Özet
Aqueous electrolytes have recently been introduced as a new chemical technique for development of latent fingermarks on various sur- faces. The electrolyte solution was prepared based on the electronegativity series of the elements. The application methods such as immersion, spray, drop and gel (based) methods were applied, and the latent fingermarks were found to develop in few minutes and were permanent in nature on metal surfaces. The study was further extended to develop an aqueous electrolyte reagent (AER) which could develop latent fingermarks on different types of porous, semi-porous and non-porous surfaces. The surface independency and permanent nature of the developed fingermarks were the main advan- tages of this technique.
