“…Recently, nanoparticle-based fluorescence probes have been developed to widely detect Cu 2+ owing to their high sensitivity and simplicity. [30][31][32][33][34][35] For example, Zhao et al 36 synthesized highly luminescent, surface-different, N-CDs using ionic liquids as precursors for the detection of Cu 2+ and cell imaging. Tian et al 37 developed a highly efficient fluorosensor based on ultrathin graphitic carbon nitride (g-C 3 N 4 ) nanosheets for the detection of Cu 2+ .…”

Nitrogen-doped carbon dots were synthesized using citric acid monohydrate and glutathione as raw materials. The synthesized nitrogen-doped carbon dots were characterized by multiple analytical techniques, including transmission electron microscopy, Fourier transform infrared spectroscopy, ultraviolet–visible absorption spectroscopy, X-ray photoelectron spectroscopy, X-ray diffractometry, and fluorescence spectra. The fluorescence intensity of the nitrogen-doped carbon dots gradually quenched with different concentrations of Cu2+ ions. The effect of the pH value, the nitrogen-doped carbon dot concentration, and the reaction time on the fluorescence intensity of the N-CDs-Cu2+ system was investigated, and the experimental conditions were optimized. A rapid and sensitive method for the determination of Cu2+ ions was established that exhibited a good linearity in the concentration range 0.20–200.0 μM with a detection limit of 0.27 nM. Meanwhile, the fluorescence quenching mechanism of the interaction between nitrogen-doped carbon dots and Cu2+ was preliminarily discussed. The method was used to detect trace Cu2+ in tap water and lake water, with recoveries ranging from 98.1% to 102.0%. Furthermore, due to low cytotoxicity and good biocompatibility, nitrogen-doped carbon dots as a probe were also successfully used in bioimaging.

“…In the aqueous phase, the C-dots provided excellent fluorescent characteristics as well as thermodynamic consistency [ 56 ]. Naik et al synthesized nitrogen-doped carbon dots by using the hydrothermal process and made a decent naked eye fluorescence probe for dopamine sensing [ 57 ]. They obtained a linear range of 2–20 μg/mL along with a detection limit as low as 1.97 μg/mL.…”
