Abstract

Background:: In the paper, Boletus Brucella was used as carbon source material to prepare carbon dots (CDs) by one-step hydrothermal method. The CDs had high quantum yield and high photostability. Methods:: A range of characterization studies were conducted on CDs, and the results showed that the average particle size of CDs was 5 nm, emitting blue fluorescence. The optimal excitation wavelength was 337 nm, and the emission wavelength was 440 nm. Results:: Based on the static quenching, the fluorescence of CDs could be effectively quenched by VB2. Therefore, a highly sensitive and selective fluorescent probe for detecting VB2 was constructed. The CDs were successfully used to detect tablets, human blood, and urine. Conclusion:: The recovery rate of VB2 was 97.55~99.45%, and the relative standard deviation was 1.29~3.76 (n=3). conclusion: The recovery rate of VB2 was 97.55~99.45%, and the relative standard deviation was 1.29~3.76 (n=3).

水热合成布鲁氏菌衍生碳量子点作为荧光探针检测维生素B2

背景:本文以布鲁氏杆菌为碳源材料，采用一步水热法制备碳点(CDs)。该CDs具有高量子产率和光稳定性。方法:对CDs进行了一系列表征研究，结果表明CDs的平均粒径为5 nm，发出蓝色荧光。最佳激发波长为337 nm，发射波长为440 nm。结果:在静态猝灭的基础上，VB2能有效猝灭CDs的荧光。为此，构建了一种高灵敏度、高选择性的VB2荧光探针。该方法成功地用于药片、人体血液和尿液的检测。结论:VB2的回收率为97.55~99.45%，相对标准偏差为1.29~3.76 (n=3)。结论:VB2的回收率为97.55~99.45%，相对标准偏差为1.29~3.76 (n=3)。
