The aim of this study was to evaluate the possibility of developing fingerprints with uniquely formulated composition A on surfaces submerged in water. It can, therefore, be concluded that this aim has been achieved, showing that, even under wet and moist conditions, it is possible to develop finger marks and that infallible evidence such as fingerprints should not be overlooked on physical evidences found in drainage water, pool, river etc. The results showed that the most effective method for developing finger marks on non-porous surfaces exposed to water is SPR.30 The new SPR composition proved to give better results when compared with results given by formulation B. The raw materials used for preparing the present small particle reagent are cost-effective and easily available. These pose no occupational hazard to the user.
