Their quantum yield is higher than 54%. A sensitive electrochemiluminescence (ECL) method was established based on the modification of the composite of the QDs, carbon nanotubes and chitosan on indium tin oxide glass. The sensor displays efficient and stable anodic ECL which is quenched by dopamine. A respective sensor was designed that responds to dopamine linearly in the range of 50pM to 10nM, and the detection limit is 24pM. Dopamine was determined with this sensor in spiked cerebro-spinal fluid with average recoveries of 95.7%. Figure The CdTe quantum dots have been synthesized and therefore developed an electrochemiluminescent sensor based on immobilizing its composite with carbon nanotubes and chitosan on indium tin oxide glass. The sensor responded toward dopamine linearly in the range of 50pM to 10nM with a detection limit of 24pM.
