The Indian Police JournalSummary: Small particle reagent technique is used to detect latent fingerprints on non-porous crime scene evidence, including those that have been accidentally or deliberately wetted. Conventional small particle reagent is formulated by suspending a finely powdered, insoluble, binary salt, usually molybdenum disulfide or titanium dioxide, in water containing a few drops of a surfactant. A commercial liquid detergent is generally used as a surfactant. In modified small particle reagent, a luminescent dye is added to the composition. In either case, the insoluble salt adheres to the fatty components of the sweat residue. The small particle reagent technique is also referred to as wet powdering. Reproduced
