ABSTRACT
Plant-based nanomaterial synthesis is becoming increasingly common due to its environmental
friendliness and cost-effectiveness. The biological activities of silver and gold nanoparticles
(AgNPs and AuNPs) synthesized from Bryonopsis laciniosa fruit extract were investigated in this
research. The green synthetic method was used to make AgNPs and AuNPs which were then
analyzed using UV-Visible spectroscopy, FTIR, SEM, and EDAX. Diphenyl-1-picryl hydrazyl
radical scavenging assay was used to determine the antioxidant ability of Bryonopsis laciniosa .
In the UV–Vis spectrum, the synthesized BL AgNPs and AuNPs displayed a characteristic
absorption peak. The biomolecules contained in fruit extract were responsible for reducing and
capping the material of silver and gold nanoparticles, according to FTIR spectra. The particles
were found to be crystalline with a face-centered cubic (FCC) structure, according to an XRD
study. The AgNPs and AuNPs were mostly spherical, with an average size ranging from 103.2-
124.84 nm, according to SEM and EDAX data. Furthermore, the Diphenyl-1-picryl hydrazyl
radical scavenging assay (DPPH) revealed that they could be used as a potential scavenger against free radical-induced damage. The current study looked into whether Bryonopsis laciniosa , an
efficient producer of AgNPs and AuNPs could be used as a safe and cost-effective antioxidant.
These results support further research into Bryonopsis laciniosa AgNP and AuNPs for biological
applications.
