“…The results also demonstrate that glucose played an important role for Ag NPs formation in the presence of hemicellulose since no color change was observed when only hemicellulose was added. The results are in accordance with the previous observation (Peng et al 2013). Glucose probably acted as a reducing agent, resulting in the reduction of Ag + to Ag 0 .…”

“…Hemicellulose was obtained from bamboo (Phyllostachys pubescens Mazel) via the same separation method described in previous studies (Peng et al 2013). The bamboo hemicellulose was used as a stabilizer and glucose was used as a reducing agent.…”

“…In the last decade, much attention has been directed to the green synthesis of noble metal NPs using polysaccharides, such as starch (Cheviron et al 2014), chitosan (Jannoo et al 2015), and lentinan . During the process of synthesizing Ag NPs by adding polysaccharides, it has been shown that polysaccharides act mainly as stabilizing agents to stabilize the formed Ag NPs (Peng et al 2013). Several kinds of polysaccharides even behave as stabilizing and reducing agent at the same time (Bakar and Bakar 2008;Amin et al 2013).…”

The unique physico-chemical properties of silver nanoparticles (Ag NPs) have opened up the opportunity for their use in many promising physicochemical and biomedical applications. In this study, an economically feasible approach to green synthesis of silver nanoparticles (Ag NPs) is described using hemicellulose from bamboo. Simultaneously, glucose was used as the reducing agent, and distilled water was used as the reaction medium. UV-vis spectroscopy and transmission electron microscopy were used to investigate the surface plasmon behavior, morphology, and particle size of the Ag NPs. Hemicellulose alone could not reduce Ag + to Ag 0 . The formation rate of the nanoparticles was accelerated when high amounts of glucose were added. Small particle sizes were obtained when high concentrations of hemicellulose were used. The stability of the Ag NPs synthesized using different concentrations of hemicellulose from 0.5 mg/mL to 8.0 mg/mL was also evaluated. Higher initial hemicellulose concentrations produced more stable Ag NPs. The average particle sizes of the NPs after storing for 160 days at 4 °C were still smaller than 10 nm when the initial hemicellulose concentrations were 6.0 and 8.0 mg/mL.

“…[12][13][14][15][16] Bioconjugates of AgNPs have also been prepared and their self-assembly investigated. [17][18][19][20] Various methods, among them biogenic methods, 12,[14][15][16][20][21][22][23][24][25][26][27] have been used for the synthesis of AgNPs. Glucose is well known for reducing Ag + to Ag in alkaline solutions, and this method was also used…”

“…12,22,[25][26][27] In order to protect the obtained AgNPs, besides existing oxidation products of glucose in the reaction system, different stabilizing agents were added, such as gelatin, 22,25 hemicelluloses, 26 or starch. 27 This work reports a new procedure to synthesize AgNPs, using glucose as reducing agent but with an original stabilizing system consisting of tetraethyl orthosilicate (TEOS) and We are interested in understanding the molecular mechanism of local anesthetics, particularly in interfacial phenomena, that occur at the biological membrane level.…”
