Abstract: The aim of this study was to optimize the biosynthesis of silver nanoparticles using leaves of Aegle marmelos as the primary source. The optimal reaction medium comprised 2:1 concentration of leaf extract and 6mM concentration of silver nitrate solution (pH 7. The biosynthesized silver nanoparticles were confirmed by UV-Vis spectroscopy at 420 nm, XRD and FTIR analysis. The antimicrobial properties of silver nanoparticles were confirmed with Bacillus subtilis and Pseudomonas aeruginosa.

“…However, as the reaction time increased, the sharpness of the SPR peak increased too. This is often a factor of the size, shape dispersion; nature of biomolecules and surrounding media characteristics of the phytochemical reducing agent, as different extracts give varying SPR results [ 34 , 35 , 36 ]. The range of the wavelengths throughout the incubation time was within 405–411 nm, with continuous increase in intensity which reflects the presence of a considerable amount of monodispersed and stable AgNPs.…”

“…Huang et al [ 29 ] further confirmed the spectroscopic measurement for nanoparticles at 400–450 nm. Shivakumar and Vidyasagar [ 30 ] and Christopher et al [ 31 ] observed a characteristic peak for silver nanoparticle of at 420 nm for Annona reticulata and Aegle marmelos , respectively. In the present study, a characteristic peak was also observed at 405 nm for the silver nanoparticles of O. chinensis .…”

“…For each of the plant extracts, fifteen conical flasks were labeled 1 -15. Then 90 ml of 1 mM silver nitrate was mixed with 10 ml each plant extract in each test tube, after the pH was adjusted using either 0.1 M HCl or 0.1 M NaOH solution [22] and buffered with 10 ml 0.1M phosphate buffer. Each mixture was left to synthesize AgNPs for a period of time and at temperature as defined in Table 1.…”
