Carbon nanotube/polymer composite electrodes for flexible, attachable electrochemical DNA sensors
Abstract(#br)All-solution-processed, easily-made, flexible multi-walled carbon nanotube (MWCNT)/polydimethylsiloxane (PDMS)-based electrodes were fabricated and used for electrochemical DNA sensors. These electrodes could serve as a recognition layer for DNA, without any surface modification, through π–π interactions between the MWCNTs and DNA, greatly simplifying the fabrication process for DNA sensors.
