Alginate hydrogel microbeads incorporated with Ag nanoparticles obtained by electrochemical method

► Alginate microbeads incorporated with AgNPs obtained by electrostatic extrusion. ► Electrochemical synthesis of Ag nanoparticles (AgNPs) in alginate solutions. ► Concentration and size of Ag nanoparticles is controlled by synthesis parameters. ► The applied current density does not affect the size of Ag nanoparticles.
