Carbon nanotubes are tiny, cylindrical structures made of carbon atoms arranged in a hexagonal pattern. They are incredibly strong and lightweight, making them useful in various applications, from electronics to materials science. Their unique properties allow them to conduct electricity and heat efficiently, which is why researchers are excited about their potential in developing advanced technologies. These remarkable structures can be thought of as rolled-up sheets of graphene, another form of carbon. Due to their versatility, carbon nanotubes are being explored for use in nanotechnology, composite materials, and even in medical applications like drug delivery systems.
