Medgadget -- Gavin King, a physicist out of University of Missouri, together with Allison Churnside and Thomas Perkins from Department of Molecular, Cellular, and Developmental Biology at the University of Colorado at Boulder, have published an interesting paper in SPIE that takes a look at the future of scanning-probe microscopes, and possible ways to overcome some of the problems that are still not resolved in this technology. Scanning Probe Microscopy (SPM) obtains an image of the surface by mechanically moving a probe, but it suffers from intrinsic mechanical drift. The authors believe they can overcome this detrimental effect that occurs between the scanning-probe tip and sample with some quantum trickery.
