Abstract In this study, biosynthesis of stable silver nanoparticles (Ag NPs) were prepared using Mukia madarasapattana leaf extract. X-ray diffraction analysis revealed the synthesized silver nanoparticles had face centered cubic crystalline structure. The TEM image showed the silver nanoparticles are not agglomerated, moderately mono dispersed with the size of 15 nm. The high negative zeta potential values indicated the dispersion stability of Ag NPs. Antibacterial activity was carried out against different test microorganisms in silver nanoparticles. The cyclic Voltammetry study showed that Ag NPs have an oxidation peak at 0.61 mV. Keywords Ag NPs Mukia madarasapattana Cyclic voltammetry Disc diffusion Antibacterial activity Abbreviations AgNPs Silver nanoparticles SPR Surface plasma resonance
Introduction In this era, nanotechnology is one of the most attractive areas, which is used to explicate the formation and exploitation of materials with structural features between those of atoms and bulk materials with at least one dimension in the nano scale (Song and Kim 2009; Nalwa 2000). Various chemical and physical methods have been Electronic supplementary material The online version of this article (https://doi.org/10.1007/s13562-020-00619-z) contains supplementary material, which is available to authorized users. & K.

used successfully to prepare metal nanoparticles. These techniques remain expensive and involve the use of hazardous materials. Silver nanoparticles (Ag NPs) are being the most investigated of its wide application in the various fields for instance food, cosmetic medicine and environmental (Naik et al. 2002; Okitsu et al.2001). The use of plant extract for the synthesis of nanoparticles may helpful over other biological processes, because it drops the elaborate processes of maintaining cell cultures and also suitable scaled up for large-scale preparation of nanoparticles. Also, the green chemistry approach for the synthesis of silver nanoparticles using plants could avoid the generation of toxic byproducts. Among the various known synthesis methods, plant mediated nanoparticles synthesis is preferred because it is cost-effective, eco-friendly and safe for human therapeutic use (Kumar and Yadav 2009). In the present work, an attempt has been made to prepare Ag NPs through the M. maderaspatana extract and study its antimicrobial ability and electrochemical activity. The experimental proce
