Synthesis of ultra small silver nanoparticles using Sn2+ /Sn4+ redox couple as strong reductant
Original language description
Application potential of colloidal particles and nanoparticles is related to their size, shape and other physical and chemical properties. Those properties can be influenced by various ways of synthesis, while the presence of reducing agent and modifiers (polymers, surfactants) are the most vital ones. One of the strongest reducing agents is tin with the redox couple SnII/SnIV and standard potential -0.384 V. This redox system allows to change redox potential just by addition of hydrogen peroxide to the tin(II) solution, which causes its partial oxidation to tin (IV) and changes the ratio between its oxidized and reduced form. Those changes effect redox potential (which is measured by potentiometer) and influent the tailored silver nanoparticles preparation. Antibacterial activity of prepared nanoparticles, with an average size between 3 to 50 nm, were tested against pathogenic and resistant bacteria, while the smallest nanoparticles have showed high antibacterial activity with minimal inhibition concentration (MIC) in units of mg/L.
