title: Improving the electrochemical imaging sensitivity of scanning electrochemical microscopy-scanning ion conductance microscopy by using electrochemical Pt deposition.
abstract: We fabricated a platinum-based double barrel probe for scanning electrochemical microscopy-scanning ion conductance microscopy (SECM-SICM) by electrodepositing platinum onto the carbon nanoelectrode of the double barrel probe. The deposition conditions were optimized to attain highly sensitive electrochemical measurements and imaging. Simultaneous SECM-SICM imaging of electrochemical features and noncontact topography by using the optimized probe afforded high-resolution images of epidermal growth factor receptors (EGFR) on the membrane surface of the A431 cells.
