| Abstract: | Objective To evaluate the effects of particle size of nano zinc oxide for latent fingerprints development. Method Fingerprints developed by four different size nano zinc oxide were compared under UV light and white light. Result Fingerprints developed by different sizes powders were different under two kinds of light. Conclusion In consideration of the type of the fingerprints and the color of backgrounds, we should chose proper size of nano zinc oxide. |
