Abstract

Aim and objective: The current study aims to explore the effectiveness of food dyes as potential agents for the formation of latent fingerprints on non-porous substrates.


Introduction: The development of fingerprints is a long-established forensic technique crucial for identifying perpetrators. Traditional methods often use various powders to reveal latent fingerprints on different surfaces, but these methods can be costly and pose health risks when exposed to humans. Consequently, there is an increasing demand for alternative techniques that are cost-effective while still providing high-resolution fingerprint visibility.


Materials and methods: In this study, Colormist Super whip food powder red, blue, orange, turquoise, and pink was used for the Development of Latent fingerprints on different non-porous surfaces (CD, Mobile screen, Glass bottle, Mirror, Steel bottle).


Results: The ColorMist Super Whip edible powders proved successful in developing high-quality finger marks with visible level 1 and level 2 fingerprint details across all substrates, showcasing its effectiveness in latent fingerprint enhancement.


Conclusion: Food dyes provide a simple, cost-effective, and eco-friendly method for developing latent fingerprints on nonporous surfaces. Red and black dyes consistently deliver clear ridge detail, while turquoise performs well on glass. Surface type plays a crucial role in dye effectiveness; making food dyes a practical, non-invasive alternative for on-site forensic use.
