Structural evolution of end-tethered PEO layers chemisorbed on gold studied by specular neutron reflectometry: Effects on protein adsorption
Abstract
The influence of polyethylene oxide (PEO) film architecture on protein resistance was investigated. It was observed that the PEO volume fraction increases significantly and the PEO-solution interface becomes very sharp at a chemisorption time between 0.5 and 4 h. Fibrinogen adsorption experiments indicated that the layer of higher PEO density has lower protein repelling capacity. It was suggested that protein resistance does not increase …
