A Review on Biomedical Applications of CNTs

In this review we explore an important nanomaterial, the Carbon NanoTubes (CNTs), which are allotropes of carbon organized as graphite tubes one nanometer in diameter and many millimeters in length. Their compact size and mass, great mechanical potency, and high electrical and thermal conductivity account for their remarkable structural, mechanical, and electronic qualities. The large surface area of CNTs allows them to adsorb or conjugate with a broad range of medicinal and diagnostic substances, which has led to their effective use in pharmacy and medicine (drugs, genes, vaccines, antibodies, biosensors, etc.). They have already been shown to be a reliable method of transporting drugs into cells without being broken down first. In addition to their use in drug and gene treatments, CNTs have been put to wide use in other fields, including tissue regeneration, biosensor detection, enantiomer separation of chiral medicines, drug extraction, and pollution monitoring. Perspectives, benefits, and challenges of this intriguing bio nanotechnology are discussed, and the pharmacokinetics, metabolism, and toxicity of several types of CNTs are analyzed.
