摘要
指印残留物是指纹上汗孔分泌的汗液接触客体产生的多种物质,主要为指尖分泌的化学成分,这些化学成分中的某些特征成分能够反映指印供体的相关信息。指印残留物的分析有多种方法,主要包括质谱及其联用方法,光谱方法和免疫荧光技术。指印残留物的研究与检验可以提供侦查方向,可以对案件的侦破和法庭诉讼提供科学依据。
Fingerprint residues are a variety of substances produced by the exposure of sweat secreted from sweat pore of fingerprint on objects surface,which refer mainly the chemical composition of the fingertips.These chemical constituents can reflect the relevant information of the fingerprint donor.There are a number of methods of analyzing fingerprint residues,including mass spectrum and the linked way,spectrum and immune fluorescence technique.It is possible for the research and testing of fingerprint residues to provide scientific evidence for the detections of case and court proceedings.
