Abstract:

In this article, we report an ecofriendly technique for the preparation of silver nanoparticles (AgNPs) using seed extract of Foeniculum vulgare, and the evaluation of their antibacterial activity. UV-visible spectroscopy, SEM and FTIR analysis were used to characterize the morphology and crystalline phase of AgNPs. Reduction of silver ions using seed extract of Foeniculum vulgare resulted in the synthesis of nanoparticles. The seed extract showed an absorption peak at 475 nm in UV-VIS spectrum corresponding to the plasmon resonance of silver nanoparticles. FTIR spectrum showed the involvement of amides and amines in capping and reduction of silver nanoparticles. Antibacterial activity was screened using synthesized silver nanoparticles against Staphylococcus aureus, Escherichia coli and Pseudomonas aeruginosa. The AgNPs showed potent antibacterial activity against diļ¬€erent types of bacteria. The results confirmed that Foeniculum vulgare is a potential bio-resource/biomaterial for synthesizing AgNPs with applications in antibacterial agents.
