The target surface treatment of materials for microfluidic chips

The glassworks of the K8 trademark, polymethylmethacrylate and polycarbonate are referred to the most widespread materials used for manufacturing of microfluidic chips. The results of the properties research of wetting action for untreated and treated surfaces of these materials by the sessile drop method are given. The influence of chemical treatment (by alkaline solutions, sodium hypochlorite and methacryloxypropyl-(trimethoxy)-silane) and plasma treatment under argon environment on the surface wetting abilities are discussed. The results of measurement for the relief surfaces of materials by the methods of the atomic force microscopy before and after treatment are considered.
