Coating Technologies

Multiple application methods — optimized per device

We utilize a variety of coating technologies to formulate the best coating process for each type of medical device, taking into consideration the device geometries, coating quality, process scalability and robustness.

Plasma treatment

Surface activation and cleaning for improved adhesion of subsequent coatings.

Plasma polymerization

Core PECVD process for covalently-bound functional polymer coatings.

CVD / PECVD

Chemical and plasma-enhanced vapor deposition for conformal thin films.

Dip coating

Controlled immersion for uniform coating application on simple geometries.

Spray coating

Atomized application for large surfaces and complex component assemblies.

Spin coating

High-uniformity application for flat and near-flat substrate surfaces.

Core Technology

Plasma Assisted Polymer Coatings (PECVD)

We use a proprietary plasma assisted polymer coating technology (plasma polymerization, PECVD) that produces highly customized, fully functional surfaces for a variety of applications. This innovative process uses the fourth state of matter (plasma) to create a polymer coating on the surface of various materials, resulting in pinhole free and complete device coverage.

The resulting polymer coatings are customized for individual applications to produce the desired surface characteristics. Polymer surfaces created with the Medical Surface coating technology are:

Covalently Bound — molecular-level bonding to the substrate surface, resisting delamination under mechanical stress
Biologically inert and non-degradable — stable in physiological environments for the duration of device use
Noncytotoxic — safe for contact with living cells and tissues
Plasma PECVD coating technology

Polymer Engineering

Polymer/Hydrogel Engineering Tailored for Specific Applications

The polymer/hydrogel coating can be functionalized by adding reactive functional groups to the surface. This provides a superior, low background surface for immobilizing enzymes, antibodies and other biomolecules.

Surface properties that can be engineered include:

Hydrophilicity
Surface charges
Protein resistance
Permeability control
Polymer and hydrogel engineering

Polymer/hydrogel surface functionalization

Surface Functionalization

Functionalized Surface Coatings for Biosensor Applications

Our innovative process allows for the engineering of the polymer/hydrogel coating, which results in different combinations of surface properties optimized for specific applications. Examples of functional groups covalently linked to the coating include:

NHS group for amine immobilization
Maleimide group for thiol immobilization
Biotin group for streptavidin immobilization
Ni-NTA group for poly-histidine immobilization
Protein A for antibody immobilization
Peptides for specific bindings
Antibodies for antigen binding/assays
ECM proteins for cell attachment
