Visualization of Dynamic Processes with Video-Rate Atomic Force Microscopy — •Ted Limpoco, Mario Viani, and Marta Kocun — Asylum Research, an Oxford Instruments company, 6310 Hollister Ave, Goleta, U.S.A.

Atomic Force Microscopy (AFM) is a unique and powerful tool for measuring structural, mechanical, and electrical properties of materials at the nanometer scale. A limitation of conventional AFM is that it is a slow technique, with image acquisition times on the order of minutes. The recent introduction of a practical video-rate AFM has improved imaging speeds and makes it now possible to capture movies with a temporal resolution better than a second. This presentation will cover some recent results taken via video-rate AFM, including the real-time self-assembly of collagen into fibrils and the migration of surfactant micelles on graphite. Additionally, we will discuss related results such as the melting/re-crystallization of polymers and consider future research opportunities that might be enabled by this technology.
