These cylindrical carbon molecules have novel properties that make them potentially useful in many nanotechnology applications. Their unique surface area, sti_ness, strength and resilience have led to much excitement in the _eld of pharmacy. Carbon nanotubes are categorized as single-walled carbon nanotubes (SWNTs) and multi-walled carbon nanotubes (MWNTs). Techniques have been developed to prepare nanotubes in sizeable quantities, such as: arc-discharge, laser-ablation, chemical vapor-deposition, silane-solution and ame-synthesis methods. The properties of CNTs are still being researched heavily and scientists have barely begun to tap the potential of these structures. They can pass through membranes, carrying therapeutic drugs, vaccines and nucleic acids deep into the cell to targets previously unreachable. Overall, recent studies regarding CNTs have shown a very promising glimpse of what lies ahead in the future of nano-medicines. This project presents the unique atomic structure, properties, application and problems of carbon nanotubes (CNTs). The electronic band structure of carbon nanotubes along with their small size and low dimension are responsible for their unique electrical, mechanical and thermal properties. More over the project focuses on the preparation, puri_cation and characterization of CNTs by Transmission Electron Microscope (TEM)enCarbon NanotubesOriginApplicationPreparation and CharacterizationTransmission Electron MicroscopyThesis
