Capillary Sensors Composed of CdTe Quantum Dots for Real-Time In Situ Detection of Cu<sup>2+</sup>
CdTe colloidal quantum dots (CQDs)
coated with glutathione (GSH)
were prepared by aqueous synthesis. Based on the fluorescence selective
quenching of CdTe CQDs in the presence of Cu2+, the CdTe
CQDs were applied for ultrasensitive Cu2+ sensing. The
detection limit of Cu2+ concentration was 0.055 μM.
In order to realize real-time and rapid on-site detection, a capillary
sensor composed of CdTe CQDs was prepared, and after drying at room
temperature, heating at high temperature, and laser processing, the
sensor achieved good response time and detection accuracy results.
The detection of 1 × 10–5 mol/L Cu2+ concentration can be realized in 5–6 s. Moreover, the detection
only needs to be carried out under an ultraviolet lamp, the cost of
the sensor is low, and the detection method is very simple. The sensor
requires only 3 μL of solution to be tested and can complete
the detection, which not only saves the solution to be tested but
also greatly improves the limit of the detection environment. A capillary
sensor is of great significance for the real-time detection of natural
environment and industrial wastewater
