dc.description.abstractBacterial attachment to material surfaces can lead to biofilm formation and corrosion, causing severe economic and health problems. Understanding the first step is crucial to proposing a surface that prevents bacterial adhesion and even obtaining bactericidal effects. In this study, photolithography and wet etching were used to texture stainless steel 316 L surfaces with a hierarchical pattern. The effects of texturing on the surfaces were characterized using atomic force microscopy, X-ray photoelectron spectroscopy, glow discharge optical emission spectroscopy, and contact angle analyses. Antimicrobial properties were assessed using a live/dead test performed on Pseudomonas sp. isolated from a marine environment. Our main results highlight that texturing using hierarchical patterns promotes changes in the chemical surface, wettability behavior, and antimicrobial response, highly depending on the length scale of the patterns.
