Micro-plasma assisted synthesis of multifunctional D-fructose coated silver nanoparticles

Abstract

Silver nanoparticles have attracted great attention recently owing to their excellent sensing, catalytic and biological applications. Their synthesis is usually carried out by wet-chemical methods, which yields surface coated nanoparticles, often with toxic molecules, which could markedly limit their applications. Herein, we report facile synthesis of silver nanoparticle, with the help of plasma liquid interactions (PLIs) technique, stabilized with D-fructose (DF), which is a common and non-toxic ketonic monosaccharides. Due to the D-fructose coating silver nanoparticles have high self-life and are excellent for biomedical applications. Moreover, we demonstrate that D-fructose coated sliver nanoparticles (DF-AgNPs) are excellent for surface enhanced Raman scattering (SERS) based trace detection and heterogeneous catalysis for degradation of toxic dyes. In particular, they showed excellent SERS enhancement of rhodamine 6 G (R6G) and catalytic degradation of methylene blue (MB). Ultraviolet-Visible (UV–vis) absorption Spectroscopy, x-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), Energy Dispersive x-ray Spectroscopy (EDS) and Fourier-Transform Infrared Spectroscopy (FTIR) were used to characterize the as prepared DF-AgNPs.
