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 …
