Study of Stability and Dispersibility of Oxidized Multiwall Carbon Nanotube and Characterization with Analytical Methods for Bioapplication

Abstract

Nanotechnology is the study of manipulating matter on an atomic and molecular scale. Generally, 
nanotechnology deals with developing materials, devices, or other structures possessing at least one dimension size
from 1 to 100 nanometers. Carbon nanotubes have great potentials for novel applications in industry, drug delivery 
system and many other uses. In this work after purification, multiwall carbon nanotube was functionalized in acids 
by liquid phase oxidation method for drug delivery system. The structural and chemical changes after carboxylation 
of MWNTs improved the solubility and dispersibility of the carboxylated MWNTs in water. Fourier transformed 
infrared spectroscopy, and transmission electron microscopies were carried out for characterization of these methods 
of MWCNTs functionalization.
