A custom made non‐equilibrium atmospheric pressure argon plasma jet was developed for the deposition of PEG like coatings in open‐air for cell repellent applications. OES and electrical measurements were performed to characterize the discharge. The emission of the N 2 (C 3 Π u –B 3 Π g ) was followed in order to minimize the air entry in the plasma. Surface analyses were carried out on ap‐DEG coatings and the best retention of COC was obtained under mild plasma conditions. The ap‐DEG coatings were compared with typical LP deposited PEG like coatings. Less retention of COC and therefore less cell repellent properties were observed for ap‐DEG coatings as compared to those deposited at low pressure.
