Temperature-controlled DCP Fluorescent Probe Based on Hydrogel-immobilized Quantum Dots Composite

A composite was created by incorporating the quantum dot-enhanced SiO₂ nanoparticles within this hydrogel. Based on this composite, a temperature-controlled fluorescent probe for DCP was developed. A meticulous examination of this probe revealed its attributes and factors affecting its performance. By using temperature modulation, the probe was adept at detecting DCP concentrations ranging between 1.0×10⁻⁶ and 9.0×10⁻⁶ mol/L. Such a probe offers remarkable selectivity, repeatability, and robust stability, so that the detection of DCP can be carried out at different temperatures, and a fast, reliable, sensitive and low-cost intelligent detection method is realized.
