Development of Latent Fingerprint by Corn Seed Powder

One of the earliest techniques in forensic science is the development of fingerprints, which is a popular technique for identifying criminals. Due to their ease of use and effectiveness, the powder and ninhydrin methods remain the most popular ones in forensic investigation. Latent fingerprint detection is frequently done using powder dusting. In order to replace expensive, toxic, and complex powders, we need to find a cheap, non-toxic, widely accessible powder. For the visualisation of latent finger prints, we use corn seed powder in this method. Determining the most affordable and accessible household powder used in Indian homes for the purpose of developing fingerprints. The majority of rigide cases showed clear ridge detail on different surfaces in the results, as opposed to rigides developed using non-conventional powder. This paper describes the use of a non-conventional powder for the visualisation of latent fingerprints on porous, semi-porous, and non-porous surfaces.
