Novel Probe-Sharpening Technique Enhances Microscope Resolution

Researchers led by Professor Joseph Lyding at the University of Illinois have devised a new technique to sharpen microscopic probes that significantly enhances image resolution. Probes are essential components of microscopes widely used to study structures of atomic scale where the tip of the probe is used to scan the sample surface to determine its chemical, electrical and mechanical properties.

AFM Probes Sans Gold Coating Provide Stable Measurement of Picoscale Forces

Atomic Force Microscopes (AFM) are normally coated with gold to improve reflection of light. Researchers at JILA, the joint institute of National Institute of Standards and Technology (NIST) and the University of Colorado Boulder, stripped off the gold coating from the probe and found that stability and precision of measurements carried out in a liquid improved ten-fold. Liquid is the preferred medium for measurement in the field of biophysics where cells and DNA are kept immersed in liquid to replicate their natural environs.
