dc.description.abstract | We fabricated carbon nanotube (CNT) based chemical sensors for marine applications by photolithography process, where the electrodes were insulated by photoresist exposing only the carbon nanotube sensing section (2 mu m gap width) for detection of ammonium ions (NH4+) in 35 parts per thousand NaCl solution used as artificial seawater environment. The l-V curve of the CNT sensor was measured by sweeping the source-drain voltage from -3 to 3 V and the on/off ratio of the CNT sensor was measured to be 20 when the gate voltage was swept from -5 to 5 V and from these results the CNTs were found to appear as a p-type semiconductor. All of the cocktail solutions prepared for experiment were measured to have similar to pH 6 which implied 99.9% of NH4+ remained ionized. We successfully detected 10, 100, 1000 nM (0.18, 1.8, 18 ppb) concentration of NH4+ in 35 parts per thousand NaCl solutions by using the CNT sensor. | - |
