The localized depositions such as DNA or proteins at the micron or submicron scale on solids supports are a crucial step in the fabrication of advanced biochips and laboratory on chip devices. The present work shows a new approach: A new biofunctionalized copolymer based on 80% benzyl methacrylate and 20% succinimydil methacrylate is used as a printable polymer with a great affinity to proteins, leading to combined areas covered by proteins and areas with resistance to protein adsorption in the submicron scale. Based on this approximation, an immunoassay is proposed as a proof of concept to detect the presence of the rabbit IgG protein up to concentrations of 200 ng/ml.
