Abstract

 Carbon nanotubes, which are elongated fullerenes, resemble graphite sheets wrapped into cylinders with a high length-to-width ratio (few nm in diameter and up to 1 mm in length). Carbon nanotubes are molecular-scale tubes of graphitic carbon with outstanding properties. Carbon nanotubes have drawn great interest and attraction in the field of novel drug delivery system. Nanomedicines can target, diagnose, monitor and treat cancerous cell also. The small nanoscale dimension and astonishing properties make them a distinctive carrier with a wide range of promising applications. These cylindrical carbon molecules have novel properties that make them potentially useful in many applications in nanotechnology. The various nano-size carrier systems are available for biotechnological applications including the drug delivery. Carbon nanotubes are typically used for bioactive delivery due to their some unique outstanding properties. Carbon nanotubes drug delivery system opens up new potential and possibilities over nanoparticles, dendrimers, liposomes etc. for biomedical applications and new drug delivery. In last few years, Carbon nanotubes (CNTs) have shown unexpected advantages in the field of cancer treatment and drug delivery systems. Present review article discuss in brief about the methods of synthesis, with purification as well as sorting techniques for giving different grades to different types of CNTs and biomedical applications. These show very good adsorption properties which helps in the detection of various chemicals, toxic agents etc. Research done using CNTs for cancer treatment is also discussed in brief.
