A method, apparatus and product for producing an advantaged cell growth surface. According to the present invention, a stream of plasma is comprised of activated gaseous species generated by a microwave source (10). This stream is directed at the surface of a polymer substrate (26) in a controlled fashion such that the surface is imparted with attributes for cell adhesion far superior to that of untreated polymer or polymer treated by other known methods.
L'invention concerne un procédé, un appareil et un produit permettant de produire une surface de croissance cellulaire avantageuse. Selon l'invention, un flux de plasma est constitué d'espèces gazeuses activées, produites par une source micro-ondes (10). Ce flux est dirigé sur la surface d'un substrat polymère (26), de manière régulée, de sorte à conférer à ladite surface des propriétés d'adhérence des cellules nettement supérieures à celles d'un polymère non traité ou traité selon d'autres procédés connus.
