Scanning electrochemical microscopy (SECM) is coupled with surface-enhanced Raman scattering (SERS) microscopy to characterize local surface modifications. SECM is utilized for the surface patterning of para-nitrothiophenol self-assembled monolayers (SAMs) in the direct mode of SECM with a subsequent readout of the chemical patterns by means of combined SECM-SERS. The SECM-SERS combination allows monitoring of local electrochemical processes and provides simultaneous complementary spectroscopic information. The reaction products upon SAM reduction, specifically p-aminothiophenol groups, are distinguished from the pristine SAM and locally ruptured areas.

通过结合扫描电化学显微镜和表面增强拉曼散射研究局部表面修饰。

扫描电化学显微镜（SECM）与表面增强拉曼散射（SERS）显微镜相结合，以表征局部表面修饰。SECM以SECM的直接模式用于对硝基硝基苯酚自组装单层（SAMs）的表面图案化，随后通过结合的SECM-SERS读出化学图案。SECM-SERS组合可监控局部电化学过程并提供同时的互补光谱信息。SAM还原后的反应产物，特别是对氨基硫酚基团，与原始的SAM和局部破裂的区域不同。
