Dielectrophoresis (DEP) is one of the methods for uniformly aligning single-walled carbon nanotube (SWCNTs) between designed electrodes. The DEP-fabricated sensors are suitable for the detection of chemical warfare agents (CWAs) due to their sensivitity. However, this sensors has a limitation in selectivity in sensing various CWAs, so we developed thiourea-based receptors to functionalize SWCNTs by diazonium chemistry. In addition, polymeric receptor molecules were also spin-coated on SWCNTs for ensuring the selectivity. The fabricated SWCNT sensors showed good responses and selectivities on the CWAs tested: DMMP (GB simulant), CEPS (simulant of HD), VX and CG, which were further analyzed by PCA and the pattern recognition. |
