In both the video-rate AFM and ultra-high speed kilohertzAFM imaging, no discernible damage to the collagen specimenoccurred after tens of thousands of frames. This is clearly asignificant phenomenon for not only high-speed AFM but alsofor nanoscale mechanical systems operating in a high-shearrateregime. Evidence from preliminary investigations of thisphenomenon point to a super lubricity effect associated withthin layers of water confined between the scanning probe andthe specimen. These studies will be presented in a separatepublication
