Polyethylene glycol (PEG)-like films were grafted onto various substrates by plasma polymerization of diethylene glycol dimethyl ether (diglyme). Low-power diglyme plasma conditions yielded PEG-like films exhibiting nonfouling behavior, as evidenced by the significant decrease in protein adsorption and cell attachment
