Carbon nanotubes, particularly short single-walled ones, are widely used in various advanced applications due to their unique properties. In electronics, they serve as conductive components in transistors, sensors, and flexible displays, offering high electrical conductivity and mechanical strength. They are also incorporated into composite materials to enhance strength, durability, and lightweight properties, making them ideal for aerospace, automotive, and sports equipment. In energy storage, they are used in batteries and supercapacitors to improve charge capacity and efficiency. Additionally, their high surface area and chemical stability make them suitable for use in filtration systems, water purification, and gas storage. In biomedical applications, they are explored for drug delivery systems, tissue engineering, and biosensors due to their biocompatibility and ability to interact with biological molecules.
