A Liquid contact angles on biocompatible surfaces

Abstract

Measurements of liquid contact angles on biocompatible surfaces have been performed at the Physics Department of Messina University. Biological solutions, polymers, ceramics and metals have been studied. Surface treatments by using different laser irradiations, depending on the laser intensity and wavelength, permit to change drastically the wet-ability of many materials and to enhance their biocompatibility and functionality. Results of our investigations put in evidence the best materials to increase or to reduce the wetability of the biological liquids. Results will be presented and discussed in detail with special regard to their applications in biological environment where the materials can be embedded.
