“…Absorption intensities also increased between 900 and 1400 cm −1 , where the bands of O-H deformation vibrations and C-O stretching vibrations are located. Note that these results are similar to results obtained by us for polypropylene film treatment in APGD under the same conditions [19,20]. The most essential changes were observed in the bands at 1554, 1645, 1740, and 3248 cm −1 .…”

“…We previously showed that such treatment resulted in the formation of different types of oxygencontaining functional groups on polypropylene surfaces as well as the increase of surface energy. The modification process was also able to accomplish the immobilization of some porphyrins onto polymer surfaces [19,20]. As ongoing research, the change of chemical composition and free energy of polyethylene (PE) surface after the APGD action has been investigated.…”

“…8,30 Moreover, they are relatively chemically inert and so frequently require aggressive treatment to alter their physical properties before they can be modified at their surface. [41][42][43] Therefore, surface modification of polymeric materials, and particularly of polystyrene and polyolefine surfaces, is of major interest. 16,44,45 To this end, the surfaces of polystyrene and polyolefine slides were dip-coated with PDA and water-soluble AMP 6 was covalently bound to the resulting surfaces.…”

Non-leaching antimicrobial surfaces through polydopamine bio-inspired coating of quaternary ammonium salts or an ultrashort antimicrobial lipopeptide

Bacterial fouling on surfaces significantly increases the resistance of bacteria toward antibiotics, which leads to medical complications and a corresponding financial burden. Here, we report on a general and robust technique for facile modification of various surfaces with different antibacterial agents. Our approach in this study was inspired by the strong adhesion of mussel adhesion proteins (MAPs) to many types of surfaces, including metals, polymers, and inorganic materials. Thus, glass and polymeric slides were dip-coated with dopamine, as a MAP mimic, and the resulting surfaces were characterized. The reactivity of dopamine-coated surfaces toward nucleophilic addition was then confirmed by reacting them with fluorescent probes containing either a free amino or a free thiol group. Laser scanning confocal microscopy (LSCM), X-ray photoelectron spectroscopy (XPS), confocal Raman microscopy, matrix-assisted laser desorption/ionization-time of flight (MALDI-TOF) mass spectroscopy, and cyclic voltammetry studies collectively suggested that the probes had covalently attached to the surfaces. Fabrication of dopamine-coated surfaces with an antibacterial quaternary amine or an ultrashort lipopeptide analog generated surfaces that effectively kill Escherichia coli and Staphylococcus aureus cells on contact. Moreover, minimal leaching of the fabricated agent was detected after prolonged incubation. This technique could be further developed to a ''paint-like'' or selfassembling monolayer-like procedure for the preparation of antibacterial surfaces on various materials.

We developed a new scheme to generate atmospheric dc glow discharges with a combination of an electrolyte cathode and a miniature gas flow. Stable glow discharges were obtained for a gap separation of 100 -700 mm with a cathode of a sodium sulfate solution. The gap voltage increased with increasing a current up to 15 mA, above which the voltage became constant as the low-pressure glow discharges. Local boiling by the discharge at the surface of the sodium sulfate solution began at 15 mA. At the same time, the emission of an intense sodium atomic line appeared in the negative glow region. The pH of the solution decreased when the discharge was generated in ambient air. The reduction of pH was attributed to the existence of nitrogen oxide, which dissolved in the solution.
