A Review on Carbon Nanotubes and its Biomedical Applications

Abstract

Abstract: Carbon nanotubes, as their name implies, are nanotubes made of carbon. Carbon nanotubes, liposomes, dendrimers, quantum dots, nanogels, and others are carbon nanoparticles. CNTs are synthesized using a variety of processes, including laser ablation, chemical vapor deposition, and arc discharge. Each method affects the nanotubes' final structure, diameter, and chirality, which affects their qualities and future applications. Furthermore, CNT functionalization and doping allow for changes in surface characteristics, compatibility with various materials, and improving performance in multiple applications. Carbon nanotubes are used in drug delivery systems to transport drugs from one place to another to achieve therapeutic effects. Carbon nanotubes have a wide variety of applications like those used in gene therapy, the treatment of cancer, diagnosis, tissue regeneration or engineering, etc. Moreover, CNTs (carbon nanotubes) have been recently revealed as promising antioxidants. They have great results in medicine and pharmacy. Its simple structure, high thermal and electronic conductivity, and nanometer size attract. Carbon nanotubes can deliver proteins, bioactive peptides, drugs, and nucleic acids to organs and cells. CNTs have a thin graphene sheet, which classifies them and changes their functions. This manuscript covers carbon nanotube history, classification, and applications
