Abstract
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. 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 far superior to that of untreated polymer or polymer treated by other known methods.
Claims13
An apparatus for treating a polymeric substrate surface comprising:
- a) a gas inlet, a microwave energy source and a plasma mixing chamber, the plasma mixing chamber in fluid communication with both the gas inlet and the microwave energy source;
- b) a dual chambered treatment area having an inner treatment chamber contained within an outer treatment chamber, said inner treatment chamber having an opening in fluid communication with said outer chamber;
- c) said plasma mixing chamber in fluid communication with said outer treatment chamber by means of an aperture;
- d) a vacuum outlet line attached to said outer chamber;
- and
- e) whereby said opening in said inner treatment chamber is aligned with said aperture, said opening being spaced from said aperture a predetermined distance.
