The currently used methods of fingerprint detection may be classified into two categories: those which are dependent on the adherence of inert materials to fingerprint residues (powder methods), and those which rely on chemical interaction of a detection reagent with specific components of the latent print (for example, ninhydrin method). Both classes, in fact all conventional fingerprint detection methods, require a chemical or physical treatment of the exhibit under examination. 

A Portable Fingerprint Detection Apparatus By Using Laser Beam

A laser assisted fluorescence method followed by high-speed image processing has been newly developed for the rapid in-situ detection of latent prints on several kinds of surfaces. It is particularly

TV system for detection of latent fingerprints

A newly developed portable TV system for detecting a latent fingerprint is described, suited for field reconnaissance of cases as well as for laboratory testing.


The chemical substances of perspiration found in latent fingerprint residue may hold the key for dating latent fingerprints because of the variation in the quantity of the major components with time.

Inherent Fluorescence Detection of Latent Fingermarks by Homemade Shortwave Ultraviolet Laser

Experimental results indicate that the recovery rate of the latent fingermarks on various paper items is in the range of 70–80% without chemical treatments, and such a method as UV‐excited UV fluorescence in detecting latent fingermark may be better for examination in cases where biological information of samples is needed for consequent testing.
