Abstract

Abstract : Atmospheric‐pressure plasma jets can be used to modify surfaces in a spatially‐defined manner. Operating these jets in air is an efficient surface modification tool, however the resulting surface chemistries are limited by the plasma gases. In this study we demonstrate that plasma polymerization with heptylamine on polystyrene (PS) surfaces, using an atmospheric pressure plasma jet (APPJ), can enable mammalian cell attachment and growth. Importantly, the addition of the heptylamine monomer, in a helium carrier‐gas, altered the spatially‐defined treatment area in comparison to treatment with a helium plasma alone. Abstract : To quickly and cheaply create spatially‐defined chemical patterns on surfaces will be beneficial tool in many fields, including biomaterials, and may be achieved with plasma polymerization using atmospheric‐pressure plasma jets. The addition of heptylamine monomer in a helium plasma jet alters the surface chemistry, treatment pattern, and cellular response compared to a helium plasma alone.
