Surface properties of biomaterials can easily be modified by glow-discharge plasma processing for very diverse biomedical applications. Activated carbon granules can be coated with a very thin polymeric membrane by plasma polymerization to improve their blood compatibilities without changing their adsorption capabilities. The problems associated with the microporous polypropylene oxygenator membranes can be eliminated by coating with a nonporous thin polymeric film in a glow-discharge reactor. Cell attachment and growth on polystyrene microcarriers can significantly be increased by alkylamine plasma treatment. Physical and chemical properties of polyurethane biomaterials can be tailor-made by plasma modification.
生物材料的表面特性可通过辉光放电等离子体处理轻松改变，以用于非常多样的生物医学应用。通过等离子体聚合，可在活性炭颗粒上涂覆一层非常薄的聚合物膜，以提高其血液相容性，同时不改变其吸附能力。在辉光放电反应器中用无孔聚合物薄膜进行涂覆，可消除与微孔聚丙烯充氧膜相关的问题。通过烷基胺等离子体处理，可显著增加细胞在聚苯乙烯微载体上的附着和生长。聚氨酯生物材料的物理和化学性质可通过等离子体改性进行定制。
