Abstract
It is an ongoing and imperative need to monitor food colorants, for unsafe food is a terrifying threat to human health and economy. Here new Na-Ca-Cl-doped carbon dots (CDs) was fabricated by hydrothermal treatment of Miswak and m-phenylenediamine (mPD). The CDs were green-emitting with three distinctive emission centers, displaying a high quantum yield of 47 %. The CDs were able to assess erythrosine in the triple channels based on their fluorescence quenching by erythrosine because of the inner filter effect, displaying high sensitivity and selectivity. Also, the quantitative measurement of erythrosine utilizing the CDs was realized in food samples and in living cells with admirable fluorescence stability and appealing biocompatibility, representing the first report on exploiting CDs for erythrosine sensing in living cells. Collectively, the CDs provide a simple efficient platform for erythrosine sensing in solutions, food samples, and living cells, broadening the implements of CDs as bioprobes for food colorants.
由于不安全的食品对人类健康和经济都是一个可怕的威胁，因此对食品着色剂进行监测是一项持续而迫切的需求。在这里，通过对 Miswak 和间苯二胺（mPD）进行水热处理，制备出了掺杂 Na-Ca-Cl 的新型碳点（CD）。这种碳点具有三个独特的绿色发射中心，量子产率高达 47%。由于内滤光片效应，CD 能够根据其荧光被赤藓红淬灭的情况来评估三重通道中的赤藓红，具有很高的灵敏度和选择性。此外，利用这种 CD 在食品样品和活细胞中实现了对酪氨酸的定量测量，并具有令人赞叹的荧光稳定性和良好的生物相容性，这是利用 CD 在活细胞中进行酪氨酸传感的首次报道。总之，CD 为溶液、食品样品和活细胞中的酪氨酸传感提供了一个简单高效的平台，拓宽了 CD 作为食品着色剂生物探针的应用领域。
期刊介绍：
The Journal of Molecular Structure is dedicated to the publication of full-length articles and review papers, providing important new structural information on all types of chemical species including:
• Stable and unstable molecules in all types of environments (vapour, molecular beam, liquid, solution, liquid crystal, solid state, matrix-isolated, surface-absorbed etc.)
• Chemical intermediates
• Molecules in excited states
• Biological molecules
• Polymers.
The methods used may include any combination of spectroscopic and non-spectroscopic techniques, for example:
• Infrared spectroscopy (mid, far, near)
• Raman spectroscopy and non-linear Raman methods (CARS, etc.)
• Electronic absorption spectroscopy
• Optical rotatory dispersion and circular dichroism
• Fluorescence and phosphorescence techniques
• Electron spectroscopies (PES, XPS), EXAFS, etc.
• Microwave spectroscopy
• Electron diffraction
• NMR and ESR spectroscopies
• Mössbauer spectroscopy
• X-ray crystallography
• Charge Density Analyses
• Computational Studies (supplementing experimental methods)
We encourage publications combining theoretical and experimental approaches. The structural insights gained by the studies should be correlated with the properties, activity and/ or reactivity of the molecule under investigation and the relevance of this molecule and its implications should be discussed.
