研究目的
To review the spectroscopic techniques used or being researched for the non-destructive, rapid, and user-friendly detection and identification of body fluids found at crime scenes.
研究成果
Spectroscopic techniques, particularly HSI, FTIR, and Raman spectroscopy, show promise for the non-destructive, rapid, and selective identification of body fluids in forensic science. However, further research is needed to address unsolved aspects such as the influence of substrates and mixtures of body fluids, and to optimize these techniques for real forensic applications.
研究不足
The paper highlights the limitations of current spectroscopic techniques, including the lack of selectivity of UV-Vis light sources, the influence of fabric material and color on IR or Raman spectra, and the challenges in identifying mixtures of body fluids. It also notes the need for further research to optimize and validate these techniques for real forensic cases.
