Abstract
In the presented work “smart” antibacterial surfaces based on silver nanoparticles (AgNPs)embedded in temperature-responsive poly(di(ethylene glycol)methyl ether methacrylate)- (POEGMA188)as well as poly(4-vinylpyridine)– (P4VP)coatings attached to a glass surface were successfully prepared. The composition, thickness, morphology and wettability of the resulting coatings were analyzed using ToF-SIMS, XPS, EDX, ellipsometry, AFM, SEM and CA measurements, respectively. Temperature-switched killing of the bacteria was tested against Escherichia coli ATCC 25922 (representative of Gram-negative bacteria)and Staphylococcus aureus ATCC 25923 (representative of Gram-positive bacteria)at 4 and 37 °C. In general at 4 °C no significant difference was observed between the amounts of bacteria accounted on the grafted brush coatings and within the control sample. In contrast, at 37 °C almost no bacteria were visible for temperature-responsive coating with AgNPs, whereas the growth of bacteria remains not disturbed for “pure” coating, indicating strong temperature-dependent antibacterial properties of AgNPs integrated into brushes. © 2019 Elsevier B.V.
