Cadmium selenide (CdSe) quantum dots (QDs) were synthesized by water phase synthesis method using 3-mercaptopropionic acid (3-MPA) as a stabilizer, and they were applied to the detection of copper ions (Cu2+). The results showed that CdSe QDs have excellent selectivity and sensitivity toward Cu2+. The fluorescence intensity of CdSe QDs decreased with the increase of Cu2+ concentration. The linear range was from 30 nM to 3 μM, and the detection limit was 30 nM. Furthermore, CdSe QDs were used for detecting the concentration of Cu2+ in oysters. The content of Cu2+ was 40.91 mg/kg, which was close to the one measured via flame atomic absorption spectrometry (FAAS), and the relative error was 1.81%. Therefore, CdSe QDs have a wide application prospect in the rapid detection of copper ions in food.

Cadmium Selenide Quantum Dots

A novel Cadmium selenide Quantum dots MWCNTs nanocomposite modified electrode was achieved by simple drop casting method and its application towards the quantitative determination of epinephrine. The Cadmium selenide Quantum Dots was characterized by transmission electron microscopy and MWCNT was characterized by scanning electron microscopy. The electrochemical characteristics of the modified electrode were studied using cyclic voltammetry. The voltammetric response of the modified electrode was higher than that of the MWCNT and bare electrodes. The modified electrode exhibits excellent electrocatalytic activity towards the oxidation of epinephrine by enhancing its oxidation current in 0.1M phosphate buffer solution. The determination range of epinephrine is from 0.16 μM to 14 μM and the detection limit was 0.05 μM (S/N = 3). The proposed modified electrode exhibited good stability and reproducibility.
