Microwave Assisted Green Synthesis of Silver Nanoparticles Using Mulberry Leaves Extract and Silver Nitrate Solution

Abstract

In this work, silver nanoparticles (AgNPs) were synthesized quickly and in an eco-friendly manner using the extract of Mulberry leaves and aqueous solution of silver nitrate without any toxic chemicals (Yuet et al. Int. J. Nanomed. 2012, 7, 4263–4267; Krishnakuma and Adavallan. Adv. Nat. Sci. Nanosci. Nanotechnol. 2014, 5, 025018). The Mulberry leaves extract functions as both a stabilizing and reducing agent. The UV-Vis spectroscopy shows a peak maximum at 430 nm. The transmission electron microscopy (TEM) image illustrated of synthesized AgNPs were nearly spherical-shaped particles whose sizes range from 15 to 20 nm. The TEM image of Nano Silver solution sample synthesized by the microwave assisted method shows nearly spherical particles, with an average particle size estimated at 10 nm. The absorption UV-vis spectrum of silver nanoparticles synthesized by the microwave assisted method (AgNPsmw) shows a sharp absorption band around 415 nm. The UV-Vis spectrum of AgNPsmw after two months of storage shows negligible peak changes of silver nanoparticles.

Biosynthesized Silver Nanoparticles Using Morus alba (White Mulberry) Leaf Extract as Potential Antibacterial and Anticancer Agents

“…Four major XRD diffraction peaks at 2θ values were found at 38.38° (111), 44.19° (200), 64.54° (220), and 77.47° (311), which correspond to the crystallographic planes of face-centered cubic ( fcc ) of silver crystal as reported by JCPDS (Joint Committee on Power Diffraction Standards) card No. 00–004-0783 [ 35 , 36 , 37 ]. Similar XRD patterns have been demonstrated by other studies using green synthesis methods to formulate AgNPs [ 35 , 37 , 38 , 39 ], suggesting the nanocrystalline nature of MLE-mediated AgNPs in this study.…”

Effect of feed supplementation with biosynthesized silver nanoparticles using leaf extract of Morus indica L. V1 on Bombyx mori L. (Lepidoptera: Bombycidae)

“…Various mulberry species have been shown to be rich in these bioactive compounds and have high antioxidant capacity 34,43 . Due to these properties, mulberry extracts have been used for synthesis of different nanomaterials such as gold, silver and iron nanoparticles 5,44,45 .…”

Synthesis and Applications of Green Synthesized TiO2 Nanoparticles for Photocatalytic Dye Degradation and Antibacterial Activity

“…M. alba has antioxidant, antibacterial, antiviral, and antiinflammatory properties [14,15]. The mulberry extract using nanoparticles exhibited the enhanced bacterial activity [16][17][18][19][20][21]. The present work reports the green production of TiO 2 (G-TiO 2 ) nanoparticles and their bacterial activity and catalytic dye degradation activity.…”
