茚三酮是显现渗透性客体上汗潜手印的主要试剂之一,茚三酮类似物主要由茚三酮同系物、茚二酮、DFO等组成.茚三酮及其类似物在我国刑事技术部门主要以溶液法进行使用,随着越来越多的渗透性疑难客体(如热敏纸、卫生纸等)遗留在犯罪现场,传统溶液法应用受到局限.本文旨在对茚三酮及其类似物显现汗潜手印进行综述,结合当前存在的实际问题,提出未来研究展望.%Ninhydrin is recognized as the major reagent for the detection of latent fingerprint on porous surfaces. Ninhydrin analogues mainly consist of ninhydrin homologues,Indenedione,DFO and so on. Ninhydrin and its analogues are mainly used by the solution method in the criminal technology department in China. However,more and more difficult objects(such as thermal paper,toilet pa-per,etc. )left at the crime scenes,the traditional ninhydrin applications have been limited. Progress of ninhydrin and its analogues technology in latent fingerprint development are reviewed,this work combined the existing problems of ninhydrin analogues technolo-gy in latent fingerprint development and put forward the prospect of future research.
