DEVELOPMENT OF NATURAL LATENT FINGERPRINT POWDER FROM DURIAN SEEDS - A GREEN AND EFFECTIVE APPROACH IN CRIME SCENE

This invention relates to a latent fingerprints powder. The currently available latent fingerprints are usually ineffective if the fingerprint left is not within the first week after placing the latent. The latent fingerprints visualization chemicals are toxic and potential health hazards. To overcome this problem it is provided that the Durian Seeds are made into a powder form for the development of cheaper and more effective latent fingerprint powder for better visualization. Seeds of Durian was rich in starch and will produce white powder. The powder will adheres to the residue deposited from the fingers onto the surface that we touch. The reason is also for the adherence of Durian seeds powder to the latent fingermarks can be assigned by the formation of hydrogen bonds between the fatty acids/glycerides of sebum and the carbonyl and hydroxyl group of the components in Durian seeds powder. The latent fingerprint powder produced from durian seeds showed better visualization. This will plays a significant role in identifying the criminals in crime scene by analysing the old fingerprints. This natural latent fingerprint powder also non-toxic, safe and easily available. This product also with reduced cost of production.
