Studies on Synthesis, Characterization and Application of Silver Nanoparticles Using Mimosa Pudica Leaves

Objective: The present study is to synthesize nanoparticles using the leaf extracts of Mimosa pudica and screen for its α-amylase inhibiting potential as well as antibacterial properties. Methods: Silver nanoparticles were synthesized using extract of Mimosa pudica leaves under various conditions such as sunlight, UV and room temperature. The synthesized nanoparticles were further characterized using UV, FTIR, XRD and SEM analyses. The inhibitory effect of the synthesized nanoparticles on bacterial pathogens and α-amylase activity was also studied. Results: Exposure of reaction mixture to sunlight produced maximum amount of nanoparticles, comparatively. The particles showed a dosedependent increase in percentage inhibitory activity on α-amylase enzyme. Moreover, the nanoparticles showed significant inhibitory effect on Bacillus subtilis and Klebsiella pneumonia. Conclusion: Thus the silver nanoparticles synthesized using M. pudica leaves prove to be a significant source of therapeutic agents, however further mechanistic studies are necessary.
