Synthesis, characterization and antimicrobial activity of dextran stabilized silver nanoparticles in aqueous medium

► The particle size is observed in the range of 10-60 nm. ► Surface morphology of the well-dispersed silver nanoparticles is studied. ► The crystalline nature of Ag nanoparticles is confirmed by X-ray diffraction (XRD) analysis. ► The antimicrobial activities of as synthesized silver nanoparticles is tested against different bacteria.
