Objective: The present study was carried out for investigating the antibacterial activity of sliver nanoparticles (Ag NPs) biologically synthesized from the medicinal plant Aegle marmelos.
Methods: The silver nanoparticles from Aegle marmelos was impregnated onto a blank disks with different concentrations viz., 1mM, 3 mM and 5 mM and tested for its antimicrobial activity against Escherichia coli (ATCC 25922), Staphylococcus aureus (ATCC 25923), Pseudomonas aeuruginosa (ATCC 27853), and Candida albicans (ATCC 10231).
Results: The results indicated highest antimicrobial activity against E.coli and P. aeruginosa as a solution for finding.
Conclusion: The ability of Aegle marmelos silver nanoparticle to inhibit bacterial and fungi is an indication of its broad spectrum antimicrobial activity which could be a potential source of antibiotic which is cost effective and eco-friendly against drug resistant organisms.

Background/Objectives: Antiaris toxicaria is used as a traditional medicine around many parts of Papua New Guinea. The main aim of this study was to evaluate the compatibility of A. toxicaria by carrying out the phytochemical screening, synthesizing silver nanoparticles using silver nitrate and to determine their antimicrobial activity.
Methods/Statistical analysis: Antimicrobial activity was determined by agar paper disk diffusion essay and the zone of inhibition was measured against 14 microorganisms.
Results: All the test microorganisms were highly susceptible to the green synthesis of silver nanoparticles. Phytochemical screening of A. toxicaria reveals the presence of alkaloids, glycosides, terpenoids, reducing sugars, saponins and phenolic compounds.
Conclusion/Application: The nanoparticles synthesized from the aqueous plant extract of A. toxicaria contains the phytochemicals and it is proved to have the antimicrobial activity.

Background/Objectives: The synthesis of nanoparticles from biological processes is evolving a new era of research interests in nanotechnology. In this study, the possible role of Bridelia minutiflora Hook. F. (B.minutiflora) extract in reducing silver nitrate into silver nanoparticle is highlighted.
Methods/Statistical analysis: The synthesis of silver nanoparticles were prepared by adding silver nitrate solution [3mM] and [5mM] to the plant extract. The silver nanoparticles were characterized using the UV-Visible Spectroscopy. The antimicrobial assay was carried out using the disc diffusion method.
Findings: A comparative study was made in preparing the silver nanoparticles using the boiling method and microwave irradiation method for the B. minutiflora. The results showed promising antibacterial effects against the 15 tested microorganisms. The phytochemical constituent determination shows positive test for terpenoids and reducing sugar.
