Mapping real-time images of high-speed AFM using multitouch control

摘要

Conventional AFM is highly restricted by its scan rate, a problem that has been overcome bythe development of high-speed AFM systems. As the technology to produce higher scan rateshas developed it has pushed forward the design of control software. However, the user interfacehas not evolved at the same rate, limiting the user to sequential control steps. In this paper wedemonstrate the integration of HSAFM with a multitouch interface to produce a highly intuitiveand responsive control environment. This enables nanometre resolution to be maintained whilstscanning the sample over tens of microns, and arbitrary paths to be traversed. We illustrate thisby scanning around two chromosomes in water, before scanning on top of the chromosome,showing the surface structure.
