Abstract
A method of producing an improved cell growth surface and cell attachment surface. According to the present invention, a polymer article is molded at temperature in excess of 550° F. at the injection tip. After allowing the part to cool, a stream of plasma comprised of activated gaseous species generated by a microwave source is imparted on the article. This stream is directed at the surface of a polymer substrate in a controlled fashion such that the surface is imparted with attributes for cell adhesion superior to those of untreated polymer or polymer treated by other methods.
