Carbon nanotubes (CNTs), a carbon allotrope with various physicochemical
properties, have gained worldwide interest since last two decades. CNTs are made up
of cylindrical shaped graphene foils with nanometric dimension and several
micrometres in length. The application of CNTs in the field of pharmacy and medicine
is based on their large surface area capable to adsorb or conjugate various classes of
drugs, genes, vaccines, and antibodies. This review focuses on the applicability of
CNTs as targeted drug delivery vehicle considering the biopharmaceutics and
toxicokinetics including advantages, obstacles, and perspectives of various CNTs.
