| titleOfInvention | Method for displaying latent fingerprints by adopting fluorescent dye-modified nano particles |
| abstract | The invention provides a method for displaying latent fingerprints by adopting fluorescent dye-modified nano particles. By the adoption of organic fluorescent dye chemical modified nano particles, fluorescence excitation of a normal light source during fingerprint displaying and multi-waveband fluorescence emission are realized; residues with doubtful fingerprints are put into a uniformly vibrated displaying agent, then unfixed dyes are washed off by clean water, and the residues are naturally dried; when the residues are observed under a long-wave ultraviolet lamp, a high-contrast fluorescence characteristic can be clearly seen. According to the method, the technical difficulties of interference, such as object light reflection, during latent fingerprint displaying, low sensitivity to powder displaying, low combination property, limited application range and the like are solved; the method is easy to operate and does not have toxic and side effects. |
