Tungsten film as a hard and compatible carrier for antibacterial agent of silver

In vitro antibacterial properties of MoO3/SiO2/Ag2O nanocomposite coating prepared by double cathode glow discharge technique

“…The influences of the Ag 2 O addition on the microstructure, chemical bonding states and photocatalytic property of the as-synthesized nanocomposite coating were characterized using X-ray diffractometer (XRD), X-ray photoelectron spectroscopy (XPS), Scanning electron microscope (SEM), Transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FTIR), UV-visible spectroscopy and Raman spectroscopy. Four representative microorganisms relevant to nosocomial infection [19,20], including two Gram-negative bacteria (Escherichia coli and Salmonella Typhimurium), one Gram-positive bacteria (Staphylococcus aureus) and one fungi (Candida albicans), were utilized to evaluate the in-vitro antibacterial and antifungal activities for the MoO 3 -SiO 2 -Ag 2 O nanocomposite coating.…”

Sputter-Deposited Cr–Ag Films for Environmental Antimicrobial Applications

“…The wettability of the samples was assessed by measuring water and glycol contact angles using a contact angle goniometer (JY-82A, Dingsheng Testing Equipment Co. Ltd, Chengde, China, drop volume 5 µL) under ambient conditions. The surface energy of the samples was determined from the above contact angles with the method based on Owens -Wendt theoretical model [15,18]. A water droplet (2 µL) was dropped, or a layer of water film was sprayed on the sample surface, and the water drying process was observed with an optical microscope.…”

“…However, silver segregation often occurs for these composite coatings [11][12][13][14][15] and it increases the biocompatibility concern of silver. Thus, transition metal-silver films are developed for antibacterial applications, including Ti-(Cu)-Ag, Nb-Ag and W-Ag films [10,[16][17][18].…”

A bio-sensing surface with high biocompatibility for enhancing Raman scattering signals as enabled by a Mo–Ag film

“…Due to its high hardness, the Mo film possesses excellent wear resistance, especially for the manufacturing of reusable devices. 24 Based on our reports on the Ta–Ag film, 10 W–Ag film, 21 and Cr–Ag film, 22 the development of Mo–Ag surfaces should be expected, and the biological performance for SERS sensing should be determined, such as the hydrophilicity, cytocompatibility and signal sensitivity.…”
