Poly(l-lysine)-graft-poly(ethylene glycol) Assembled Monolayers on Niobium Oxide Surfaces: A Quantitative Study of the Influence of Polymer Interfacial Architecture on Resistance to Protein Adsorption by ToF-SIMS and in Situ OWLS
TL;DR: In this article, a set of poly(l-lysine) grafted with poly(ethylene glycol) (PLL-g-PEG), a polycationic copolymer that is positively charged at neutral pH, spontaneously adsorbs from aqueous solution onto negatively charged surfaces.
Journal ArticleDOI
Influence of PEG architecture on protein adsorption and conformation.
TL;DR: Poly(L-lysine)-g-poly(ethylene glycol) (PLL-g-PEG) copolymers with various grafting ratios were adsorbed to niobium pentoxide-coated silicon wafers and characterized before and after protein adsorption using X-ray photoelectron spectroscopy and time-of-flight secondary ion mass spectrometry.
Journal ArticleDOI
Effects of ionic strength and surface charge on protein adsorption at PEGylated surfaces.
TL;DR: The combination of AFM surface force measurements and protein adsorption experiments provides insights into the interfacial forces associated with various PEGylated surfaces and the mechanisms of protein resistance.
Journal ArticleDOI

TL;DR: In this paper, the application of poly(L-lysine)-g-poly(ethylene glycol) (PLL-g-PEG) as an additive to improve the lubricating properties of water for metal-oxide-based tribo-systems was explored.
Journal ArticleDOI
Relationship between interfacial forces measured by colloid-probe atomic force microscopy and protein resistance of poly(ethylene glycol)-grafted poly(L-lysine) adlayers on niobia surfaces.
TL;DR: The data demonstrate the importance of an ionic-strength-dependent minimum PEG layer thickness to screen the electrostatic interactions of charged interfaces and to advance interpretation of protein adsorption or repellence beyond the oversimplified steric barrier model.
