The researchers from the Netherlands presents a new concept to induce macroscopic morphing in polymer surfaces by an amplified response of a single molecule event. The kinetics of the surface deformation is measured by DHM

We are making surface structures can be switched ‘on’ and ‘off’ by external means (at the frequency ranging from several Hertz to hundred Hertz. Digital Holographic Microscope (DHM) has the unique possibility to measure real-time 3D topography in a non-contact and non-scanning manner while keeps the vertical resolution to sub-nanometers
