The fingerprints were developed on the aluminum foil warp and white office paper by first swabbing the fingers on the sebum rich surfaces on the human face like nose and forehead, then gently press the respective fingers on the surfaces to have nice and undisturbed fingerprints. By following the powder dusting method, the dry strongly yellow, fluorescent powder of PTE-II was lightly spread over the fingerprints impressed surfaces and left for 5-10 minutes, then cautiously excess of the powder was removed by using very fine paint brush. The fingerprints with adsorbed powder on different surfaces visualized under both daylight by using naked eyes and under an illumination of 365 nm UV lamp. Perylene 3, 4, 9, 10-
