Up till now altered viruses were used as common carrier vehicles for delivering therapeutic drugs but one of the side effects of this technique was that the virus infected the cells but now with the aid of nanotechnology nonviral nanocarriers it has become possible to deliver gene and drugs. Besides virus even inorganic nanomaterials and polymeric systems are being considered for nonviral delivery vehicles.
Carbon nanohorn or CNH have a dahlia flower like structure and large surface area can be fabricated with large purity and it offer benefits over and above nanorods and nnaoparticles for serving as synthetic intracellular delivery vehicles. CNHs have higher adsorbability for holding therapeutic drugs and they can dissolve quickly in water. Incubation of modified CNHs along with human cervical cancer cells was used for studying the cytotoxicity of CNHs. This has proved that CNHs are toxic and high purity can be achieved without using metallic catalysts. Further studies are being undertaken for making it a success.
