In the nanotechnological development, carbon nanotubes (CNTs) have attracted a great deal of attention due to their unique structural, electrical and mechanical properties. Some of the properties of CNTs for example, superior strength; flexibility, electrical conductivity and easy chemical functionalization have been exploited for the biological application both at the cellular and molecular level. Chemical modification of CNT tips has allowed for applications such as conducting measurements as a function of pH, imaging based on specific molecular interactions, and measuring single molecule protein-protein interactions, This review highlights the various preparation methods, types, and other information regarding carbon nanotubes to a pharmaceutical scientist, hence a systemic exploration may provide a lead in establishing possible application of CNTs in this challenging and of nanotechnology based drug delivery.
