Reusability of parylene membranes as a stencil for multiple protein patterning experiments. FITC-BSA was patterned on PDMS (A) and polystyrene (B) using a single parylene membrane for 10 different patterning experiments. The structural integrity of the membrane was easily preserved through the 10 experiments, as evidenced by the nearly identical protein patterns it produced.
