主　　题：Fluorescent material Latent fingerprints Visual recognition Cyclic chalcone Montmorillonite 

摘      要：A new fluorescent fingerprint powder(DFF-MMT)was formulated by blending cyclic chalcone dye DFF with montmorillonite(MMT),which can develop latent fingerprints(LFPs)with exceptional resolution and contrast on various surfaces,including ordinary glass,tin foil,marble,LED screens,and materials with distinct colors and fluorescent *** fluorescence of DFF-MMT transforms from orange to bright yellow with LFPs,allowing for a flawless visualization of fingerprints on uneven surfaces or materials with static ***,fingerprints developed by DFF-MMT can be stored for over 21 months and conveniently *** developed LFPs by DFF-MMT still keep high quality under the influence of aquatic condition,illumination and thermal ***-MMT also exhibits benefits,such as affordability,real-time,high-resolution,high-contrast development and no damage to DNA,making it an ideal choice for sophisticated criminal investigations.
