成果简介	NOVELTY - Multi-doped nanostructure for latent fingerprint detection, comprises zinc sulfide as a base obtained from precursor of 220 mg zinc acetate tetrahydrate and 250 mg of sodium sulfide nonahydrate; manganese as a co-dopant obtained from 25 mg manganese(II) chloride tetrahydrate; and copper as a dopant as a dopant obtained from 25 mg of copper(II) nitrate dihydrate. The nanostructures emit fluorescence at a wavelength of 250-650 nm, depending on the doping concentration and excitation source. The nano structure is prepared by dissolving zinc, sulfur, manganese and copper precursors in ethanol to form dissolved solutions, mixing the dissolved solutions at optimum conditions to form a mixture, centrifugating the mixture to form precipitate, and drying and purifying the precipitate. USE - The multi-doped nanostructure is useful for latent fingerprint detection and in criminal investigation, authority control, and medical diagnosis. ADVANTAGE - The multi-doped nanostructure: offers significant potential for advancing forensic analysis and ultimately enhancing the overall forensic examination process; enhances compatibility with various imaging systems and techniques commonly employed in forensic laboratories and this versatility enhances the applicability and integration of the proposed method into existing forensic protocols, thus advancing the field of latent fingerprint analysis. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of multi-doped nanostructure for latent fingerprint detection, comprising (a) dissolving zinc, sulfur, manganese and copper precursors in ethanol to form dissolved solutions, (b) mixing the dissolved solutions at optimum conditions to form a mixture, (c) centrifugating the mixture to form a precipitate, and (d) drying and purifying the precipitate to form a multi-doped zinc sulfur nanostructure.
