Abstract: The most common techniques for finding the latentprints is powder dusting, which contains chemicals that could be harmful to the environment and human health. so Investigating the natural and environmentally suitable substitutes is necessary as sustainability gains more attention. In this Sweet potatoes (Ipomoea batatas) are the starchy root vegetables, It is a well-liked food crop all around the world because of its many health advantages and sweet, nutty flavour. A biodegradable and renewable substance, sweet potato powder is made from dried and crushed sweet potatoes and may find application in forensic science. Sweet potato powder is a new and creative technique for latent fingerprint detection that offers a healthy and environmentally friendly substitute for conventional techniques. It is a good option for latent fingerprint visualisation because of its delicate texture and organic pigments. The current work suggests a novel, easy-to-use powder approach that is inexpensive, safe for human health, and suitable for developing latent fingerprints on a variety of nonporous surfaces. In this investigation, a feather brush is used to identify latent fingerprints on a variety of surfaces, including glass, metal, and plastic. The purpose of this study is to employ sweet potato powder to create latent fingerprints on nonporous surfaces and to evaluate the powder's efficacy on different nonporous surfaces that contain latent fingerprints using a grading system. The development of latent fingerprints on different surfaces has been explained by a variety of powder techniques, however some of these techniques can be costly and may cause health issues if they are used on people. Latent fingerprints can be developed at the crime scene using this straightforward and simple approach.
