“…As a consequence, much more nucleation rate occurs at the expense of the particles growth rate. Thus, small monodispersed nanoparticles are obtained and vice versa [29][30][31]. Addition of stabilizers as natural and synthetic polymers to metal components, using different methods, is used to prevent the coalescence of the nanoparticles [17].…”

Polyvinylpyrrolidone (PVP) is employed in several potential applications, relying of its special chemical and physical properties in addition to its low toxicity and biocompatibility. The aim of this work is to prepare polyvinylpyrrolidone-silver (PVP-Ag) nanocomposite with high inhibiting effect on the microbial growth and low cytotoxicity. In situ prepared small stable spherical silver nanoparticles, with narrow range particle size distribution, were obtained by easy, economical and rapid chemical reduction method. Silver ions were reduced to silver nanoparticles using low amount of sodium borohydride (NaBH4) as a strong reducing agent. PVP-Ag nanocomposite was prepared using PVP as a stabilizing and capping agent. Formation of the spherical silver nanoparticles with mean particle size 5 nm was confirmed by ultraviolet-visible spectroscopy, high resolution transmission electron microscopy, and dynamic light scattering. The inhibiting growth effect of the nanocomposite toward Gram-positive bacteria (Staphylococcus aureus), Gram-negative bacteria (Pseudomonas aeruginosa), and yeast fungus (Candida albicans) were studied. The cytotoxicity of the nanocomposite against BJ1 normal skin fibroblast cell line was tested. Results of this work presented perfect antimicrobial activity of the PVP-Ag nanocomposite towards bacteria and fungi with low cytotoxicity, which may lead to promising applications in skin wound healing.

“…This chapter is devoted to the very contemporary themes of polymer nano-metallization, the process giving the polymers exceptional properties in biological applications, namely the bactericidal action while preserving sufficiently low cytotoxicity level [1][2][3][4][5][6][7][8], as well as to novel techniques for metal nanoparticle (NP) synthesis providing antibacterial, cell-conform entities [9,10]. So far many efforts has been spent to synthesize the next generation antimicrobial materials applicable in the health-care industry in response to increasing resistance of the pathogens to conventional antibiotics [9][10][11][12]. A lot of strategies have been developed to produce those sophisticated manmade materials which hinders their single-key classification.…”

Noble and Precious Metals - Properties, Nanoscale Effects and Applications

Noble metals in their diverse nanoforms bring revolution to many fields of science and technology, as they provide unique properties over their bulk counterparts. Thanks to these completely unprecedented properties, commercial sphere pressure is growing to use them in everyday life. Unfortunately, one of the issues that are subject to dramatic changes is the reactivity of these structures. This may have often fatal consequences to the living organisms. Due to the fact that the mechanism of action of metal nanostructures on living organisms is not yet fully elucidated even in the case of the most studied noble metals such as gold and silver, it is necessary to continue intensively in their research, characterization and categorization. The main prerequisite for the undistorted study of interactions of nanostructures with living organisms is the use of suitable methods of their preparation. Within this context, this chapter attempts to summarize current knowledge form the field of synthesis of metal nanoparticles, layers, wires, and other nanostructures, especially regarding novel techniques of their preparation and extend them by our own results in this area, in the context of their biological properties. More specifically, antibacterial efficacy and potential cytotoxicity of those structures are thoroughly addressed.
