Development of Sulfur and Nitrogen‐Doped Fluorescent Carbon Quantum Dots for Hydroquinone Sensing

= 0.998), and exhibited excellent selectivity toward HQ. The application and reliability associated with fluorescent probes were demonstrated for the examination of HQ in real water samples. The results found that the one-pot hydrothermal synthesis method shows high sensitivity, selectivity, and accuracy for the detection of HQ, highlighting its potential for environmental monitoring and practical applications.
