Single Walled Carbon Nanotubes (SWCNTs) consist of a single layer of graphite having a cylindrical shape. Because of their electric properties, they are the most suitable candidate for miniaturizing electronics. They are efficient to be used as excellent conductors in electric wires. SWCNTs are also used for antimicrobial activity. Other applications include its incorporation in electro spun polysulfone nanofibers, having increased antimicrobial capability. It can also be used as additives in polymers, flat panel display, lithium-ion battery anode, and hydrogen storage.
