Abstract :
The deoxyribonucleic acid (DNA)-coated multi-walled carbon nanotube (MWNT) hybrid fibers were fabricated by wet-spinning method. The fibers were made up with entangled nanowire networks of DNA-coated MWNTs, and it shows a strain of ∼0.15% as electrochemical actuators under low potential cycling between 0 and −0.9 V versus Ag/AgCl in 2 M NaCl solution. The fibers also show good electric conductivity (∼60 S/cm) and capacitance (50 ± 5 F/g) behaviors. Based on the appropriation of its electro-chemo-mechanical systems, the DNA/MWNT fiber can be one of the new intelligent materials for biomedical application.
