Abstract

The current study aimed to present a simple, non-toxic, inexpensive, and easyto-use fingerprint powder extracted from nail henna leaf to identify latent fingerprints on porous and non-porous surfaces. The powder dusting technique was applied in the current study by using nail henna leaves with a particle size of 60 to 200 mesh. Moreover, the current study used 101 fingerprint samples derived on ethnicity, gender, and blood type to determine fingerprint patterns. The results of the development of nail henna powder from sizes 100 and 200 mesh revealed the clear visualization of fingerprint patterns with prominent brown contrast on non-porous surfaces. Besides, the loop fingerprint patterns reflected the highest percentage based on ethnicity, gender, and blood group.
