Schematic representation of the immobilization process of IgG on SU-8 substrate and of anti-human IgG binding: (a) oxygen plasma treatment for nanotexturing and surface chemical modification of SU-8, (b) IgG immobilization on surface, (c) blocking with a BSA-based solution, (d) incubation of anti-human IgG to evaluate the bioactivity of the immobilized IgG.
