Lowtemperature plasma techniques in surface modification of biomaterials

Since synthetic polymers usually can not meet the biocompatibility and biofunctional demands of the human body, surface treatment is a prerequisite for them to be used as biomaterials. A very effective surface modification method, plasma treatment, is introduced in this paper. By immobilizing the bioactive molecules with low temperature plasma, polymer surfaces can be modified to fully satisfy the requirements of biomaterials.
