ABSTRACT

Carbon nanotubes offer an alternative and promising platform of drug delivery system due to their distinct and unified physicochemical properties. On the account of its great potential, these nanostructures have been employed as efficient delivery system of many therapeutic active compounds, ranging from antineoplastic agents, cardiovascular drugs, anti-infectives to anti-inflammatory molecules, and genes. In concert with their great promise, this chapter is devoted to the literature of chemistry of carbon nanotubes. Herein, we aim to discuss extensively many aspects of these materials including functionalization, drug loading capacity, and mechanisms. Subsequently, the literature on recent patents is surveyed to shed light on the current status of the field. Lastly, their potential applications as different therapeutic modalities in drug delivery, their toxicology profiles, and the developed strategies to overcome their cytotoxicities are also discussed with a detailed perspective.
