The development of sensors for the detection of triacetone triperoxide (TATP) has attracted great attention. Here, we constructed a low-cost, portable, reusable, visible paper-based fluorescent sensor for the sensitive detection of TATP via vapor sampling. Under optimized conditions, the fluorescent film showed a high sensitivity to TATP with a detection limit of lower than 0.5 μg mL-1 in air. The linear range of the response is from 0.5 to 8.0 μg mL-1. In addition, the paper-based sensor exhibited high selectivity to TATP. The presence of potential interferents showed little effect on sensing. Moreover, sensing is fully reversible. Fortunately, the test can also be conducted in a visualized way.
用于检测三过氧化三丙酮（TATP）的传感器的发展引起了极大的关注。在这里，我们构建了一种低成本、便携式、可重复使用的可见型纸质荧光传感器，通过蒸气采样实现对 TATP 的灵敏检测。在优化条件下，荧光膜对 TATP 具有很高的灵敏度，空气中的检测限低于 0.5μg mL-1。响应的线性范围为 0.5 至 8.0μg mL-1。此外，基于纸张的传感器对 TATP 表现出很高的选择性。潜在干扰物的存在对感测几乎没有影响。此外，感测是完全可逆的。幸运的是，测试也可以以可视化的方式进行。
