Effect of sonication and aging on the templating attribute of starch for “green” silver nanoparticles and their interactions at bio-interface

Antifungal activity of transparent nanocomposite thin films of pullulan and silver against Aspergillus niger

“…More recently, the use of biopolymer matrices for the preparation of silver composites has gained great relevance due to their renewable nature, biocompatibility and biodegradability [11,12]. Examples of silver nanocomposites that have been described as antimicrobial agents comprise those of chitosan [13], cellulose [14], starch [15], dextran [16] and alginate [17]. However, to the best of our knowledge, studies on the antifungal properties of nanocomposites that combine Ag NP and pullulan have not been reported.…”

A caffeic acid mediated facile synthesis of silver nanoparticles with powerful anti-cancer activity

“…The resonance position and peak width depend on many factors and several physical properties of AgNPs [34]. The UV-vis spectra also demonstrated that the obtained AgNPs were highly mono-dispersed because the absorbance peaks were sharp as reported by literature in which a narrower SPR peak indicated a smaller size distribution [29].…”

“…The silver ions subsequently oxidized the hydroxyl groups into carbonyl groups in the reduction reaction as the silver ions were simultaneously reduced into the AgNPs. Several studies have recently reported that an alkaline medium is a pre-requisite for synthesis of AgNPs using active reducing components from the bio-resources [28][29][30][31].…”

Green Chemistry Based Benign Routes for Nanoparticle Synthesis

“…Here, the investigators have revealed that, by the use of ultrasonication, time consumption is less, product yield is better, and the shape of synthesized silver nanoparticles is better controlled and built [79]. The charm of these ever reliable, simple, and adorable nonconventional routes of nanoparticle synthesis routes is ever increasing as highlighted by some related studies, of similar background [80][81][82]. This mounting development of alternative synthesis routes for nanoparticle synthesis clearly exemplifies that better control is achieved through these methods and energy requirements as well as technical sophistication is far less.…”
