Photoreactable bioconjugated macromolecules were synthesized via atom transfer radical polymerization (ATRP), using an N-hydroxysuccinimide ester functional end group with the anti-biofouling 2-methacryloyloxyethyl phosphorylcholine (MPC) units and photoreactable 2-(4-azidobenzamido)ethyl methacrylate units. The polymer was then conjugated with bovine serum albumin (BSA), and the simultaneous patterning of BSA and L-929 fibroblast cells was prepared by a simple coating and irradiation (254 nm UV) process.
