Oxygen plasma functionalization of parylene C coating for implants surface : Nanotopography and active sites for drug anchoring
TL;DR: The obtained results clearly show that the plasma treatment of parylene C surface provides suitable polar groups (C=O, C-O, O-C =O,C-O-O and O-O(O)-O) for further development of the coating functionality.

Poly (vinyl alcohol)/gum karaya electrospun plasma treated membrane for the removal of nanoparticles (Au, Ag, Pt, CuO and Fe3O4) from aqueous solutions
Vinod V.T. Padil,Miroslav Černík +1 more
TL;DR: Physisorption, functional group interactions, complexation reactions between metal/metal oxide nanoparticles with various functional groups present in NFM and modified surface properties such as the balance of hydrophilicity/hydrophobicity, surface free energy, and the high surface area of the plasma treated membrane were possible mechanisms of NPs adsorption onto NFM.

Surface characterization and in vitro blood compatibility of poly(ethylene terephthalate) immobilized with insulin and/or heparin using plasma glow discharge.
TL;DR: The blood compatibilities of the surface-modified PETs were examined using in vitro thrombus formation, plasma recalcification time (PRT), activated partial thromboplastin time (APTT), and platelet adhesion and activation, suggesting the binding of immobilized heparin to antithrombin III.

Surface modification of polyester by oxygen- and nitrogen-plasma treatment
TL;DR: In this paper, the surface modification of polyethyleneterephthalate (PET) polymer by plasma treatment was studied and the changes in surface morphology were observed by using atomic force microscopy (AFM).

Treatment of polymer films with a dielectric barrier discharge in air, helium and argon at medium pressure
TL;DR: In this article, polyester (PET) and polypropylene (PP) films are modified by a dielectric barrier discharge in air, helium and argon at medium pressure (5.0 Ã 0 Ã kPa), and the plasma-modified surfaces are characterized by contact angle measurements and X-ray photoelectron spectroscopy (XPS) as a function of energy density.

Improved endothelialization of vascular grafts by local release of growth factor from heparinized collagen matrices
M.J.B Wissink,R. Beernink,A.A. Poot,Gerard H.M. Engbers,Tom Beugeling,W.G. van Aken,Jan Feijen +6 more
TL;DR: In this article, the influence of immobilization of heparin to collagen, crosslinked using N-(3-dimethylaminopropyl)-N′-ethylcarbodiimide (EDC) in combination with N-hydroxysuccinimides (NHS), on the binding and release of bFGF was determined.

Use of plasma glow for surface-engineering biomolecules to enhance bloodcompatibility of Dacron and PTFE vascular prosthesis.
TL;DR: It is proposed that surface grafting of matrix components (collagen-type IV and laminin) and subsequent immobilization of bioactive molecules (PGE1, heparin or phosphatidyl choline) changed the surface conditioning of vascular grafts and subsequently improved their biocompatibility.
