Natural Methods for the Identification of Fingerprint by Using Sandal Wood Powder

Abstract

Different methods have been suggested for the development of latent fingerprints on different surfaces. Fingerprint are an important kind of material evidence with the key function in personal identification. Fingerprint are unique and lifelong to everyone. This paper presents a new natural powdering method which is simple and non-toxic for the development of latent fingerprint. In investigation a less expensive, simple and easily available sandal wood powder. A commonly found in Indian trees/plants. It is found that it gives very clear result in majority of the surfaces. This powder developed fingerprints on different surfaces like metal surfaces, clay surfaces, non-porous surfaces, and computer/ mobile surfaces. It shows clarity of ridges. It successfully developed latent fingerprint on all the surfaces except skin and cotton by using this method. In this method using AgNo3 Nano synthesis particles by using extraction process of the sandal wood powder. We have to done successfully developed latent fingerprint powder.
