“…This phenomenon shows, therefore, that the synthesized dual‐emissive colorimetric fluorescence probe of the GSH‐CDs could be an appropriate tool for detecting Mn 2+ and Cu 2+ . Compared with previous reports, the GSH‐CDs exhibit higher sensitivity (see Table S1 in the Supporting Information). Most important, the detection of Zn 2+ , Mn 2+ , and Cu 2+ by GSH‐CDs can be achieved simultaneously due to their different responses.…”

Dual‐emissive fluorescent glutathione carbon dots (GSH‐CDs) have been synthesized by a green hydrothermal method and used as a colorimetric fluorescent probe for the multi‐detection of Zn2+, Mn2+, and Cu2+ individually or simultaneously. The GSH‐CDs exhibit dual fluorescence emission at 460 and 683 nm, which results in cyan fluorescence emission under UV light. The dual‐emissive GSH‐CDs can be used as a multifunctional colorimetric fluorescent nanoprobe for precise and quantitative detection of Zn2+, Mn2+, and Cu2+ through a change in the color of the fluorescence. Upon interaction with Zn2+, the fluorescent color of the GSH‐CDs was transformed from cyan to pink. When exposed to Mn2+ or Cu2+, the fluorescence color was transformed from cyan to blue. When the three ions were present simultaneously, the cyan fluorescence emission changed to a nattier blue. The minimum limits of detection (LODs) for Zn2+, Mn2+, and Cu2+ were calculated to be 9.64, 3.24, and 1.7 nm, respectively. As far as we know, this is the first report of the use of dual‐emissive carbon dots for the multi‐detection of heavy‐metal ions. Moreover, the multi‐detection of Zn2+, Mn2+, and Cu2+ in real environmental water by GSH‐CDs was also investigated. In addition the GSH‐CDs can be applied in cell imaging.

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.

“…Nonetheless, the above methods usually involve chemical reagents and complicated postprocessing steps. On account of facility and economy, more researchers adopt a hydrothermal method to prepare CDs from kinds of biomass, such as orange juice, silkworm chrysalis, shrimp shell, and so on . However, rarely these methods have been investigated and reach a high synthetic yield of CDs, which sets back their scale‐up manufacture.…”

in the presence of water vapor with argon as carrier gas, [1] and electrochemically etched carbon fibers at a constant potential for several hours. [14] Nonetheless, the above methods usually involve chemical reagents and complicated postprocessing steps. On account of facility and economy, more researchers adopt a hydrothermal method to prepare CDs from kinds of biomass, such as orange juice, [15] silkworm chrysalis, [16] shrimp shell, [17,18] and so on. [19,20] However, rarely these methods have been investigated and reach a high synthetic yield of CDs, which sets back their scale-up manufacture. Only a few papers concerned the yield, [21,22] and the productivity of CDs is generally still at a low level (≤30%) as shown in Table S1 of the Supporting Information. Therefore, it should be noted that the strategy of macroscopic preparation of CDs is important for its future widespread utilities.As we all know, yeast extract powders (YEPs) are made by yeasts-a kind of single-celled organisms. As an economical and nutrient-rich [23,24] matter (including peptides, amino acids, minerals, and B-complex vitamins), YEPs are frequently employed in the food field. There are several significant reasons why we chose YEP as carbon source to produce CDs. The most important of all is that the inexpensive raw materials are needed for large-scale production of CDs. Therefore, YEP as carbon source only costs 0.0376 RMB g −1 , which is cheaper than the previous work. [11] Second, the yield of CDs made from YEP can reach up to 65.8%, which could be desired for scale manufacture. Third, the fluorescence quantum yield (QY) of CDs can attain 3.4-13.7%, which is enough for applications in various fields. [25][26][27] Shape memory materials as typical smart materials, which can change from a temporary shape to a permanent shape under an external stimulus, were potentially applied in sensors, [28] actuators, [29] and biomedicine. [30] In a nutshell, typical shape memory materials can usually be a permanent shape in nature, and then it can be defined by an applied force, and form a temporary shape. Accordingly, when an external stimulus is carried out, the temporary shape will return to the permanent shape. Here, it is also called stimuli-responsive shape memory material. [31,32] However, most of these shape memory materials Fluorescent carbon dots (CDs) have drawn lots of attention for their excellent properties and broad applications. However, rarely hydrothermal methods of preparation have been investigated and reach a high synthetic yield of CDs, which limits their scale-up production. In this work, a large-scale one-step process is shown to prepare CDs from yeast extract powder (called y-CDs) for the first time and the yield of CDs can reach up to 65.8%. The optical properties and morphology of the y-CDs are characterized. On account of good water solubility and high yield of y-CDs, the application of the reprepared y-CDs/polyvinyl alcohol (PVA) as fluorescent shape memory material is explored. It turns out that the reprepared y-CDs/PVA...
