Current techniques for visualization of latent fingerprints include cyanoacrylate fuming, luminol testing, and powder dusting. Drawbacks to these methods include a short fluorescent period and oversaturation of the fingerprints. This project involved the synthesis and characterization of Mn-doped ZnS quantum dots for potential use in fingerprint analysis. Quantum dots have highly fluorescent properties that make them useful for visualization. Due to their small size, the quantum dots can adhere to the fingerprints and make them visible under UV light. This technique proved promising due to the stable, long-lived images of the fingerprints.<br/>
