激光显现血潜足迹研究

Study of the development of latent bloody footprint with laser

本文研究了汞溴红试剂喷洒血潜足迹载体表面后,在激光照射下的血迹光致荧光增强效应,根据吸收光谱和色谱分析的实验结果,讨论了荧光增强的原因。并利用这种效应,显现了几种载体上的血潜足迹,取得了满意效果。

The fluorescence enhancement effect for latent bloody footprint on the articles sprayed with mereurochrome reagent under laser illumination is investigated. According to the experimental results from absorption spectra and chromatographic analysis, the source of fluore scence enhancement is discussed. Latent bloody footprints bearing on several kinds of articles are developed, effectively with the enhance fluorescence.
