A New Technique For Visualization Of Latent Fingerprints On Different Surfaces Like Kitchen Appliances And Plastics Using Aalampattai Powder

Abstract

AIM-Aim of the study is to find out the new techniques for visualization of latent fingerprints on different surfaces using Aalampattai powder (Ficus bengalensis)

Introduction- ​A fingerprint is an impression left by a human finger's friction ridges. An important method of forensic science is the retrieval of partial fingerprints from a crime scene. On different surfaces such as glass or metal, moisture and grease on a finger result in fingerprints.

Materials and methods- Novel products are used in this research. This research should be continued on trails. The sample is taken in powder form. Based on the previous research work articles will be collected and the work be carried out accordingly. Aalampattai stems were collected and dried for 7 days. After that it was kept in the shade dry for 3 days. Then it is made into powder form. Then using the powder fingerprint dusting is done.

 Results and Discussion-The method we used to detect fingerprints is called dusting, the powder which we used is aalam pattai powder.This powder sticks to the oil in the fingerprint, and makes it visible. Once the fingerprint becomes visible, we are able to lift it from the surface with a tape and transfer it to another surface. then it can be taken to the laboratory to analyse further.

Conclusion-The aalam pattai powder (Ficus Bengalensis), we can get visible fingerprints and also we can make fingerprints using the powder. . Further tests and studies have to be done to make it an effective potent powder that is dusting powder readily and cheaply accessible for fingerprints.
