Based on high resolution XPS and ATR-FTIR spectrum, this coating was a thin poly (ethylene glycol)-like film deposited in a microwave cold-plasma of tetraglyme conditions and built up mainly of —CH_2—CH_2—O— linkages on surfaces, and oxygen and carbon formed covalent bond on the interfacial layer between metal and organic films. Plasma protein was adsorbed onto control and stainless steel surfaces, and the relative adsorbed amount of proteins on the surfaces was evaluated by ESCA. The adsorbed protein on modified-surface decreased rapidly compared with control and exhibited particularly effective in preventing protein adsorption.Read More
