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 particularlyExpand
TV system for detection of latent fingerprints
A fingerprint is reliable evidence for recognizing criminals in detecting cases. There are many conventional chemical and physical methods in detecting fingerprints. In this paper, a newly developedExpand

Inherent Fluorescence Detection of Latent Fingermarks by Homemade Shortwave Ultraviolet Laser
TLDR
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.

Portable hyperspectral imager with continuous wave green laser for identification and detection of untreated latent fingerprints on walls.
TLDR
The present results demonstrate that a combination of a portable HSI and CW green laser has considerable potential for the identification and detection of untreated latent fingerprints/palm prints on the walls under study, while the use of HSD makes it practically possible for doubly overlapped fingerprints/Palm prints to be separated spectrally.
