A photoresponsive nanopatterned hydrogel is demonstrated by combining a pH‐sensitive polyelectrolyte, poly(acrylic acid), with bacteriorhodopsin, a light‐activated proton pump capable of causing local pH changes. Utilizing electron‐beam lithography (EBL) on glass substrates, surface‐attached, nanopatterned hydrogels were fabricated capable of de‐swelling upon green light illumination.
