How the extremely high length-to-diameter ratio of Carbon Nanotubes makes them special material? Assess their potential applications in public health sector.
Carbon Nanotubes (CNTs) are allotropes of carbon with a cylindrical nanostructure. Carbon nanotubes have varied structures, differing in length, thickness, and number of layers. The characteristics of nanotubes can be different depending on how the graphene sheet has rolled up to form the tube.
This material has exceptional strength and stiffness and due to this, carbon nanotubes with length-to-diameter ratio of up to 132,000,000:1 have been constructed. This is significantly larger than for any other material and makes basis of various applications of Carbon Nanotubes. Some important applications of the carbon nanotube in the field of medicine are as follows:
- Carbon nanotubes for chemotherapy and drug delivery: Carbon nanotubes used in drug delivery can result in drug efficiency and reduced off-target tissue toxicity.
- Carbon nanotubes for gene therapy: Effects of gene therapy are limited by the efficiencies of transfection and system delivery. Since Carbon nanotubes are able to penetrate cells, they are used for gene delivery
- Carbon nanotubes for stem cell related therapies: attempts to design and develop different CNT based tools and devices for tissue engineering and stem cell therapy applications.
- Carbon nanotubes for thermal destruction of tumors
- Arteries Expansion: TO remove blockages in the blood vessels.
With rigorous attempts carbon nanotubes have the ability to address various issues related to human health.
