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.

Objective: To produce natural, non-toxic biologically synthesized silver nanoparticles (Ag NPs) with antimicrobial activity from plant source, Swietenia mahagoni as a remedy for multi-resistant drug microbes.
Methods: The antimicrobial activity of these Ag NPs from Swietenia mahagoni was tested against three bacterial species, E.coli, S. aureus, P. aeruginosa and a fungal species, C. albicans.
Results: The experimental results exhibited satisfactory inhibitions against all tested microorganisms when used at different concentrations viz., 1mM, 3 mM and 5 mM; 3 mM (20 mg/500 μl distilled water) offered the highest sensitivity for E.coli and P. aeruginosa.
Conclusion: Green-synthesized antibacterial agent from Swietenia mahagoni showed good antibacterial and antifungal activity.

Background/Objectives: In current trend biological synthesis of metallic nanoparticles is gaining importance because it is reliable and eco-friendly.
Methods/Statistical analysis: The present work leads to the synthesis of nanoparticles from 3mM and 5mM AgNO3 solution through aqueous leaf extract of Dysoxylum parasiticum as reducing as well as capping agent by employing boiling method and microwave irradiation method. Synthesized nanoparticles are characterized under UV-Vis spectroscopy at the range of 200-800nm.
Findings: Green synthesized silver nanoparticle showed zone of inhibition against tested microorganisms. The leaf extract shows higher antimicrobial activity found by disc diffusion method. Furthermore, determination of elemental silver was done by the Atomic Absorption Spectroscopy (AAS). The phytochemical constituent determination shows the positive results expect for the test for terpenoids and test for the reducing sugar.
Improvements/Application: Both Boiling Method and Microwave Irradiation Method are effective in synthesizing of silver nanoparticles using the leaves extracts of plants.

Background/Objectives: Green nanotechnology is generating attention of researchers toward ecofriendly biosynthesis of nanoparticles. In this study, the possible role of Sphaerostephanos asplenioides J. Sm extract in reducing silver nitrate into silver nanoparticle is highlighted.
Methods/Statistical analysis: A comparative study was made in preparing the silver nanoparticles using the boiling method and microwave irradiation method for the S. asplenioides. 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.
Findings: The antimicrobial assay was carried out using the disc diffusion method which showed promising antibacterial effects against the 15 tested microorganisms. The phytochemical constituent determination shows the positive results expect for the test for terpenoids and test for the reducing sugar.
Improvements/Application: It can be concluded that both methods (Boiling Method and Microwave Irradiation Method) are effective in synthesizing of silver nanoparticles using the leaves extracts of plants.

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.
