摘要
The present study reports the synthesis of silver nanoparticles(AgNPs)from silver precursor using banana stem extract(BSE)as a plant biomaterial.Biologically synthesized AgNPs were observed at 425 nm with particle size ranges from 75.50 nm to 1.22µm of truncated octahedron,rhomb-dodecahedron,cubic,octahedron and octagon structures.The presence of water-soluble organic compounds such as flavanones,polyphenols etc.in+the BSE was identified by FTIR which were found to be responsible for the reduction of Ag ions to AgNPs.The EDX analysis of the nanoparticles dispersion,using a range of 2–4 keV,confirmed the presence of elemental silver,with no other impurity peaks detected.In addition,the characterised AgNPs have the potential for various medical and industrial applications.The results showed that fungal susceptibility to AgNPs is different for each fungus.
