Whole blood coagulation on protein adsorption-resistant PEG and peptide functionalised PEG-coated titanium surfaces.
The aim of this study was to investigate whole blood coagulation on low blood plasma protein adsorbing surfaces. For this purpose, the polycationic graft copolymer poly(L-lysine)-g-poly(ethylene glycol) (PLL-g-PEG), PLL-g-PEG grafted with a cell adhesive peptide containing the amino acid sequence -Arg-Gly-Asp- (RGD), and PLL-g-PEG with a control peptide -Arg-Asp-Gly- (RDG) were adsorbed onto ti...
متن کاملQCM-D Study on Relationship of PEG Coated Stainless Steel Surfaces to Protein Resistance
Nonspecific protein adsorption generally occurs on any solid surfaces and usually has adverse consequences. Adsorption of proteins onto a solid surface is believed to be the initial and controlling step in biofouling. Surfaces modified with end-tethered poly(ethylene glycol) (PEG) have been shown to be protein-resistant to some degree. In this study, the adsorption of β-casein and lysozyme was ...
متن کاملProteins and cells on PEG immobilized silicon surfaces.
Silicon surfaces were modified by covalent attachment of a self-assembled (SA) polyethylene glycol (PEG) film. Adsorption of albumin, fibrinogen, and IgG to PEG immobilized silicon surfaces was studied by ellipsometry to evaluate the non-fouling and non-immunogenic properties of the surfaces. The adhesion and proliferation of human fibroblast and Hela cells onto the modified surfaces were inves...
متن کاملImpact of PEG and PEG-b-PAGE modified PLGA on nanoparticle formation, protein loading and release.
The effect of modifying the well-established pharmaceutical polymer PLGA by different PEG-containing block-copolymers on the preparation of ovalbumin (OVA) loaded PLGA nanoparticles (NPs) was studied. The used polymers contained poly(d,l-lactic-co-glycolic acid) (PLGA), polyethylene glycol (PEG) and poly(allyl glycidyl ether) (PAGE) as building blocks. The double emulsion technique yielded sphe...
متن کاملTo PEG or not to PEG.
Patients with adequate intestinal function who are unable to eat may benefit from enteral tube feeding. Percutaneous endoscopic gastrostomy (PEG) is preferred when prolonged treatment is envisaged. PEG feeding will reduce morbidity and mortality in many such patients by reversing malnutrition. The increasing numbers of elderly patients with chronic diseases have resulted in an increased demand ...
