Green Synthesis of Eco-Friendly Fingerprint Powders from Brewed Green and Black Tea Leaves

The present study entitled “Green Synthesis of Eco-Friendly Fingerprint Powders from Brewed Green and Black Tea Leaves” was conducted in the department of Forensic Science, JECRC University, Jaipur. The objective of the study was to formulate a sustainable and greener fingerprint powder using brewed green and black tea leaves and to check the efficiency on various porous and non-porous surfaces. Samples of green tea and black tea were collected, cleaned, dried, grounded, sieved and stored. These powders were applied on various porous and non-porous surfaces and the developed latent fingerprints were photographed. The ridges were clearly visible even with the minute details making them suitable for comparing and analysing. A clarity score was denoted to each developed fingerprint using the standardized grading scale. Statistical test was applied to check whether the powders have equal efficiency with porous and non-porous surfaces. The purpose of this research is to investigate the feasibility and effectiveness of using these powders in forensic investigations, as well as to emphasize their contributions to sustainable and ecologically conscientious crime scene analysis. This research opens doors for further exploration of unconventional, safe, and affordable fingerprint powder.
