Síntese de nanopartículas de prata, através do extrato de jambu (Acmella oleracea (l.) R.K. Jansen e Acmella ciliata (Kunth) Cass.) como possível agente revelador de impressões digitais latentes (IDLS)

Abstract

From the advancements in the 20th century, due to the implementation of Automated Fingerprint Identification Systems ( and the development of novel reagents for the treatment and revelation of latent fingerprints ( new accessible possibilities emerged for researchers from diverse fields of knowledge. A new direction for the t reatment and analysis of IDLs presented itself, such as the utilization of nanotechnology. Generally, their fabrication occurs through physical or chemical methods involving noble metals; however, many of these methods entail expensive equipment, multiple steps, and generate toxic byproducts. This is why green synthesis has been studied and sought after by numerous researchers, as it offers rapid, cost effective production that is environmentally benign. Within this context, the objective of this work was t o characterize and assess the effect of silver nanoparticles produced from plant extracts of two species known as Jambu Acmella oleracea ( R.K.Jansen and Acmella ciliata ( Cass typical plants of the Pará region, to determine their potential as la tent fingerprint revealing agents ( Thus, the aim was to develop an effective IDLs revealing agent, with costs relatively lower than current options and environmentally innocuous, utilizing extracts from Acmella oleracea ( R.K.Jansen and Acmella c iliata Kunth) Cass typical plants of the Pará region.
