Introduction

Gas plasma technology is a process commonly used for treating surfaces prior to surface modification. It can be used for precision cleaning and activatation, decontamination of surfaces, to promote adhesion of functional bio-molecules and in conjunction with specific chemical vapors to sterilize in-vivo and in-vitro medical devices.

Research and Development

The development of cellular and bio-molecular isolation and analysis technologies dictates how fast research and discovery in the biological science areas advances. Plasma surface modification is used in products and platforms such as immunoassays, cell culture media, filtration and analyte delivery devices to enable selective bio-molecular immobilization and to avoid surface effects due to miniaturization.

Microfluidic Devices

Plasma treatment is of great benefit to recently developed micofluidic devices which are used in drug discovery, diagnostics, medical device and drug delivery. In these devices, the channels are made more wettable improving flow and dispensing which is of importance as the channels are extremely narrow.

Medical Devices

The surfaces of medical devices that come into contact with physiological environments such as those encountered in the human body can be modified to induce more favorable interactio. Medical devices can be engineered to illict responses such as anti-fouling, anti-microbial, anti-thrombogenic etc. using gas plasma processes. The process may involve tailoring surfaces using specific chemistries which act as a bio-molecule tie layer.
