Inorganic-bio nanocomposites combining photoproteins (aequorin, AEQ) with a Pt-doped α-Fe2O3 (Pt-α-Fe2O3) thin film could induce a photoelectrochemical reaction without an external light source. Blue emission originated from Ca2+ binding to AEQ excited the n-type semiconducting Pt-α-Fe2O3 under an anodic bias, then an anodic photocurrent was clearly observed in a basic solution.
