From: Copper-coated hospital surfaces: reduction of total bacterial loads and resistant Acinetobacter spp.
Copper film surfaces observed by scanning electron microscopy. Copper film without artificial contamination (A) and respective energy-dispersive X-ray spectroscopy (EDS) spectra and elemental mapping of copper (B). Copper film after exposure to Acinetobacter baumannii, with no presence of bacterial cells and flower-like structure in oxidized copper film at different magnifications (C, 200X; D, 1000X; E, 2000X; and F, 4000X)
