Environmental-amiable pulsed laser ablation in liquid mediated growth of silver/cinammon nanocomposites:absorption attributes

Abstract

by the great prospects of both silver (Ag) and cinnamon (C) nanostructures in the biomedicine applications we prepared some colloidal nanocomposites of Ag-C in the form of nanoparticles (hereafter designated as Ag-CNPs). Very strong reactivity and wide surface area of Ag-CNPs blend made them effective for various biomedical purposes. These Ag-CNPs were grown via green (chemical-free environment) pulsed laser ablation in liquid (PLAL) technique using ethanol as liquid medium at optimum laser fluence. Fourier transform infrared (FTIR) spectra identified the right chemical bonding vibration and confirmed the production of Ag-CNPs dispersed in ethanol. It comprised of several prominent bands assigned to the symmetric and asymmetric stretching of O-H, C꞊O, C-O, C-OH, and C-H bonds. The occurrence of vibrational modes corresponding to hydroxyl and carboxylic functional groups confirmed the existence of polyphenols compounds and their derivatives including cinnamaldehyde, flavanols and phenylpropenes. Ultraviolet-Visible (UV-Vis) absorption spectra revealed two intense absorption bands at 321 nm and 406 nm, confirming the formation of stable Ag-CNPs. These achieved Ag-CNPs with proven unique structural and absorption attributes were established to be beneficial for widespread usage.
