The Diatom Nano-fingerprint powder, developed collaboratively by researchers from the Department of Criminology and Forensic Sciences at Dr Hari Singh Gaur Central University, promises to revolutionize forensic investigations with its eco-friendly, cost-effective and highly efficient properties. Led by Dr Vandana Vinayak, Assistant Professor from Sagar, the project has achieved a significant milestone with the grant of a patent for this innovative powder, marking the culmination of nearly a decade of dedicated research on algae diatoms.
Dr. Vandana Vinayak emphasized the critical role of fingerprints in forensic investigations and highlighted the environmental and health hazards posed by the chemical-based fingerprint powders currently in use. The newly developed diatomite powder, on the other hand, offers a safer, non-toxic alternative that effectively lifts fingerprints from various surfaces without compromising their integrity. The successful invention of this powder owes much to the contributions of research students Ankesh Ahirwar, Vandana Sirothia, Priyanka Khandelwal, Gurpreet Singh and Urvashi Soni.
Despite the university administration’s announcement on Monday, the patent acquisition from Germany on January 26 underscores the international recognition of the powder’s significance. Dr Vandana Vinayak elucidated the powder’s preparation process, involving the reaction of fluorescent dye, diatom frustules (diatomite) and a polylinker in the department’s diatom lab. Through chemical interactions with perspiration, the powder adheres to surfaces, allowing for the capture of high-quality fingerprint photos using fluorescence photography.
The commendation from Prof. Neelima Gupta, Vice Chancellor of the university, underscores the recognition of Dr. Vandana and her team’s commendable achievement. The Diatom Research Unit, part of the university’s Department of Criminology and Forensic Sciences, has further solidified its reputation with the grant of an International Patent from Germany, a testament to their collaborative efforts under the Indo-French Project (CEFIPRA). This patent pertains specifically to the synthesis of diatom nano-fingerprint powder containing fluorescence dye, marking a significant milestone in the field of forensic science.
The development and patenting of the Diatom Nano-fingerprint powder represent a significant advancement in forensic technology, promising to enhance the efficiency and sustainability of forensic investigations worldwide.
