Developing Latent Fingerprints: A Study with Sacred Ash, Vermillion, Corn Flour on Diverse Surfaces

Vasundhara M.

Abstract: This study analyzes the development of latent fingerprints using daily materials, with a focus on creating chemical - free, non - toxic, and cost - effective fingerprint powders. Commonly used fingerprint powders often contain chemicals that may be harmful or expensive, limiting their application and availability. In this gap, this study aims to develop alternative powders using readily available materials, particularly corn flour, sacred ash, and vermilion, which are non - toxic, inexpensive, and environmentally friendly. The impact of these powders will be evaluated on a range of surfaces, including door locks, tiles, granite, eyeglasses, polished wood, stainless steel, and tempered phone glass, to assess their ability to reveal latent prints under various environmental conditions. The study will examine the powders based on factors such as visibility to make sure they meet the practical requirements of fingerprint analysis in various forensic investigations. The project aims to offer a user - friendly alternative to traditional fingerprint powders by means of using daily materials. The result will help to build inexpensive, more exact, widely usable tools for forensic investigations, therefore providing a solution that is more Suitable for a wide range of investigations.
