摘要
Abstract: This review provides a comprehensive examination of the application of fluorescence materials for the detection of latent fingerprints in forensic sciences. Traditional methods like powder dusting, cyanoacrylate fuming, chemical methods, and small particle reagent techniques have shown limitations due to issues like low contrast, sensitivity, selectivity, and high toxicity. To overcome these drawbacks, recent focus has shifted towards using fluorescent materials, owing to their unique optical and chemical properties. This review underscores the importance of latent fingerprint development employing metal nanoparticles, semiconductor nanoparticles, and organic fluorescence compounds. These advanced materials not only provide heightened contrast, sensitivity, and selectivity compared to traditional methods but also manifest diminished toxicity. In essence, the review delivers a methodical survey of these pioneering techniques.
