DNA–single-walled carbon nanotube (SWNT) hybrid fibers are fabricated. Partial debundling and alignment of the nanotubes reduces junction resistances leading to high conductivities. The DNA is effective, as a mechanical binder and for debundling the SWNTs, even when immersed in liquid electrolytes. Therefore, the DNA–SWNT Fibers show excellent supercapacitor behavior and superior actuation performance.
