Abstract: A solid surface wettability determination method is disclosed. A liquid is sprayed on a surface of an object. A light beam is projected toward the surface, wherein the light beam is reflected by the liquid on the surface to generate a reflected light. The reflected light is received by an optical detector, and the optical detector outputs a determining signal related to a wettability of the surface according to the reflected light. A corresponding signal-angle relation is selected from a database according to type of the liquid and material of the object. The contact angle of the liquid on the surface is obtained by applying the determining signal to the corresponding signal-angle relation.

Abstract: A method for drug screening is provided. An atomic force microscopy (AFM) is used to obtain quantitative difference. At least one receptor is immobilized on a probe of the AFM and at least one ligand is immobilized on chips. By flowing a candidate drug on the chips or even applying different candidate drugs to different areas of each chip, drug screening is processed through measuring the binding force between the receptor and the ligand. Multiple drugs can be screened without weakening activity of the proteins during repeated drug screening processes. The drug screening process is cost saved and has high quality. Highly effective protein chips can be developed based on the present disclosure.
