Nanoparticulate surfaces possessing antimicrobial andfungicidal properties under visible light illumination havefound wide applications in a number of fields. In this study,titania nanotubes, as well as titania compact films weredesigned with pure Cu2O crystals in a mildly acidic copperacetate solution using a simple alternating current (AC)deposition approach. In this way, the thermally oxidized Tisubstrate was coated by densely packed pyramidal and bipyramidalshaped Cu2O crystals with dominant (111)planes and investigated against several types of fungi andbacteria. For comparison, TiO2 nanotube (TiNT) films werealso decorated with similar crystals and tested. The resultsshowed that, compared to bare TiO2 films, both Cu2O-in-TiNT and Cu2O-on-TiO2 heterostructures exhibitedremarkably enhanced activity against tested fungi andbacteria. We also demonstrated that the high photoactivityof these crystals remained even after 50 h stability testsunder bright light illumination. The results obtained fromin vitro tests indicated that Cu2O-in/on-TiO2 heterostructuresshow promise as visible light driven antimicrobialmaterials
