Real-time sensing of chemical warfare agents by optical sensors is today a crucial target to prevent terroristic attacks by chemical weapons. Here the synthesis, characterization and detection properties of a new sensor, based on covalently functionalized carbon nanoparticles, are reported. This nanosensor exploits noncovalent interactions, in particular hydrogen bonds, to detect DMMP, a simulant of nerve agents. The nanostructure of the sensor combined with the supramolecular sensing approach leads to high binding constant affinity, high selectivity and the possibility to reuse the sensor.
通过光学传感器实时感测化学战剂是今天防止化学武器恐怖袭击的一个关键目标。本文报道了一种新传感器的合成、表征和检测性能，该传感器基于共价功能化的碳纳米粒子。这种纳米传感器利用非共价相互作用，特别是氢键，来检测神经毒剂模拟物 DMMP。传感器的纳米结构与超分子传感方法相结合，导致高结合常数亲和力、高选择性和可重复使用传感器的可能性。
