Resumo: | Fingerprints are unique for each individual contributing to human identification in forensic cases. Visualization of latent fingerprints usually involves the use of a chemical substance that creates a contrast between fingerprint residues and the surface on which the print was deposited. Commercial powders used as fingerprint developers by papilloscopy have relatively high costs due to their importation and chemical composition. (E-1,3-diphenylprop-2-en-1-one, E-1-phenyl-3-(4-methylphenyl))prop-2-en-1-one but only one compound was highlighted, E-3-(3-nitrophenyl)-1-phenylprop-2-em-1-one). The composite was selected for its suitable properties (adhesion and texture) of visualization of the digital, providing the obtaining of clear revelations with identification of minutiae and singular points of the fingerprints. Identification, magnetic resonance, granulometry and contact surface evaluation with chalcones such as sebaceous and natural deposition with development in different materials such as plastic, metal and glass were applied for the application of fingerprint development. The compound was tested in eight volunteers regardless of gender and age, presenting satisfactory results for fingerprint development on glass and metal surfaces. |

Fingerprints are unique for each individual contributing to human identification in forensic cases. Visualization of latent fingerprints usually involves the use of a chemical substance that creates a contrast between fingerprint residues and the surface on which the print was deposited. Commercial powders used as fingerprint developers by papilloscopy have relatively high costs due to their importation and chemical composition.

The composite was selected for its suitable properties (adhesion and texture) of visualization of the digital, providing the obtaining of clear revelations with identification of minutiae and singular points of the fingerprints. Identification, magnetic resonance, granulometry and contact surface evaluation with chalcones such as sebaceous and natural deposition with development in different materials such as plastic, metal and glass were applied for the application of fingerprint development.
