便携式化学传感系统将样品预浓缩、分离和检测以及无线通信功能集成到紧凑、可穿戴的格式中，可以对环境中的挥发性有机化合物进行连续和实时的监测。这种传感方式依赖于涂有分子印迹聚合物的音叉，这种聚合物与样品预浓缩相结合，提供了低至十亿分之一级的选择性检测。使用毛细管柱，即使在有干扰物存在的情况下，也可以在这些高度灵敏的水平上检测复杂混合物的各个组分。无线功能便于使用配对的智能手机作为用户界面，以及用于额外处理和存储测量数据的工具。这种综合方法为个人暴露评估提供了一个具有成本效益和可靠的平台。
A portable chemical sensing system that integrates sample preconcentration, separation and detection as well as wireless communication functionalities into a compact, wearable format can provide continuous and real-time monitoring of volatile organic compounds in the environment. The sensing modality relies on tuning forks coated with molecularly imprinted polymers that, in conjunction with sample preconcentration, offer selective detection down to parts-per-billion levels. The use of capillary columns allows individual components of complex mixtures to be detected at these highly sensitive levels even in the presence of interferents. The wireless capability facilitates the utilization of a paired smartphone as the user interface as well as a vehicle for additional processing and storage of the measured data. This integrated approach offers a cost-effective and reliable platform for personal exposure assessment.
