Abstract
Fingerprints are crucial to human identification and represent a valuable form of physical evidence in criminal investigations. Consequently, research into the development of new materials for digital printing is constantly expanding. In this context, the use of materials derived from natural compounds has received increasing attention, mainly due to the toxicity associated with commercial powders. In this sense, interest in bixin arose, which is extracted from annatto seeds and has traditionally been used as a natural dye and has recognized medicinal applications. Still, its potential in the field of papilloscopy remains unexplored. In this study, composites were developed from extracted bixin. The extracted bixin was characterized by UV-visible spectroscopy, showing absorption peaks at 429, 453, and 481 nm. Meanwhile, standard bixin had peaks at 429, 457, and 487 nm. Thin-layer chromatography revealed bands with an Rf value of 0.4 for both extracted and standard bixin. Liquid chromatography confirmed identical retention times of 7.07 minutes for both bixins. The bixin/ZnCO₃ and bixin/kaolinite composites demonstrated effective development of natural and sebaceous latent fingerprints, allowing the visualization of sweat pores in some of the developed fingerprints. Thus, the formulated composites present an innovative and promising alternative for application in the area of papilloscopy.
