Studies on the Development of Latent Fingerprints on Paper by the Method of Solid-Medium Ninhydrin YANG Rui-qin;LIU Chao-wen(Department of Forensic Science;Chinese People's Public Security University;Beijing;000;China) 2008(2): 54-57.  Abstract ( )   Fingerprints are considered to be the most valuable and frequent forensic evidence at crime scene. During criminal investigation, investigators search and detect the latent fingerprints with all kinds of skills. The means of detecting fingerprints and their effects play an important role in solving crimes. So the techniques and skills for detecting latent fingerprints are hotspot in forensic science. Ninhydrin is a successful reagent for developing latent fingerprints on porous surfaces. Ninhydrin solutions may be applied by spraying, swabbing, dipping. However, there are several limitations to the ninhydrin method, such as background coloration after treatment, dissolution of the printing ink and its flammable characteristics. Solid-medium ninhydrin method can overcome those disadvantages, avoid the using of ninhydrin development cabinet, develop fingerprints in high speed and break the limitation of detecting prints only on porous surfaces.
