| Abstract: | Objective To investigate the fingerprint developing effect by novel hydrophobic nano-silica.Method Developing effects were comparied between hydrophobic nano-silica powder and traditional materials including copper powder,aluminum powder and black magnetic powder for oil-sweat mixed fingerprints on non-permeable objects under natural light.Results The latent fingerprints developed by novel hydrophobic nano-silica powder displayed more details and better background contrast in the fingerprint image.Conclusion The novel hydrophobic nano-silica material is more effective in fingerprint development than traditional materials. |
| Keywords: | hydrophobic silica nano-powder oil-sweat mixed fingerprint development |
