Paper Abstract

Surface potential measurement on organic thin films and isolated biological samples have been performed using a scanning Maxwell-stress microscopy (SMM). The SMM is a type of scanning probe microscopy designed to image microscopic electrical properties, such as the local surface potential distribution. The present microscope afforded information of the lateral distribution of molecular dipole moments in phase separated monolayer, and the topographic image of purple membrane fragments as well as dielectric properties of samples.
