Fingerprint can directly identify the person, and it is one of the most important physical evidence in the criminal scene. Fingerprint has always been considered as the "head of physical evidence" and plays an important role in the investigation and court proceedings. However, the fingerprint on the relevant object can not be directly observed by human eyes in actual cases, so it is also called "latent fingerprint". Although the latent fingerprint development technology has made great progress, it still faces many difficulties in the aspects of nondestructive, sensitive and efficient. And, it will bring serious difficulties to the subsequent fingerprint identification work for the criminal technicians. Therefore, it is of great significance to develop highly selective, sensitive and convenient latent fingerprint developing materials or techniques. In view of this, on the basis of the research achievements at home and abroad, the application of traditional organic materials widely used in latent fingerprint development and the new fluorescent organic materials is briefly reviewed, such as aggregation induced emission materials, conjugated polymer materials and other organic fluorescent materials, in latent fingerprint development in recent ten years. The design concept of related organic materials and the mechanism of developing latent fingerprints are summarized. Finally, the existing problems are discussed, and the future development trend of organic materials in developing latent fingerprints is prospected.
