In this work, we report a two-member fluorescence array sensor for the effective discrimination of five classes of explosives. This smallest array sensor is composed of tricarbazole-based nanofibers (sensor member 1) and nanoribbons (sensor member 2) deposited as two film bands in a quartz tube. On the basis of a simple comparison of the resulting fluorescence quenching ratios between two sensor members and the response reversibility upon exposure to vaporized explosives, five classes of explosives can be sensitively detected and easily discriminated. This array sensor that has only two sensor members and no complex data analysis represents a new design way for discrimination of a broad class of explosives.
在这项工作中，我们报告了一种由两个成员组成的荧光阵列传感器，可有效区分五类爆炸物。这个最小的阵列传感器由基于三咔唑的纳米纤维（传感器成员 1）和纳米带（传感器成员 2）组成，沉积在石英管中的两个薄膜带中。基于两个传感器成员之间产生的荧光猝灭比的简单比较，以及暴露于蒸气爆炸物后的响应可逆性，能够灵敏地检测和轻松区分五类爆炸物。这个只有两个传感器成员且没有复杂数据分析的阵列传感器为广泛类别的爆炸物的区分提供了一种新的设计方法。
