大气压等离子体射流可用于以空间定义的方式修改表面。在空气中操作这些射流是一种有效的表面改性工具，然而产生的表面化学物质受到等离子体气体的限制。在这项研究中，我们证明了在聚苯乙烯（PS）表面，使用常压等离子体射流（APPJ）与庚胺的等离子体聚合可以使哺乳动物细胞附着和生长。重要的是，在氦载气中加入七胺单体，与单独使用氦等离子体相比，改变了空间定义的治疗区域。
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.
