SECM-SICM has also been used to explore the permeation property of a cell membrane, in particular that of a cardiac myocyte [125]. Using hopping mode SICM, it was possible to record the topography of an individual heart cell, which was revealed to exceed 20 pm in height. Current profiles were recorded for oxygen, Fe(CN). and FCCH2OH as the SECM-SICM probe approached the cell surface. The probe was then moved laterally to the next position in the line scan and the
