基于细胞衍生荧光碳点的葡萄糖比色及荧光测定
Colorimetric and Fluorescence Determination of Glucose Based on Cell-derived Fluorescent Carbon Dots
以肿瘤细胞为原料, 通过一步水热法合成了细胞衍生荧光碳点(CDs). 研究结果表明, 该CDs具有优异的类过氧化物酶催化活性, 能够催化过氧化氢反应生成羟基自由基. 基于此, 利用葡萄糖氧化产生的过氧化氢 及CDs的类过氧化物酶性能氧化对苯二胺(p-Phenylenediamine, PPD)底物生成氧化产物PPDox[2,5-Diamino- N,N′-di-(4-aminophenyl)-2,5-cyclohexadiene-1,4-diimine]. 并通过PPDox对荧光CDs的内滤效应, 实现了葡萄糖的比色与荧光双模式检测. 比色法与荧光法检测葡萄糖的检出限分别为41和13 µmol/L. 反应过程中, CDs具备双重功能, 既可作为类过氧化物酶催化过氧化氢产生羟基自由基用于氧化PPD, 又可作为荧光指示剂, 通过内滤效应指示葡萄糖的浓度变化.
Cell derived fluorescent carbon points(CDs) were synthesized via one step hydrothermal method. It is found that the CDs have excellent peroxide-like catalytic activity, which can catalyze the hydrogen peroxide to produce hydroxyl radical. Based on this, the hydrogen peroxide produced by glucose oxidation and CDs could consecutively oxidize p-phenylenediamine(PPD) to produce PPDox[2,5-Diamino-N,N′-di-(4-aminophenyl)-2,5-cyclohexadiene-1,4-diimine]. By virtue of the inner filer effect of PPDox on CDs, a dual-mode colorimetric and fluorescent detection of glucose was establised. The limit of detection of the present assay are 41 µmol/L and 13 µmol/L for the colorimetric method and the fluorescence method, respectively. In this work, CDs can not only be used as a peroxide-like enzyme to catalyze hydrogen peroxide to produce hydroxyl radical for PPD oxidation, but also be used as a fluorescent indicator to indicate the change of glucose concentration through the internal filtration effect.
