Abstract: Gas plasma is a powerful method for molecular reengineering of materials to impart unique surface properties, without affecting the bulk properties. The technology is a critical tool for the life sciences industry. Applications include but are not limited to: atomic level cleaning; incorporation of functional species for diagnostic and research tools; deposition of nanometer scale thin film organic coatings to change lubricity, permeation or chemical resistance on devices; and creation of interfacial surfaces for primerless adhesion and overmolding. The effect of plasma on a material is determined by the chemistry of the reactions between the surface and the reactive species present in the process gas employed One tool may be used for myriad applications as it is easily configured with several gases. Each gas produces a unique plasma composition resulting in different surface properties. Liquids may also be introduced as vapors, expanding by many orders of magnitude the potential for unique surface alterations and coatings. The presentation will provide an overview of the diverse plasma processes applied to materials for life science applications. Discussions will include surface stability, surface validation, and a review of common study variables.
