The field of forensic science necessitates the utilization of efficient techniques for the enhancement of latent fingerprints. Environmental issues are frequently raised when traditional approaches are employed in this context. This study introduces an innovative and ecologically responsible solution to this challenge in the form of Alternanthera Dentata (AD) leaf powder. AD is renowned for its striking and vivid deep purple leaves, and it unveils remarkable properties as a natural pH indicator. Its distinctive characteristic lies in the ability to undergo a vivid transformation from a rich crimson hue to a greenish-yellow tint, responding to alterations in pH levels, a phenomenon attributed to its anthocyanin content. The research demonstrates the versatility of AD leaf powder across diverse surfaces and its distinctive ability to indicate pH levels. The use of methanol for AD leaf powder extraction enhances the sensitivity of anthocyanins to pH fluctuations. The innovative approach not only proves the efficacy of AD leaf powder in enhancing fingerprint clarity but also emphasizes its eco-friendliness and cost-effectiveness. This study establishes Alternanthera Dentata (AD) leaf powder as a promising and sustainable solution for latent fingerprint enhancement in forensic science. The compatibility of AD with various surfaces, coupled with its natural pH indicator properties, positions it as a valuable resource. The incorporation of methanol further boosts sensitivity, highlighting the eco-friendly and cost-effective nature of this innovation. By embracing environmental sustainability principles, this research contributes to a greener and more responsible future for forensic science applications.

Since waste materials are used to identify, individualize, and evaluate evidence like fingerprints, palmprints, footprints, etc. that are found at a crime scene, they have a substantial impact on the field of forensic science. Many waste powders have recently been employed in fingerprint recognition. Nanosheets made up of eggshells have been put forward as an application in friction ridge development. Eggshell is a biochemical substance made up of chemical compounds like calcium carbonate, which is considered as a waste product. For the formation of an eggshell nanosheet (ESN), shells are dried and crushed into a fine powder and to get this powder in the form of a nanosheet, the Ball milling technique is used. The synthesis of pure ESN is confirmed by Scanning Electron Microscopy (SEM) and X‐ray diffraction (XRD) techniques. The size of nanosheets ranged from 30 to 90 nm as shown in SEM images. Developed powder is then used for the application of fingerprint development and it provides excellent results on all porous, non‐porous, and semi‐porous surfaces. Thus, this newly synthesized ESN powder can be used as a significant powder method in latent fingerprint technology.

“…The powder method starts with the application of fine fingerprint development powder or mixture (abebe, Murthy, amare Zereffa, Dessie, 2020; aseri et al, 2022; Bumbrah, 2017). The fingerprint development powder adhere mechanically to the secretions of the various glands on the fingerprint and fingerprint marks, then the excessive powder should be removed (Han et al, 2004;Lohar et al, 2022;Shah, 2013). The size and shape of the powder particle plays an important role in determining the adhering capacity of powder.…”

Fingerprints are the friction ridges found on the fingers and palm of hands. These prints are considered the most valuable evidence in the court of law as these ridges provide uniqueness to every individual. Powder dusting is one of the prevalent approaches to developing fingerprints on various surfaces. This involves the application of finely formulated powders on the fingermark impression using a camel hair brush. in this article, we have used organic household waste materials like rose and hibiscus petals for developing the powders used in latent fingerprints development. The particle of powder gets adhered to sweat and moisture deposited on the surface of fingers, palm, and sole, which provide effective visualization and give the fingerprint details (minutiae). Finally, the formulation of the powder sticks to the ridges, and the excess powder is blown away. The powder is multicolored in this case, the patterns are apparent, resulting in an exceptional outcome. The objective of the study is to provide a replacement to the conventional, expensive and toxic laboratory powders. These organic powders are easily available, eco-friendly, cost-effective and non-toxic approach for latent fingerprint development and is a reliable technique to use at crime scene and future use.
