Combined microscopy technique catches light-driven polymers in the act

Researchers combine high-speed atomic force microscopy with a laser light source for real-time observation of azo-polymer films

13-Mar-2024 - Expanding our scientific understanding often comes down to getting as close a look as possible at what is happening. Now researchers from Japan have observed the nanoscale behavior of azo-polymer films while triggering them with laser light. In a study published last month in Nano Letters the ...

Three-dimensional Direction-dependent Force Measurement at the Subatomic Scale

15-May-2017 - Atomic force microscopy (AFM) is an extremely sensitive technique that allows us to image materials and/or characterize their physical properties on the atomic scale by sensing the force above material surfaces using a precisely controlled tip. However, conventional AFM only provides the surface ...
