Fluorescent nitrogen-doped carbon dots (N-CDs) with excellent stability were prepared via single-step hydrothermal carbonization of citric acid (CA) and ethylenediamine (EDA). The as-prepared N-CDs emit blue fluorescence under the excitation of 365[Formula: see text]nm and have a size distribution of 2.80 ± 0.47[Formula: see text]nm with benign size effect. The structure and morphology were further characterized by X-ray photoelectron spectroscopy (XPS) and Fourier transform infrared (FTIR) spectroscopy. It was found that the surface of the N-CDs was successfully functionalized, which presented water solubility and chelation with Fe3+. XRD results display a diffraction peak at 23.9°C, which corresponds to the (002) interlayer spacing of a graphitic structure revealing an amorphous carbon phase. Furthermore, due to good sensitivity, N-CDs were used as probes for Fe3+ detection. The low limit of detection of 0.6[Formula: see text]μM as a fluorescence probe was successfully obtained based on the linear relationship between ([Formula: see text] and concentration of Fe3+ ions. Besides the satisfactory fluorescence, PVA/N-CDs membranes and fluorescent inks demonstrate potential for anti-counterfeiting applications due to its characteristic flexibility, transparency, removability and invisibility under ambient lighting.

“…reported a facile treatment of coriander leaves for preparing BCDs . Honey, black tea, egg white, papaya, goose feathers, and other diverse biomass are widely used to prepare carbon dots for iron ion detection . It is precisely because iron ions are widely studied that their detection limits are getting lower and lower.…”

Carbon dots (CDs) have received much attention due to their superior properties including water solubility, low toxicity, biocompatibility, small size, fluorescence, and ease of modification. The use of a more environmentally friendly method to prepare high‐quality CDs is still an urgent question waiting for solve. The use of renewable, inexpensive, and green biomass resources not only meets the urgent need for large‐scale synthesis biomass CDs (BCDs), but also promotes the development of sustainable applications. In this article, we summarize the representative methods for synthesizing BCDs in green and simple ways using biomass as a carbon source, including hydrothermal carbonization, and microwave, pyrolysis. The prepared BCDs have a uniform particle size distribution and a relatively high throughput, which provide a method to scale up industrial production. Moreover, the integration of specific optical properties, that is, tunable photoluminescence and up‐photoluminescence, has led to remarkable use in bioimaging, sensing, and drug delivery. But the current review is not particularly comprehensive for BCDs. Therefore, we now provide a review focusing on the synthesis, properties, and recent advances in BCDs in biosensing, bioimaging, optoelectronics, and catalytic applications.

“…44 In regards environmental protection, many eco-friendly precursors have been developed to synthesize CQDs from hair, banana juice, pee pollen, and winter melon, etc. [45][46][47][48][49] These sources are highly desirable for achieving a simple, economical, and green synthesis procedure for the preparation of uorescent CQDs. The application of biomass to prepare carbon nanomaterials has been one strong trend to synthesize a surface-passivated material to improve the selectivity by functionalization and enhanced sensitivity to recognize certain analytical species.…”
