WebbScanning probe microscopy or SPM is a microscopy technique that produces images by scanning the specimen with the help of a probe, capable of measuring small local differences in the height of the specific sample material with out being impacted by diffraction. These microscopes are able to carry out the imaging of several interactions … Webb6 feb. 2012 · When a micrometer-scale scanning probe tip is near a voltage biased nanometer-scale pore (10-100 nm), the tip partially blocks the flow of ions to the pore and increases the pore access resistance. The apparatus records the current blockage caused by the probe tip and the location of the tip simultaneously.
