Efficacy and Efficiency of Fingerprint Powder Derived from Natural Flowers – Development and Evaluation of Sustainable Fingerprint Powders
Abstract: Fingerprints are crucial elements in forensic investigations. Latent or invisible fingerprints are commonly recovered from the scene of crime and hence require an attention for which visualization methods are needed. Conventional methods are relatively expensive, which may cause harmful threats and health hazards due to presence of chemical content. This study offers a cheap and sustainable fingerprint powder sourced from natural materials. In this study the powders were prepared from …

Latent Fingerprint Development via Green Synthesis of PbO Nanoparticles Using Helianthus (Sunflower) Extract
Abstract: Fingerprints are crucial evidence in personal identification, categorized into three types: latent (invisible), patent (visible), and plastic (three-dimensional). To make the latent prints visible, various techniques are used like the powder method, chemical method, and different light sources. In the powder method, commercially available powders are used and are effective; however, incorporating nanoparticles enhances their effectiveness. In this study, a novel fingerprint powder is prepared through green synthesis using distilled …
