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