Purified amino-functionalized single-walled carbon nanotubes (SWNTs) are widely used in various advanced applications due to their unique properties. In the field of electronics, they are utilized to create high-performance transistors, sensors, and conductive films, enhancing device efficiency and sensitivity. In energy storage, they serve as key components in lithium-ion batteries and supercapacitors, improving charge capacity and conductivity.

In biomedical applications, these nanotubes are employed for drug delivery systems, where their functionalized surface allows targeted delivery of therapeutic agents. They are also used in tissue engineering scaffolds to promote cell growth and regeneration. Additionally, in composite materials, they reinforce polymers, metals, and ceramics, resulting in stronger, lighter, and more durable products. Their ability to absorb and emit light makes them valuable in optoelectronic devices and photothermal therapy for cancer treatment.
