| Abstract: | Objective To establish high voltage electrostatic method for development of fingerprints on metal surface. Methods The fingerprints on brass, iron, aluminum and stainless steel were developed with high voltage electrostatic method after they were left 1 day, 3 days, 7 days and 15 days. The results of the magnetic powder method and the high voltage electrostatic method were compared. Results The high voltage electrostatic method is more effective than the magnetic powder method. Conclusion High voltage electrostatic method is simple and effective for development of fingerprints on metal surface. |
