Synthesis of Carbon Nanotubes
The synthesis of CNTs is achieved naturally by using graphites and carbon black in a controlled setting. (Iijima, Nature 354:56, 1991). The synthesized CNTs using this technique are generally uneven in their shape, size, mechanical strength, purity as well as in quality due to the irrepressible natural environment. The CNTs which are prepared by using the technique of synthetically developed methods are of significant importance for the pharmaceutical scientists (Awasthi et al., J Nanosci Nanotechnol 5:1616–1636, 2005).
