Floral Synthesis of Silver Nanoparticles Using Stenolobium stans L.

Abstract

Green synthesis of nanoparticles has preference due to their non-pollutant nature when compared with other methods of synthesis. In the present investigation, silver nanoparticles were synthesized using green technology as a single step which is cost effective and eco-friendly method. The aqueous floral extract of Stenolobium stans belonging to family Bignoniaceae was used in this study. The synthesized silver nanoparticles were characterized for their plasmon resonance using UV-visible spectrophotometer and scanning electron microscope, Energy dispersive X-ray spectroscopy, Laser particle size analyzer and Fourier transform infrared spectroscopy to study other characters. The UV-visible spectrum showed the absorbance peak at 455 nm. The average size range of nanoparticles was recorded as 7.8 to 45.3 nm through SEM and the presence of silver was recorded through EDS. The zeta particle analyzer revealed the average size range of 28.51 nm. Further the presence of phenolics and other organic group was confirmed through FTIR, which reveals that the floral extract of Stenolobium stans is involved in synthesis of silver nanoparticles. Thus, the floral extract of Stenolobium stans can be used as a potential source for the synthesis of same.
