“…The most common method for synthesis of stable AgNps is the chemical reduction of silver ions in different stabilizers such as polymers and surfactants [7][8][9][10][11]. Among them, polyvinylpyrrolidone (PVP) attracts considerable attention because of its excellent chemical and physical properties making it a good material as a coating or as an additive to different materials.…”

Hybrid materials based on polyvinylpyrrolidone (PVP) with silver nanoparticles (AgNps) were synthesized applying two different strategies based on thermal or chemical reduction of silver ions to silver nanoparticles using PVP as a stabilizer. The formation of spherical silver nanoparticles with diameter ranging from 9 to 16 nm was confirmed by TEM analysis. UV-vis and FTIR spectroscopy were also applied to confirm the successful formation of AgNps. The antibacterial activity of the synthesized AgNPs/PVP against etalon strains of three different groups of bacteria-Staphylococcus aureus (S. aureus; grampositive bacteria), Escherichia coli (E. coli; gram-negative bacteria), Pseudomonas aeruginosa (P. aeruginosa; nonferment gram-negative bacteria), as well as against spores of Bacillus subtilis (B. subtilis) was studied. AgNps/PVP were tested for the presence of fungicidal activity against different yeasts and mold such as Candida albicans, Candida krusei, Candida tropicalis, Candida glabrata, and Aspergillus brasiliensis. The hybrid materials showed a strong antimicrobial effect against the tested bacterial and fungal strains and therefore have potential applications in biotechnology and biomedical science.

“…As per demand in bioscience and biotechnology along with other field, silver nanoparticles have been synthesized by various methods such as reduction of silver compounds in solution (Wang et al 2005), thermal decomposition of silver compounds (Navaladian et al 2007), microwaveassisted synthesis (Sreeram et al 2008), and laser-mediated synthesis (Zamiri et al 2011), which are well reported. To synthesize silver nanoparticles by the reduction of AgNO 3 , generally sodium borohydride, citrate, ascorbate, etc.…”

Among the various inorganic nanoparticles, silver nanoparticles have received substantial attention in the field of antimicrobial research. For safe and biocompatible use of silver nanoparticles in antimicrobial research, the different biogenic routes are developed to synthesize silver nanoparticles that do not use toxic chemicals. Among those, to synthesize silver nanoparticles, the use of plant part extract becomes an emerging field because plant part acts as reducing as well as capping agent. For large-scale production of antibacterial silver nanoparticles using plant part, the synthesis route should be very simple, rapid, cost-effective and environment friendly based on easy availability and non-toxic nature of plant, stability and antibacterial potential of biosynthesized nanoparticles. In the present study, we report a very simple, rapid, cost-effective and environment friendly route for green synthesis of silver nanoparticles using guava (Psidium guajava) leaf extract as reducing as well as capping agent. This plant has been opted for the present study for its known medicinal properties, and it is easily available in all seasons and everywhere. The biosynthesized silver nanoparticles are characterized by UV-Vis and TEM analysis. The average particle size is 40 nm in the range of 10-90 nm. The antibacterial activity of these nanoparticles against Pseudomonas aeruginosa MTCC 741 has been measured by disc diffusion method, agar cup assay and serial dilution turbidity measurement assay. The results show that green synthesized silver nanoparticles, using guava (Psidium guajava) leaf extract, have a potential to inhibit the growth of bacteria.

“…In addition, the present work has done at room temperature without any further unnecessary conditions or equipments. In addition, boiling and refluxing were not used as the heat-induced process in the shape evolution of silver NPs (Wang et al 2005;Yu et al 2004;Gervais et al 2001;Balan et al 2007;Iglesias-Silva et al 2007;Min et al 2006;Yin et al 2004). Based on our best results, it also seems that MTMS acts as a binder and/or size controller material.…”

“…At present, there are lots of techniques available for the synthesis of metal NPs. The procedure for processing nanosized silver particles can briefly be classified into several methods such as: (i) chemical reduction of silver ions (Toshima et al 1993;Wang et al 2005), (ii) thermal decomposition in organic solvents (Esumi et al1990;Sun et al 2005), (iii) reversed micelle processes (Huang et al 1996;Egorova et al 2000), (iv) photoreduction (Jin et al 2001), (v) ultrasonic radiation (Xiong et al 2002), (vi) co-cirradiation (Henglein et al 1999;Temgire et al 2004), and (vii) microwave irradiation (Pastoriza-Santos et al 2002). A key issue among these techniques is the particle size-controlling that is very important in applications.…”

A new, direct, simple and high yield solution phase synthesis for preparing narrow-sized silver nanoparticles by chemical reduction in aqueous solution of AgNO 3 in the presence of incorporated Sn particles in methyltrimethoxysilane (MTMS) at room temperature is reported. The resulting MTMS-silver nanoparticles were characterized by means of powder X-ray diffraction and transmission electron microscopy. The produced Ag particles present a tight size distribution with an average diameter of about 15 nm. Dispersed silver nanoparticles in tetrahydrofuran-dimethylformamide (1:1) mixture exhibit some broad surface plasmon resonance bands in UV-visible spectrum.
