Formation of gold nanoparticles in aqueous solutions of cellulose derivatives and a study of the properties of these nanoparticles

Influence of Carboxymethyl Cellulose on the Green Synthesis of Gold Nanoparticles Using Gliricidia sepium and Petiveria alliacea Extracts: Surface-Enhanced Raman Scattering Effect Evaluation

“…According to the stabilization of MNPs, fluorides, carboxylates, polymers, and acids have been reported; − however, these can modify the chemistry of the surface and the electrical, catalytic, and optical properties. Natural derivatives such as chitosan, hydroxypropylmethylcellulose, and other cellulose derivatives such as ethylcellulose , and carboxymethylcellulose , have also been used. The latter is mentioned as a reducing agent and stabilizer of MNPs , and as a matrix to form metallic films for biomedical applications. , Carboxymethyl cellulose or CMC is a linear-chain macromolecular polymer based on covalent bonds of d -glucopyranoses , due to its hydrosolubility and biocompatibility properties.…”

This research focuses on the use of CMC as a stabilizing and supporting agent for AuNPs and its use for pyridoxine (Pd) (vitamin B6) detection by surface-enhanced Raman scattering (SERS); it also highlights the biocompatibility of the SERS analysis with the green synthesis of MNPs, stimulating the promotion of additional biocompatible mechanisms integrated with this synthesis methodology for the conservation and applicability of colloidal nanoparticles …”
