The Life Science and Medical industry have seen a great deal of innovation in recent years. The present day advances in research, manufacturing, distribution and market acceptance of new and existing products have been very exciting. Gas Plasma technology has played a variety of roles in this scope of innovative work. These roles vary widely depending on the product market application. However, they do fall into the four categories of plasma cleaning, plasma activation, plasma etching, and plasma coating.
Plasma cleaning of a surface is a reliable way to remove manufacturing residue, foreign materials and bio-burden from a surface. The process of plasma cleaning parts with Gas Plasma is a repeatable method of dealing with your unwanted residue.
Plasma activation of a surface is performed in conjunction with cleaning. Prior to cleaning a surface with Gas Plasma, a surface can be transitioned to a phase of increased activation. The process of increasing activation energy of a surface is often used to promote a liquid wetting of the surface. This liquid could be fluid used in a micro fluidic application or an adhesive in preparation for assembly.
Etching a surface with Gas Plasma can be used to perform different functions. Gas Plasma etching is often used when the highest level of bonding adhesion strength is required. By etching a surface to base material and opening bond sights in a material on a molecular level provides an opportunity for some of the highest bond strengths possible. Gas Plasma etching is also used to remove and pattern material in a bulk or selective manner in a product design. The process of Gas Plasma etching is able to produce structures and features that would not be able to be produced by any other manufacturing method.
Coating or performing a deposition process utilizing Gas Plasma provides the opportunity to change the surface of a part drastically and optimize the surface performance for your application. Whether you are trying to make a contact lens wet or to alter the surface chemistry to define a bio-molecular tie layer, Gas Plasma coating is able to manipulate a surface in a manner paralleled by no other manufacturing process available today.
