Green synthesis of silver nanoparticles by a novel method: Comparative study of their properties

► This study presents a novel green method for the synthesis of AgNPs. ► A mixture of Ag+, a starch solution and a supernatant of a fungal culture are used. ► This novel method compared with modified polysaccharide and microbial methods. ► The synthesized AgNPs were characterized by UV-visible, DLS, FTIR, XRD and TEM analyses. ► Results show that the novel method produced high quality AgNPs than the others.
