摘要：

The powder technique for detecting latent fingerprints involves the application of a finely divided formulation to the fingermark impression. generally with a glass-fibre or a camel hair brush. The powder gets mechanically adhered to the sweat residue defining the ridge pattern. The furrows which are devoid of the fingerprint residue, do not adhere the powder onto them. The final outcome is that the powder formulation sticks to the ridges, but is easily blown off the furrows. Since the powder is normally coloured, the ridge pattern becomes visible and the latent print is said to have developed. (C) 2001 Elsevier Science Ireland Ltd. All rights reserved.
