“…Some ions quench the fluorescence of BCDs, which is the fundamental principle for the development of sensors for these ions, including Fe 3+ , Pb 2+ , Hg 2+ , CN − , and PO 4 3− . Fe 3+ are the most common detected ions, since the functional groups such as amino groups, carboxyl groups, and hydroxyl groups are generally present on the surface of BCD, they can be effectively combined with iron ions, resulting in fluorescence quenching.…”

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.

“…On the basis of other research, Kumar et al. synthesized BCDs using the leaves of Ocimum sanctum as a carbon source, and the BCDs have outstanding selectivity and sensitivity toward Pb 2+ , with a detection limit of 0.59 nmoL•L ‐1 m and a linear detection range from 0.01 to 1.0 μmoL•L ‐1 m.…”

Natural‐Product‐Derived Carbon Dots: From Natural Products to Functional Materials

et al. 2017

Nature provides an almost limitless supply of sources that inspire scientists to develop new materials with novel applications and less of an environmental impact. Recently, much attention has been focused on preparing natural‐product‐derived carbon dots (NCDs), because natural products have several advantages. First, natural products are renewable and have good biocompatibility. Second, natural products contain heteroatoms, which facilitate the fabrication of heteroatom‐doped NCDs without the addition of an external heteroatom source. Finally, some natural products can be used to prepare NCDs in ways that are very green and simple relative to traditional methods for the preparation of carbon dots from man‐made carbon sources. NCDs have shown tremendous potential in many fields, including biosensing, bioimaging, optoelectronics, and photocatalysis. This Review addresses recent progress in the synthesis, properties, and applications of NCDs. The challenges and future direction of research on NCD‐based materials in this booming field are also discussed.

“…Other studies also reported the strongest photoluminescence intensity in a neutral pH. Moreover, fluorescence decreased in both acid and alkaline conditions (Alam et al, 2015[ 1 ]; Kumar et al, 2018[ 21 ]), although increase in fluorescent intensity with increase in pH has also been reported (Zhong et al, 2016[ 54 ]).…”
