TI - Low-cost alternative approach to developing latent fingerprints using roasted gram flour (sattu powder)
AB - 
	Despite their presence at crime scenes, latent fingerprints are generally invisible to the human eye. we first ground the gram flour in a grinder after roasting the gram flour on a burner. using an ostrich hair brush, we applied the powder to various surfaces to develop fingerprints. Due to the powder’s low adherence on non-porous surfaces, it may be applied to a variety of contrasting surfaces and generates diverse effects. we first compared the results of our powder to those of previously published household-based powders, and then we evaluated the powders based on surface properties and other factors, such as treated surfaces, wet surfaces, rough surfaces, and more. Due to its non-toxic nature and low cost, this powder has the potential to be a low-cost and eco-friendly replacement in police practice for visualising latent fingerprints on a larger scale.
