Monofunctional curcumin analogues: evaluation of green and safe developers of latent fingerprints

Characterization of Bixin by UV-Visible Spectroscopy and HPLC, and Its Application as Latent Fingermark Developer

“…For preliminary tests, glass slides were used to deposit fingerprints from four random donors. The method by Pacheco et al (2021), was used for the deposition of natural and sebaceous fingerprints. To simulate a natural fingerprint deposition, participants washed their hands using neutral soap and water, subsequently engaging in their routine activities for 30 min.…”

“…To simulate a natural fingerprint deposition, participants washed their hands using neutral soap and water, subsequently engaging in their routine activities for 30 min. For a sebaceous deposition, the donor rubbed their thumb on facial areas, including the forehead and nose, followed by fingertip rubbing to enhance the print with oily components, due to the lack of sebaceous glands on hands [39]. During the fingerprint placement, the pressure applied was subjectively firm (exerting medium pressure), contact time was between 3 and 5 s, and fingerprints were revealed using commercial and composite powders after 24 h. For comparison, the same fingerprint was deposited on two glass surfaces, with the left half of the fingerprint revealed using the prepared composites and the right half using the White ® fingerprint powder acquired from Sirchie (Youngsville, LA, USA).…”
