Sol-gel synthesis of thorn-like ZnO nanoparticles endorsing mechanical stirring effect and their antimicrobial activities: Potential role as nano-antibiotics

“…The studies where ZnO-NPs have demonstrated its anti-pathogenic behavior are plentiful163863737475767778. Its activity has been tested against a plethora of disease causing pathogens, like Salmonella enteritidis , C. albicans , Listeria monocytogenes , and Pseudomonas aeruginosa .…”

Review of Antibacterial Activity of Titanium-Based Implants’ Surfaces Fabricated by Micro-Arc Oxidation

“…Besides, the secondary products such as reactive oxygen species produced by Zn 2+ and Ag + were also harmful to bacteria. Carvalho et al [106] and Jin et al [28] have also proven the enhanced antibacterial activities of simultaneous incorporation of Zn and Ag into Ti. Jin et al [28] believed that the interactions between Zn ions and bacteria were long-range based on the release of Zn ions [27], while the interactions between embedded Ag NPs and bacteria were short-range via the micro-galvanic effects without the release of Ag ions [37,107].…”

Biological behaviour of thin films consisting of Au nanoparticles dispersed in a TiO2 dielectric matrix

“…TiO 2 surfaces have been described as antimicrobial due to its photocatalytic activity after irradiation [13]. However, the antimicrobial activity of TiO 2 thin films without irradiation or without doping the surface with of a known antimicrobial agent such as silver is low against C. albicans [24].…”

“…Au, Ag) and oxides (e.g. TiO 2 ) have been also extensively studied due to their functional properties for antibacterial applications [13] and in the study of biological processes in live cells [14]. Moreover, the knowledge acquired about plasmonic materials allowed building chemical and biological sensors [15], which are based on the detection of changes of their optical response due to presence of molecules and biolayers.…”
