Scanning Ion Conductance Microscopy (SICM) is a state-of-the-art nanometre imaging system. Its main application is to acquire topographic images of surfaces in electrolyte solutions. Images are created by scanning a (glass or quartz) nanopipette probe over the sample whilst measuring the ion current through the pipette. As the probe approaches the sample surface the ion current decreases. This unique feedback mechanism allows the nanopipette to avoid physical contact with the sample – meaning that SICM is particularly well suited for imaging soft samples such as live cells. 

SICM can be integrated with multiple techniques including recording of Young's Modulus surface, targeted patch-clamp, confocal microscopy, optical mapping, localized pharmacological application, or Forster Resonance Energy Transfer (FRET), among others.
