【 摘 要 】

The present report summarizes an eco-friendly approach for the biosynthesis of silver nanoparticles (AgNPs) using the leaf extract of lavender. Initially, the synthesis of AgNPs was visually observed by the appearance of a wine red color. The optical property, morphology, and structure of as-synthesized AgNPs were characterized by UV-visible spectroscopy, dynamic light scattering, transmission electron microscopy, and X-ray diffraction analyses. All characterization data revealed the formation of crystalline and spherical AgNPs (Ag/Ag 2 O) with size around 10–80 nm at λ max =440 nm. The surface-modified AgNPs showed an effective catalytic activity toward the reduction of 4-nitrophenol to 4-aminophenol, optical sensing of H 2 O 2 , and antioxidant activity against 1,1-diphenyl-2-picrylhydrazyl. The experimental approach is simple, facile, economical, and easily reproducible without any use of toxic chemicals, and opens up new scope for future biotechnology applications.
