Carbon Nanotubes: A New Line to Drug Delivery

Neelesh Mehra, Sarvesh Sharma, A. K. Singhai, Vimal Kumar

Abstract: Carbon nanotubes are molecular-scale tubes of graphitic carbon with outstanding properties. They are among the stiffest and have remarkable electronic properties and many other unique characteristics. The field of carbon Nanotubes technology has been revolutionary as substantial technical and scientific growth in basic sciences. 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.
Introduction
Nanotechnology is likely to revolutionize our lives, in general, and health scenario, in particular. It is an emerging discipline that encompasses an increasingly sophisticated ability to manipulate matter at the nanoscale (0.1 nm to 1000 nm), resulting in new materials, products, and devices that demonstrate new and unusual behavior. It is one of the most important research and development areas in modern science. Apart from this, nanomaterials, nanoparticles, and nanocomposites used for biomedical purposes constitute a burgeoning new field called nanomedicine, which implies the medical application of nanotechnology and related research leading to the designing, testing, and optimizing of the pharmaceutical formulations. Nanotechnology is an applicable aspect of a broader area of nano science (nano means 10-9 m), which is one of the upcoming and highly challenging as well as a rewarding key research area in the modern scientific set-up. It is the science of small particles having unique properties, which change on altering the size of the particles. As nanotechnology is a very broad term, there are many disparate but sometimes overlapping subfields that could fall under its umbrella. It is a highly multidisciplinary field, drawing from fields such as applied physics, materials science, colloidal science, device physics, supramolecular chemistry, and even mechanical and electrical engineering. Nanotechnology, a contemporary discipline, has emerged in the field of cell biology in the form of nanosized particles such as liposomes to dendrimers and quantum dots to carbon-based nanoparticles including, fullerenes and carbon nanotubes (CNTs), also known as bucky tubes.
