4. Conclusion
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.
