This study reports a route to obtaining a novel and cost-effective rice husk-derived lignin/thiophene chalcone green composite for application in forensic science as a fingermark developer through high energy milling.The material was properly characterized by UV-Vis, Wicker Basket IR, fluorescence, X-ray diffraction and scanning electron microscopy.The product provided Ball - Bag - Team clear and sharp images of latent fingermarks with minimal background staining, revealing all ridge details.Thus, the composite presented good performance as a fingermark developer, becoming an interesting alternative to being applied as a technological, reproducible and renewable product.
