Event details

Part of the Electrochemistry Group Seminar Series

Scanning ion conductance microscopy (SICM) was invented by Paul Hansma at the University of Santa Barbara in 1989 (Hansma et al., 1989) and is a form of Scanning Probe Microscopy technique that uses glass pipette filled with electrolyte as an imaging probe to generate topographical images of surfaces. In 1997 SICM was modified and made applicable to nanoscale imaging of live biological cells by Yuri Korchev (Korchev et al., 1997;Korchev et al., 1997). Subsequent advances in SICM which include improved topographical resolution (Shevchuk et al., 2006) and the invention of “hopping probe ion conductance microscopy” (HPICM) (Novak et al., 2009) has brought the quality of SICM imaging to levels comparable with scanning electron microscopy whilst retaining live-cell imaging capabilities. Recently, we have solved the problem of measurement-independent probe-sample distance regulation, the vital missing component in scanning electrochemical microscopy (SECM) since its invention in 1989. This was achieved by combining SICM and SECM for simultaneous SICM-SECM imaging (Takahashi et al., 2010;Takahashi et al., 2011).
