“…Nanosilver and its compounds are well established, and have wide antibacterial spectrum (Mahapatra and karak 2008;Tiwari et al 2008). Owing to their strong antimicrobial properties, AgNPs find a plethora of applications such as nanosilver coated ceramic water filters, activated carbon air filters, wound dressings (Maneerung et al 2008;Sharma et al 2009), catheters, biodegradable poly(L-lactide) (PLA) fibers (Xu et al 2006), cosmetics, antibacterial sprays, and children's toys (Jones and Hoek 2010).…”

Eco-friendly green synthesis of silver nanoparticles using salmalia malabarica: synthesis, characterization, antimicrobial, and catalytic activity studies

et al. 2015

An economically viable and ''green'' process has been developed for the synthesis of silver nanoparticles (AgNPs) with an average size of 7 nm using non-toxic and renewable salmalia malabarica gum (SMG) as reducing and capping agent without using any chemical reducing agent. The effect of various parameters such as concentration of SMG and silver nitrate and reaction time for the synthesis of AgNPs was studied. The synthesized AgNPs are systematically characterized by UV/Vis spectroscopy, Fourier transform infrared spectroscopy, X-ray diffraction and Transmission electron microscopy. The resultant SMG-capped AgNPs are highly stable and had significant antibacterial action on both Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus). The catalytic action of the SMG-capped AgNPs to initiate the reduction of 4-nitrophenol (4-NP) in the presence of NaBH 4 has also been reported. The kinetics of the reaction was found to be of pseudo-first-order with respect to the 4-NP.

“…Silver nanoparticles are of particular interesting due to their role as substrates in the studies of catalysis (Tsujino and Matsumura 2005;Shimizu et al 2010), surface enhancement, Raman spectroscopy (Debarre et al 2004;Terekhov et al 2011) and in the biomedical field (Xu et al 2006;Liu et al 2010;Krishna Rao et al 2012). Because of their vast applications in various fields, many techniques of synthesizing silver nanoparticles have been investigated and some of them are: chemical reduction (Bhui and Misra 2012), electrochemical reduction (Starowicz et al 2006;Hosseini and Momeni 2010), photochemical reduction (Kutsenko and Granchak 2009), microemulsion (Zhang et al 2011), gamma-ray irradiation (Huang et al 2009;Rao et al 2010), UV irradiation (Spadaro et al 2010), ultrasonic method (Byeon and Kim 2012), microwave method (Nadagouda et al 2011), etc.…”

A novel green one-step synthesis of silver nanoparticles using chitosan: catalytic activity and antimicrobial studies

et al. 2012

View full text Add to dashboard Cite

Stable silver nanoparticles were synthesized using chitosan acting as both reducing and stabilizing agent without using any toxic chemicals. This reaction was carried out in an autoclave at a pressure of 15 psi and 120°C temperature by varying the time. The influence of different parameters such as time, change of concentration of silver nitrate and concentration of chitosan on the formation of silver nanoparticles were studied. The synthesized silver nanoparticles were characterized by UV-visible spectroscopy, Fourier transform infrared, X-ray diffraction and transmission electron microscopy. The results of catalytic reduction of 4-nitrophenol by sodium borohydride in the presence of green synthesized silver nanoparticles were presented. The antimicrobial activity of silver nanoparticles was tested against Escherichia coli and Micrococcus luteus and was found to be possessing inhibiting property.

“…Several studies aimed at incorporation of Ag-NP within electrospun nanofibers which can enable production of functional nanofibrous composites by combining the unique properties of nanofibers with that of Ag-NP (Mahanta & Valiyaveettil, 2012;Nam et al, 2010;Shi et al, 2011;Xiao et al, 2012). Yet, the size control and uniform distribution of Ag-NP without aggregation in the polymeric nanofiber matrix is challenging, therefore, a number of different approaches were followed for obtaining electrospun polymer/Ag-NP composite nanofibers (Jin et al, 2007;Li et al, 2006;Patel, Li, Wang, Zhang, & Wei 2007;Xiao et al, 2012;Xu et al, 2006). However, in these approaches silver salt precursor was directly added to the polymer solution and the synthesis of Ag-NP was carried out through thermal (Jin et al, 2007;Patel et al, 2007), chemical (Xiao et al, 2012;Xu et al, 2006) and photoreductive posttreatment of the electrospun nanofibers.…”

a b s t r a c tOne-step synthesis of size-tunable silver nanoparticles (Ag-NP) incorporated into electrospun nanofibers was achieved. Initially, in situ reduction of silver salt (AgNO 3 ) to Ag-NP was carried out in aqueous solution of polyvinyl alcohol (PVA). Here, PVA was used as reducing agent and stabilizing polymer as well as electrospinning polymeric matrix for the fabrication of PVA/Ag-NP nanofibers. Afterwards, hydroxypropyl-beta-cyclodextrin (HP␤CD) was used as an additional reducing and stabilizing agent in order to control size and uniform dispersion of Ag-NP. The size of Ag-NP was ∼8 nm and some Ag-NP aggregates were observed for PVA/Ag-NP nanofibers, conversely, the size of Ag-NP decreased from ∼8 nm down to ∼2 nm within the fiber matrix without aggregation were attained for PVA/HP␤CD nanofibers. The PVA/Ag-NP and PVA/HP␤CD/Ag-NP nanofibers exhibited surface enhanced Raman scattering (SERS) effect. Moreover, antibacterial properties of PVA/Ag-NP and PVA/HP␤CD/Ag-NP nanofibrous mats were tested against Gram-negative (Escherichia coli) and Gram-positive (Staphylococcus aureus) bacteria.
