Recent advances in electrochemistry by scanning electrochemical microscopy

The review briefly presents the principle and instrumentation of SECM. Then we focus on the application of SECM in several areas such as charge transfer, solar cells, imaging, bioanalysis in recent years. SECM can capture real time (electro)chemical information at a micro interface which helps us to explore the microscopic world. SECM is also employed to investigate the complicated electron transfer system and biosamples. Last seven years literature infers SECM is a comprehensive characterization tool when it is combined with other techniques.
