摘　　要：传统汗潜指印显现技术在改进、更新的同时,涌现出许多新的技术与方法,主要是将新材料、光谱法、质谱法、电化学方法、生物技术等应用于汗潜指印显现中。新兴技术在某些方面克服了传统技术的缺陷,弥补了其不足之处,在显现灵敏度、显现条件、显现效率与效果方面表现突出,尤其是在陈旧、痕量级汗潜指印显现打破了传统技术的瓶颈,标志着汗潜指印显现技术迈入了一个新纪元。虽然新技术在诸多方面崭露头角,但过度依赖仪器设备与试剂,操作专业化要求高,无法在短时间内完全取代传统技术。本文综述了新技术在汗潜指印显现中应用的研究进展,归纳总结了其不足之处,并展望未来汗潜指印显现技术的发展方向。Over the last 100 years, the methods for traditional visualization of latent ifngerprints have been improved, and meanwhile, many new techniques and approaches have been applied in this area. In general, the latest technology mainly includes new material, electrochemiluminescence imaging, biotechnology, spectral imaging, mass spectrometry, etc. The novel visualization technology overcomes the limitation of the traditional ones in many aspects of visualization sensitivity and efifciency, especially wins a lot of applauses when dealing with the old latent ifngerprints at trace level, marking the beginning of a new era of latent ifngerprint visualization. However, the new technology over-relies on some expensive equipment and reagents, and requires high demanding practices. As a result, a great deal of work has to be done further, to make sure that it can completely replace the traditional methods in more practical term in the foreseeable future. This paper reviews the research progress in the application of new technology, and looks forward to the future development of latent ifngerprint visualization technology.
