Fingerprints,as stable and unique lifelong biological identifiers for individuals,play an irreplaceable role in criminal investigation and identity verification.Traditional latent fingerprint visualization techniques,however,often suffer from low sensitivity,poor contrast,and the risk of trace damage when dealing with complex objects,background interference,and aged fingerprints.Therefore,there is an urgent need for new and efficient visualization systems.Nanoluminescent materials,with their high specific surface area,controllable optical properties,and easy functionalization,can achieve fluorescence imaging through specific interactions with fingerprint residues,providing a new path for high-resolution and high-contrast visualization of latent fingerprints.This paper systematically reviewed the research progress of quantum dots,carbon dots,metal-organic frameworks,and rare earth nanomaterials in latent fingerprint visualization.It focused on analyzing the luminescent properties of various materials,visualization strategies,and interaction mechanisms with fingerprint residues,and compared the differences in visualization accuracy,background suppression ability,and applicable scenarios among different systems.Based on existing research results,it analyzed the key issues in material synthesis,practical application,and operational stability,and looked forward to future development directions such as green synthesis,multi-modal luminescence,intelligent recognition,and on-site adaptability,providing a reference for the basic research and practical application of nanoluminescent materials in latent fingerprint visualization.
