Electrochemical activation for sensing of three‐dimensional‐printed poly(lactic acid) using low‐pressure plasma

Abstract Integrated electrochemical sensors in which plasma‐treated poly(lactic acid) (PLA) single material acts as both selective coating layer and transductor (electrode) are prepared. Thus, three‐dimensional‐printed PLA specimens transformed into electroresponsive by applying a low‐pressure gas plasma treatment with three different gases: N 2 , O air (79% + 21% ). Although all treated samples able to electrochemically detect dopamine, the one derived from of exhibits best performance sensor. Finally, cell adhesion assays demonstrate that viability is higher for modified than pristine PLA, making former promising, versatile, powerful platform diverse applications biomedicine.
