        abstract = {Latent fingerprint examination remains a cornerstone of forensic identification, providing reliable and unique evidence linking individuals to crime scenes. Traditional fingerprint development techniques largely depend on synthetic chemical powders, which, despite their effectiveness, present concerns related to toxicity, environmental hazards, and cost. This study explores the feasibility of using natural plant-based reagents as eco-friendly alternatives for detecting latent fingerprints on non-porous surfaces such as glass, stainless steel, and tiles. Various plant materials—including drumstick leaves, bougainvillea, neem, banana bract, tulsi, amaranth, and marigold—were processed into fine powders and applied using standard dusting techniques. The developed fingerprints were evaluated based on clarity, contrast, and ridge detail visibility. Results indicated that powders derived from drumstick leaves, banana bracts, and amaranth produced superior ridge definitions across all tested surfaces, while others demonstrated moderate to low effectiveness. The findings highlight the potential of natural reagents as sustainable, non-toxic, and cost-effective alternatives in forensic science. This study contributes to the growing field of green forensics, emphasizing the importance of environmentally responsible methodologies without compromising investigative accuracy and reliability.},
