Semiconducting carbon nanotube fibers for electrochemical biosensor platforms

open access: yesMaterials & Design, 2020
We report the fabrication of semiconducting single-walled carbon nanotube (sc-SWNT) fibers via wet-spinning for electrochemical biosensor platforms. SWNTs were purified using thermal and acid treatments and separated into metallic SWNTs and sc-SWNTs. The
