Abstract

ABSTRACT Steel and aluminum metals have extensive uses, and on their surfaces, various non-porous surface techniques are being applied for the development of latent fingermarks. Recently, aqueous electrolytes have been reported for the development of latent fingermarks on metal surfaces. The metal surfaces were immersed in the electrolyte solution for development of latent marks but the immersion method for large and bulky fixed surfaces seems to be unrealistic. Therefore, in the current work, gel-based electrolytes have been prepared and applied to fixed or vertical surfaces. The suggested method has also been evaluated by a comparative assessment with powdering, cyanoacrylate fuming, and small particle reagent methods.

用电解液凝胶在固定铝和钢表面观察潜在手印
摘要:钢和铝具有广泛的用途,在其表面,各种无孔表面技术被应用于潜在手印的开发。最近,有报道称水电解质可在金属表面产生潜在的手印。将金属表面浸泡在电解液中以产生潜痕,但对于体积较大的固定表面,浸泡法似乎是不现实的。因此,在目前的工作中,已经制备了凝胶基电解质并将其应用于固定或垂直表面。该方法还通过与粉末、氰基丙烯酸酯熏烟和小颗粒试剂方法的比较评估进行了评价。
