This image is a composition of two scanning electron microscopic images of the bacterium Staphylococcus capitis on stainless steel versus antimicrobial copper. The image was colored to visualize the bacterial cells (green) either embedded in a biofilm matrix (blue), or covered with copper particles (red/orange). The ESA-Biofilms investigation studies bacterial biofilm formation and antimicrobial properties of different metal surfaces under spaceflight conditions in altered gravity. Both images were taken as part of the preflight experiments for ESA-Biofilms. Image courtesy of DLR, CC BY-NC-ND 3.0.
