Objective: The present study was designed to biosynthesize NPs from leaves to study the reducing Ag+ions and stabilizing the particles and confirm AgNP synthesis by using various spectroscopy and microscopic methods.Methods: Bio-inspired AgNPs were rapidly synthesized at room temperature using fresh aqueous leaf extract of Carica papaya. A green and low-cost synthesis was effective in the formation of stable crystalline NPs in the solution. Amine, alkene and alkyl halides groups present in the Carica papaya leaf extract functioned as reducing as well as a stabilizing agent to produce shape controlled AgNPs.Results: SPR confirmed the formation of AgNPs in UV-Visible spectra at 445.7 nm. The XRD result also showed the presence of elemental Ag+as a crystalline nature. Study the functional groups responsible for the bio reduction of Ag+. HE-TEM and FE-SEM with EDX image showed spherical crystalline AgNPs.Conclusion: Hence, the plant-based bio AgNPs could be used in biomedical applications.
