CDs under illumination. The ITO-silane-CD surface was successfully used for<br />ac-photocurrent imaging. This opens up new applications for CDs as biocompatible and<br />light-addressable electrochemical sensors in bioimaging applications. |
