Evaluation of Multiwalled Carbon Nanotube-Silver Nanocomposite: A Fluorescence Spectroscopic Approach.

Abstract

Silver nanoparticles (AgNPs) have been extensively utilized in various fields due to their excellent physical and chemical properties. The green synthetic routes for the synthesis of AgNPs have been adopted to eliminate the impact of the chemicals over the environment. These methods are more cost-effective, eco-friendly and simple. The association of AgNPs on to the surface of functionalized multi-walled carbon nanotubes (f-MWCNTs) produces nanocomposites with unique properties. This can be achieved by different methods such as covalent functionalization, non-covalent functionalization and so on.In the current study, AgNPs are synthesized by biochemical method and they are anchored on to the surface of functionalized MWCNTs is carried out via a non-covalent interaction. The fluorescence studies are done on the nanocomposites in the presence of a suitable external probe i.e., MB. Here fluorescence and UV-Visible spectroscopy are used.
