Journal Title: International Journal of Forensic Sciences - Year 2018, Vol 3, Issue 1
Abstract
There are several procedures available for the development of invisible fingerprints on different surfaces. This Research Study presents a Rock Phosphate powder are use which is simple for the development of Invisible fingerprints on Porous or nonporous surfaces. Fingerprints get developed on ten different surfaces such as Paper, Plywood, Plastic sheet, Granite Marble, Iron, wood, utensils. The fine dust of Rock Phosphate Powder gets attached with the fatty acid present in the sweat of a fingerprint and invisible fingerprint pattern can be clearly observed on the surface. Research studies shows that it gives good results on most of the surfaces with clear fingerprints pattern and ridges.
