We have studied “PEG‐like” plasma‐deposited coatings of poly(ethylene glycol), some of which prevent protein adsorption and cellular adhesion. This enables inhibition of possible inflammatory reactions or rejection of an implant following its insertion into living tissue. Our approach, based on electrical measurements in atmospheric pressure Ar dielectric barrier discharges, enables precise measurements ofE m , the energy absorbed per monomer molecule. Here, we demonstrate the importance ofE min preparing PEG‐like coatings for biomedical applications, for example by highlighting the great importance of molecular weight of monoglyme (1G) or diglyme (2G) monomers, and by obtaining anti‐fouling layers, “PP‐2G,” only with the diglyme. We demonstrate resistance to protein adsorption and cell adhesion of PP‐2G surfaces prepared with optimizedF d(andE m ) values.
