Here, a green method is described for the biosynthesis of Ag nanoparticles (Ag NPs) using aqueous extracts leaf Salvia leriifolia as reducing and stabilizing agent. Various techniques such scanning electron microscopy (SEM), atomic force (AFM), transmission (TEM) X‐ray diffraction (XRD) were employed characterization structure morphology bio‐synthesized AgNPs. The results reveal that AgNPs synthesized with uniform spherical average diameters 27 nm. efficient heterogeneous catalyst presented superior antibacterial activity. Direct electrochemistry studies confirmed retained their direct electrochemical This mainly attributed to proper process, large specific surface area good conductivity nanoparticles. Hence, present displayed electrocatalytic activity reduction nitrite ions. proposed highly recommended novel platform development sensors which can further expand applications Antibacterial was evaluated against nine microorganisms. prevented growth all selected bacteria. inhibited Pseudomonas aeruginosa, Klebsiella pneumonia, Staphylococcus coagulase, Acinetobacter baumannii, Streptococcus pneumonia more than antibiotic vancomycin, however, ability Echerishia coli Serratia marcescens less antibiotic.
