Synthesis and anti-bacterial activity of Cu, Ag and Cu–Ag alloy nanoparticles: A green approach

The influence of metal nanoparticles on the mechanical properties of composite materials

“…Успешные результаты метода полиолов проявляются под действи-ем СВЧ-излучения [25,[30][31][32]. Волновая энергия применяется для нагрева компонентов при растворении агентов и смешении конечного раствора [33].…”

Role of Biopolymers in Green Nanotechnology

“…The concept of green nanoparticles preparation using starch as stabilizer was first reported by Raveendran et al [23] where glucose was used as the reducing agent. The synthesis of stable Cu nanoparticles is of particular interest because of its tendency to get oxidised in an aqueous system [24]. Schematic representation of formation of copper nanoparticles in aqueous matrix of biopolymer such as starch can be seen in Fig.6.…”

“…Bimetallic nanoparticles, either as alloys or as core-shell structures, exhibit unique electronic, optical and catalytic properties compared to pure metallic nanoparticles [24]. Cu-Ag alloy nanoparticles were obtained through the simultaneous reduction of copper and silver ions again in aqueous starch matrix.…”

“…It has been reported that copper nanoparticles show good catalytic activity both as homogeneous and heterogeneous catalytic hydroxylation of phenol by hydrogen peroxide to dihydroxybenzenes [3][4][5] . Copper nanoparticles show also antimicrobial activity, the starch-stabilized copper nanoparticles exhibited interesting antibacterial activity with both gram positive and gram negative bacteria at micro molar concentrations 6 . The copper nanoparticles have lethal effects against Escherichia coli, B. subtilis and S. aureus microorganism 7,8 .…”
