Background:: Synthesis of metallic nanoparticles has attracted extensive vitality in numerous research areas such as drug delivery, biomedicine, catalysis etc. where continuous efforts are being made by scientists and engineers to investigate new dimensions for both technological and industrial advancements. Amongst numerous metallic nanoparticles, silver nanoparticle (AgNPs) is a novel metal species with low toxicity, higher stability and significant chemical, physical and biological properties. Methods:: In this, various methods for the fabrication of AgNPs are summarized. Importantly, we concentrated on the role of reducing agents of different plants parts, various working conditions such as AgNO3 concentration; ratio of AgNO3/extract; incubation time; centrifugal conditions, size and shapes. Results:: This study suggested that eco-friendly and non toxic biomolecules present in the extracts (e.g. leaf, stem and root) of plants are used as reducing and capping agents for silver nanoparticles fabrication. This method of fabrication of silver nanoparticles using plants extracts is comparatively cost-effective and simple. A silver salt is simply reduced by biomolecules present in the extracts of these plants. In this review, we have emphasized the synthesis and antibacterial potential of silver nanoparticles using various plant extracts. Conclusion:: Fabrication of silver nanoparticles using plant extracts have advantage over the other physical methods, as it is safe, eco-friendly and simple to use. Plants have huge potential for the fabrication of silver nanoparticles of wide potential of applications with desired shape and size.

Medicinal Plant Extracts

Silver nanoparticles (AgNPs) are an interesting metal nanoparticle that can be incorporated into pharmaceutical products, including for diabetic foot ulcers as an antimicrobial agent. Green synthesis of AgNPs using plant extracts has been drawing much attention as it is simple, eco-friendly, stable, and cost-effective. This present study was performed to evaluate the potential of three Indonesian medicinal plant extracts, namely Phyllanthus niruri (PN), Orthosiphon stamineus (OS), and Curcuma longa (CL), as reducing and capping agents in the green synthesis of AgNPs, and to optimize their concentrations. Based on the yields and characteristics of the formed nanoparticles, which were analyzed using a UV-Vis spectrophotometer, particle size analyzer, scanning electron microscope, and X-ray diffractometer, Phyllanthus niruri extract at a concentration of 0.5% was concluded as the best extract in the green synthesis of AgNPs. It is thereby a prospective reducing and capping agent for further scale-up studies.

Green biosynthesis of silver nanoparticles utilizing plant extracts is a simple, cost effective system of generating nanoparticles in an ecofriendly environment. In the present study, biosynthesis of silver nanoparticles was carried out using different parts of Madagascar periwinkle plant extracts. The production of the silver nanoparticles (AgNPs) was detected visually by change in color of the reaction mixture from yellow to reddish brown in a 8 h treatment at 37 °C. Further, the AgNPs were analyzed by various standard characterization techniques such UV-Vis spectroscopy, Electron Microscopy (TEM and SEM), FT-IR, and GC-MS analysis. The UV-Visible spectrum showed the plasmon resonance peak for AgNPs at 435 nm, indicating the formation of silver nanoparticles. FTIR analysis showed a good interaction between the plant extract and NPs. The morphology of the NPs varied in shape has observed through TEM with the particle size less than 10 nm. The phytoformulated nanoparticles were found to be well dispersed in solution and stable due to capping molecules present in the reaction mixture. The chromatographic analysis (GC-MS) displayed a prominent fragmentation pattern especially at the higher molecular weight in the range of 280 to 271. Angiogenesis is an important physiological process that plays a crucial role in several pathological conditions (tumor growth and metastasis). The green synthesized AgNPs were assessed for their angiogenic inhibition properties using zebrafish embryos as a model system. The biogenic AgNPs treatment at the dose of 100 μl and 150 μl showed significant anti-angiogenesis (inhibitory effect on angiogenesis), which represents more effectiveness in controlling the vessel formation during pathological conditions.
