Laser‐Textured Surfaces: A Way to Control Biofilm Formation?

Karin Schwibbert, Anja M. Richter, Jörg Krüger, Jörn Bonse

Abstract Bacterial biofilms pose serious problems in medical and industrial settings. One of the major societal challenges lies in the increasing resistance of bacteria against biocides used in antimicrobial treatments, e.g., via overabundant use in medicine, industry, and agriculture or cleaning and …

Spatial Period of Laser-Induced Surface Nanoripples on PET Determines Escherichia coli Repellence

Anja M. Richter, Gerda Buchberger, David Stifter, Jiri Duchoslav et autres

Bacterial adhesion and biofilm formation on surfaces are associated with persistent microbial contamination, biofouling, and the emergence of resistance, thus, calling for new strategies to impede bacterial surface colonization. Using ns-UV laser treatment (wavelength 248 nm and a pulse duration of 20 …
