Nicotine is highly addictive and harmful. It is one of the main active ingredients in tobacco and a major pollutant in environmental tobacco smoke. Thus, it is important to detect the nicotine content in tobacco and to monitor the nicotine content in environmental tobacco smoke. However, until present, there still has been no effective device for on-site determination of nicotine content in tobacco and environmental tobacco smoke. In this work, a portable device is fabricated for sensitive on-site evaluation of nicotine in tobacco and environmental tobacco smoke based on surface-enhanced Raman scattering (SERS). The weight of the entire device is less than 1 kg, and it uses a chargeable battery to drive both the pump and the Raman spectrometer. The total analysis time can be completed within 3-5 min. Thus, it has great potential for on-site analysis of nicotine in tobacco and environmental tobacco smoke.
尼古丁具有很强的成瘾性和危害性。它是烟草中的主要活性成分之一，也是环境烟草烟雾中的主要污染物。因此，检测烟草中的尼古丁含量和监测环境烟草烟雾中的尼古丁含量非常重要。然而，到目前为止，还没有用于现场测定烟草和环境烟草烟雾中尼古丁含量的有效装置。在这项工作中，基于表面增强拉曼散射（SERS），我们制备了一种用于现场灵敏评估烟草和环境烟草烟雾中尼古丁的便携式装置。整个装置的重量小于 1 公斤，它使用可充电电池为泵和拉曼光谱仪供电。总分析时间可在 3-5 分钟内完成。因此，它在现场分析烟草和环境烟草烟雾中的尼古丁方面具有很大的潜力。
