Abstract

The rose bengal reagent, based on the phase transfer catalysis technique, is a calcium-targeting reagent that forms an insoluble salt that does not dissolve in a neutral or basic solution. It is expected to be effective in developing a latent fingerprint in a wet sample. However, many previous studies did not observe the fluorescence of the developed fingerprints, nor were the proposed methods of producing the reagents the optimal develop conditions. The aim of this study was to investigate the optimum reagent composition of rose bengal by varying the concentration of rose bengal dye and phase transfer catalyst based on maximum emission fluorescence of rose bengal. As a result, it was confirmed that rose bengal and surfactant concentration were the most effective when 0.01M: 0.008M, respectively.
