Carbon nanotubes (CNTs) are allotropes of carbon with a nanostructure that canrnhave a length-to-diameter ratio greater than 1,000,000. These cylindrical carbon moleculesrnhave novel properties that make them potentially useful in many nanotechnology applications.rnTheir unique surface area, sti_ness, strength and resilience have led to muchrnexcitement in the _eld of pharmacy. Carbon nanotubes are categorized as single-walledrncarbon nanotubes (SWNTs) and multi-walled carbon nanotubes (MWNTs). Techniquesrnhave been developed to prepare nanotubes in sizeable quantities, such as: arc-discharge,rnlaser-ablation, chemical vapor-deposition, silane-solution and ame-synthesis methods.rnThe properties of CNTs are still being researched heavily and scientists have barely begunrnto tap the potential of these structures. They can pass through membranes, carryingrntherapeutic drugs, vaccines and nucleic acids deep into the cell to targets previously unreachable.rnOverall, recent studies regarding CNTs have shown a very promising glimpse ofrnwhat lies ahead in the future of nano-medicines. This project presents the unique atomicrnstructure, properties, application and problems of carbon nanotubes (CNTs). The electronicrnband structure of carbon nanotubes along with their small size and low dimensionrnare responsible for their unique electrical, mechanical and thermal properties. More overrnthe project focuses on the preparation, puri_cation and characterization of CNTs byrnTransmission Electron Microscope (TEM)
