The unique properties of carbon nanotubes (CNTs) make them a highly interesting and demandable nanocarrier
in the field of nanoscience. CNTs facilitate efficient delivery of therapeutics like drugs, proteins, genes, nucleic acids,
vitamins and lot more. Even though highly beneficial, the biocompatibility of CNTs is a major issue in their questioning
their potential application in targeting drug delivery. Studies confirmed subdued toxicity of CNTs following slight
modifications like functionalization, controlled dimensions, purification etc. A well-established mechanism for cellular
internalization is an insistent need to attain a more efficient and targeted delivery. Recent patents have been thoroughly
discussed in the text below.
