This image is a scanning electron microscopic image of one of the ESA-Biofilms sample plates from the first launch to the ISS. The sample plate in this image is made of copper, which naturally has antimicrobial properties. This surface has a 3 µm laser structure engraved to the surface which improves antimicrobial efficacy. On the surface, only few cells of the bacterial species Staphylococcus capitis are attached. The cells appear small and are not actively dividing. The ESA-Biofilms investigation studies bacterial biofilm formation and antimicrobial properties of different metal surfaces under spaceflight conditions in altered gravity.
