3 hours ago The effectiveness of protein adsorption/desorption was investigated in terms of polymer coating composition, pH and ionic strength. Mixed PEO/PDMAEMA polymer coatings were formed on a gold substrate according to the “grafting to” method [ 32 ]. The polymer layer was formed by simultaneously grafting PEO and PDMAEMA to the gold substrate.

7 hours ago Adsorption of the proteins fibrinogen, albumin (HSA) and lysozyme on these functionalised plasma polymer surfaces was studied by XPS and quartz crystal microbalance with dissipation (QCM-D). It was also studied whether pre-adsorption with HSA would lead to a passivated surface against further adsorption of other proteins.

1 hours ago The most widely used surface modification approach to prevent or limit protein adsorption is based on the use of poly (ethylene oxide) (PEO). On the other hand, the amount of protein adsorbed on poly(2-(dimethylamine)ethyl methacrylate) (PDMAEMA) coatings can be regulated by the pH and ionic strength of the medium.

3 hours ago Adsorption of GICs and proteins has been studied with fixed angle optical reflectometry at salt concentrations ranging from 1 to 50 mM NaCl. Adsorption of GICs results in high density PEO side chains on the surface. Higher densities were obtained for GICs consisting of PAH∙HCl160(1.6 ÷ 1.9 chains/nm2) than of P2MVPI43(0.6 ÷ 1.5 chains/nm2).

Frequently Asked Questions

What are the applications of protein adsorption in biotechnology?

Biomedical applications of protein adsorption on poly- mer particles include the following: artificial tissues and organs, drug delivery systems, biosensors, solid-phase im- munoassays, immunomagnetic cell separations, and im- mobilized enzymes (1–5).

Does polyaniline doping affect protein adsorption in polymer films?

Conductive polymer films, which are based on de-doping polyaniline (PAN), ions-doped PAN (PAN + ClO 4−) or sodium dodecyl sulfate (SDS) doped PAN (PAN + SDS) were prepared by electrochemical methods. The effect of the polymer film thickness and doping agents of PAN on protein adsorption were investigated.

What is meant by adsorption theory?

According to basic adsorption theory, adsorption can be regarded as a reaction between adsorbate mole- cules (here, protein) and active sites of adsorbent (here, the surface of polymer particles). m is its maximum value (full coverage of surface, or saturated adsorption), and C is the concentration of protein.

Why is protein adsorption irreversible?

Kinetics, Conformational Change, and Denaturation In the 1980s, researchers found that protein adsorption was irreversible. They first assumed that this irreversibility was caused by multiple attachment to the surface, that is, an n active site binds to one protein (the Langmuir isotherm as- sumes 1:1 binding).
