Abstract

Efficient visualization of latent fingermarks is vital in forensic science considering variables like surface type, deposition time, and treatment method. Iodine fuming, a simple, non-destructive method, faces challenges with rapid fading of developed marks causing hindrance in documenting the developed marks. The present research introduces a novel iodine fuming procedure enhanced by a simple pre-treatment with tetra-n-butylammonium iodide (TBAI), a white powdery material, ensuring prolonged fixation of visualized marks. The method, effective across surfaces, both porous as well as non-porous stabilizes iodine fumed fingermarks via formation of tetra-n-butylammonium triiodide (TBATI), as confirmed through spectroscopic analyses with UV–Visible, Fourier-transformed infrared and Raman spectroscopy. Aged fingermarks up to 4 weeks developed on different surfaces responded positively to the method. The suggested method is non-destructive and simple to use.

稳定碘熏手印的新方法

考虑到表面类型、沉积时间和处理方法等变量，有效地可视化潜在手印在法医学中至关重要。碘熏法是一种简单、非破坏性的方法，但它面临着已形成的标记快速褪色的挑战，这对记录已形成的标记造成了阻碍。本研究介绍了一种新的碘烟熏程序，通过使用四正丁基碘化铵（TBAI）（一种白色粉末状材料）进行简单的预处理，确保长时间固定可视化标记。通过紫外可见光谱分析、傅里叶变换红外光谱和拉曼光谱，该方法通过形成四正丁基三碘化铵（TBATI）来稳定碘烟熏手印，无论多孔表面还是非多孔表面都有效。在不同表面形成的长达4周的老手印对该方法反应积极。该方法无破坏性，操作简单。
