“…在适用性方面, Williams 等 [89] 比较了 CTF 与真空金属沉积(VMD)两种相似技术在汗液和血液指印方面的显现效果, 发现 CTF 不直接作用于分泌物、不易受分泌物的量或沉积压力的影响, 且其适用范围更广; 此外, CTF 方法可同时可视化非多孔基底上血和非血部分的指印, 避免了不同检测方法间的相互干扰, 检测效果优于其他几类蛋白质染色类方法 [90] . 在遗传物质兼容性方面, 据 Plazibat 等 [91] 报道, CTF 技术在处理唾液指印和血液指印时, 不会影响后续的 STR 图谱分析; Goecker 等 [92] 也证实了 CTF 技术不会导致明显的 DNA 降解. 2020 年, Tiedge 等 [93] 通过大规模平行测序和 STR 分析, 亦发现蒸发物材料的 DNA 分析未受抑制.…”

Blood fingermark, as a common piece of evidence at crime scenes, plays an important role in personal recognition, crime scene reconstruction, and criminal investigation. In recent years, with the deep integration of blood fingermark detection and new reagents, advanced materials, modern analytical methods as well as immunological techniques, the sensitivity, specificity, contrast and applicability of blood fingermark detection have been continuously improved. Moreover, greater breakthroughs have been made in the analysis of endogenous and exogenous fingermark components, the compatibility of touch DNA, and identification of fingermark aging time. This paper outlines the research progress of blood fingermark detection technology both domestically and internationally, which includes not only traditional chemical reagents based on the mechanism of haem catalysis, protein staining and amino acid reaction, but also emerging methods based on novel materials and devices. A brief analysis of the advantages and disadvantages of each method is discussed, and finally, a prospective outlook is presented on the challenges and future prospects of existing techniques, aiming to offer guidance for scholars and practitioners in forensic science.
