Atomic Force Microscope Measuring in Liquid and its Applications
液相型原子力显微镜的研制及其应用

A new type of AFM measuring in liquid is developed for applications in nanotechnology field. This article introduces the structure of the AFM probe, liquid cell, photoelectronic feedback control system and the software for image scanning and processing in liquid. By using the AFM measuring in liquid, images of some samples were successfully gained in liquid and air,respectively. Experiments show that the AFM measuring in liquid is of reliable stability,good repeatability,high resolution and high performance on image scanning in liquid.
