便携式近红外光谱（MicroNIR）结合化学计量学首次研究了作为一种新的工具，现场分析的人手上的爆炸物。与罗马的科学调查部（Carabinieri RIS）合作，开发并验证了一种基于使用特定小型化近红外光谱仪的全新现场方法。从25名志愿者的光谱中获得的近红外区域的反射模式，并优化的基础上，化学计量学工具的预测模型。结果表明，MicroNIR化学计量学方法能够正确识别手中的爆炸物，并且不受基质的复杂性和可变性的影响。这项研究表明，显微近红外化学计量学方法可以被认为是一个有用的，快速的，非破坏性的工具，确定在真实的法医案件中的爆炸物的操作。
Portable near-infrared spectroscopy (MicroNIR) coupled with chemometrics was investigated for the first time as a new tool for the on-site analysis of explosives on human hands. A novel, entirely on-site approach based on the use of a particular miniaturized NIR spectrometer was developed and validated in cooperation with the Scientific Investigation Department (Carabinieri RIS) of Rome. Spectra from 25 volunteers were acquired in the NIR region in reflectance mode, and a prediction model was optimized on the basis of chemometric tools. The results demonstrated the capability of the MicroNIR-Chemometrics approach to correctly identify explosives from hands and not be affected by the complexity and variability of the matrix. This study has shown that the MicroNIR-Chemometrics approach can be considered a useful, fast, nondestructive tool identifying the manipulation of explosives in real forensic cases.
