Synthesis, characterization and antimicrobial study of cinnamic acid functionalized Ag nanoparticles

In order to improve the antimicrobial activity of Ag nanomaterial and minimum their toxicity, cinnamic acid has been utilized as both reducing agent protecting ligand synthesis silver (Ag) nanoparticles (NPs). The synthesized (CA) functionalized (CA-AgNPs) have characterized by Ultraviolet-visible spectrophotometry (UV), Fourier transform infrared absorption spectra (FTIR), Atomic force microscope (AFM), Transmission electron (TEM). UV results indicated that a strong band peaked at 452 nm which can be ascribed surface plasmon resonance (SPR) AgNPs. FTIR CA-AgNPs was indeed bound on TEM measurements products are round spherical NPs with average particle size 52.8 nm. Antimicrobial tests revealed significant inhibitory effects E. coli C. albicans. prepared in this study expected developed efficient agents.
