Biological potentials of nephelium lappaceum mediated green synthesised silver nanoparticles

Title : Biological potentials of nephelium lappaceum mediated green synthesised silver nanoparticles

Abstract:

Here in this research paper, silver nanoparticles (AgNPs) are synthesized using the aqueous extract of Nephelium lappaceum L. leaves through an environmentally sustainable, plant-mediated approach. This plant mediated method serves as a simple, sustainable method to conventional chemical methods. The resulting nanoparticles were characterized using UV visible spectroscopy, FTIR, XRD and SEM techniques. Synthesized AgNPs showed effective dye degradation activity, against Reactive Yellow and Reactive orange. Cytotoxicity tests revealed a concentration-dependent effect on seed germination and root elongation, indicating possible biological interactions. Their antioxidant capacity, assessed using H2O2, DPPH and FRAP assays, showed good free radical scavenging activity. Moreover, when applied to Trigonella foenum-graecum, the AgNPs enhanced early plant growth at lower concentrations, suggesting their potential in agricultural improvement.
