Abstract

The widespread use of smartphones and related tools is extending their applications in several fields. Herein, we report a reusable smartphone coupled portable detection system for the sensing of sub-ppm level of a nerve agent mimic (dimethylmethylphosphonate) in the gas phase. The detection system is based on multiple hydrogen-bond interactions of the vapor analyte with an ad-hoc functionalized Bodipy chromophore scaffold. The multitopic approach used for the molecular recognition of DMMP leads to the highest binding constant values, high selectivity, and low limits of detection.

摘要

智能手机及相关工具的广泛使用正在拓展它们在多个领域的应用。在此，我们报告一种可重复使用的、与智能手机相连的便携式检测系统，用于检测气相中痕量水平的神经毒剂模拟物（甲基膦酸二甲酯）。该检测系统基于蒸汽分析物与一种经过特殊功能化的硼二吡咯发色团支架之间的多重氢键相互作用。用于甲基膦酸二甲酯分子识别的多靶点方法产生了最高的结合常数、高选择性和低检测限。
