Dispersions of carbon nanotubes and its biomedical and diagnostic applications

Carbon nanotubes (CNTs) have the potential to provide remarkable mechanical and multimodal qualities. However, CNTs are vulnerable to aggregation because of their high surface-to-volume ratio and strong contact force, which limits their applications. The growing interest in using CNTs in a variety of applications has prompted further research into dispersion and functionalization processes. In addition, to use CNTs as a platform for a variety of biological applications, adequate dispersion and interfacial adhesion between the CNTs and foreign molecules must be ensured. The goal of this chapter is to highlight current breakthroughs in the dispersion process of CNTs as well as its intriguing biomedical and diagnostic applications. Current challenges with a focus on toxicity and future prospects of CNTs are also highlighted.
