Abstract
By combining polymer pen lithography (PPL) patterning with in situ polymerization, we report a straightforward and bottom-up approach for bench-top fabrication of microelectrode arrays (MEAs) with well-controlled dimensions. The as-fabricated MEAs can be used to electrodeposit prussian blue in situ and work as a biosensor for H<sub>2</sub>O<sub>2</sub> with a detection limit as low as 5 nM at a sensitivity of 0.7 A cm<sup>-2</sup> M<sup>-1</sup>.
