Abstract

Tapes are usually used in violent crimes and may contain important evidence. Separating adhesive side should be preceded to collect these evidence. In this study, we researched a novel dual-purpose reagent that can separate the tape without damaging and develop the fingerprints on porous surface when the tape is attached to A4 paper. As a result, the reagent of 1:2 ratio of 1,2-IND stock solution and HFE-7100 can separate without damaging the adhesive surface and develop fingerprints on separated A4 paper.
