Precisely onsite monitoring of hypochlorite (ClO−) is of great significance to guide its rational use, reducing/avoiding its potential threat toward food safety and human health. Considering ClO− could quench fluorescence of curcumin (CCM) by oxidizing the o-methoxyphenol of CCM into benzoquinone, a portable ratiometric fluorescence sensor integrated with smartphone was designed for realizing the visual point-of-care testing (POCT) of ClO−. The amphiphilic phospholipid polymer was used as carrier to wrap curcumin, forming a novel liposome-encapsulated CCM, which provided a scaffold to bind with [Ru(bpy)3]2+ through electrostatic interaction, thus assembling [Ru(bpy)3]2+-functionalized liposome-encapsulated CCM ([Ru(bpy)3]2+@CCM-NPs). Further integrated with smartphone, visual imaging of [Ru(bpy)3]2+@CCM-NPs could be achieved and the accurate onsite detection of ClO− could be realized with a detection limit of 66.31 nM and a linear range of 0.2210 to 80.0 μM. In addition, the sensor could monitor ClO− in real samples with an onsite detection time of ∼154.0 s. 相似文献

本文以本校2005级本科生为调查对象,考察影响大学生四级考试(College English Test Band Four,简称CET-4)CET-4成绩的因素。采用Bootstrap方法与T检验方法,分析得出:来自城市和农村的大学生CET-4成绩存在差异;大一大二四学期英语水平不同的人CET-4成绩存在显著差异;文、理科大学生CET-4成绩也存在差异。进一步,我们运用多元统计中回归分析的方法建立了CET-4成绩的回归模型,并利用Logistic模型对四级通过率进行了预测。 相似文献
