TL;DR: In this paper, a simple model based on free volume theory is used to correlate a wide range of CO 2 permeability coefficients in PEO containing materials, and the results are satisfactory, particularly given the simplicity of the model.

TL;DR: In this article, the authors describe the preparation of oligo(ethylene glycol)-terminated alkanethiols having structure HS- (CHz)'l(OCH2CHz),nOH (m = 3-7) and their use in the formation of self-assembled monolayers (SAMs) on gold.
Abstract: This paper describes the preparation of oligo(ethylene glycol)-terminated alkanethiols having structure HS- (CHz)'l(OCH2CHz),nOH (m = 3-7) and their use in the formation of self-assembled monolayers (SAMs) on gold. A combination of experimental evidence derived from X-ray photoelectron sp€ctroscopy (XPS), measurement of contact angles, and ellipsometry implies substantial disorder in the oligo(ethylene glycol)-containing segment. The order in the -(CHz)r- group is not defined by the available evidence. The SAMs are moderately hydrophilic: du(H2O) = 34-38o; d,(H2O) = 22-25". A study of monolayers containing mixtures of HS(CH2)rrCHr and HS(CH2)rr(OCH2CH 2)6OH suggests that the oligo(ethylene glycol) moieties are eflective at preventing underlying methylene groups from influencing wetting by water. A limited study demonstrates that these oligo(ethylene glycol)-containing SAMs resist the adsorption of protein from solution and suggests that SAMs will be a useful model system for studying the adsorption of proteins onto organic surfaces.

TL;DR: Qualitative images showed that p(SBMA) dramatically reduced biofilm formation of S. epidermidis and P. aeruginosa as compared to glass as well as how surface grafting methods will affect the long-term biological performance of the surface coatings.

TL;DR: In this paper, a class of copolymers based on poly(l-lysine)-g-poly(ethylene glycol) (PLL-g-PEG) was found to spontaneously adsorb from aqueous solutions onto several metal oxide surfaces, such as TiO2, Si0.4Ti0.6O2 and Nb2O5, as measured by the in situ optical waveguide lightmode spectroscopy technique and by ex situ X-ray photoelectron spectrograph.
Abstract: The generation of surfaces and interfaces that are able to withstand protein adsorption is a major challenge in the design of blood-contacting materials for both medical implants and bioaffinity sensors. Poly(ethylene glycol)-derived materials are generally considered to be particularly effective candidates for the fabrication of protein-resistant materials. Most metallic biomaterials are covered by a protective, stable oxide film; converting such oxide surfaces, which are known to strongly interact with proteins, into noninteractive surfaces requires a specific design of the surface/interface architecture. A class of copolymers based on poly(l-lysine)-g-poly(ethylene glycol) (PLL-g-PEG) was found to spontaneously adsorb from aqueous solutions onto several metal oxide surfaces, such as TiO2, Si0.4Ti0.6O2, and Nb2O5, as measured by the in situ optical waveguide lightmode spectroscopy technique and by ex situ X-ray photoelectron spectroscopy. The resulting adsorbed layers are highly effective in reducing th...
