Gas plasma technology is commonly used to precision
clean and activate, decontaminate surfaces,
promote adhesion of functional bio-molecules and
in conjunction with specific chemical vapors sterilize
in-vivo and in-vitro medical devices.
PLASMA SURFACE TREATMENT OF BIOMATERIALS
Acceleration of research and discovery in the biological
science areas rely on advancing technologies
cellular, and bio-molecular isolation.
Products and platforms such as tissue scaffolds, immunoassays,
cell culture media, filtration and analyte delivery
devices require plasma surface modification to
enable selective bio-molecular immobilization and
to avoid surface effects due to miniaturization.
Newly developed micro-fluidic platforms used
throughout multiple industries including the life
science fields of drug discovery, diagnostics, medical
device and drug delivery are significantly enhanced
with plasma treatment. Micro-channels on
clinical diagnostic devices are made “wettable” to
fluids improving both flow and dispensing.
Surfaces that come in contact with biological environments
such as the human body can be engineered
to elicit specific biological responses, e.g.
anti-fouling, anti-microbial, anti-thrombogenic etc.
This can be achieved by direct use of plasma produced
surfaces. Alternately plasma can be used to
tailor surface chemistries with specific functional
groups to act as a defined bio-molecule tie layer.
