CNTs Biomedical Applications
Although the exploration of CNTs in biomedical applications is just in progress, it has great potential. Since a great part of the human body is made up of carbon, it is usually considered a very biocompatible material. The growth of cells on CNTs has been demonstrated; therefore, they apparently have no toxic effect. The cells also do not adhere to the CNTs, opening doors for applications such as anti-fouling coatings for ships and coatings for prosthetics.
The ability to functionalize (chemically modify) the sidewalls of CNTs also gives rise to biomedical applications including neuron growth and regeneration, and vascular stents. It has also been demonstrated that a single strand of DNA can be bonded to a nanotube, which can subsequently be effectively inserted into a cell.
