Main Article Content
Abstract
Impressões digitais latentes coletadas em cenas de crime são vestígios frequentes e relevantes às investigações policiais, entretanto ainda se observa baixas taxas de sucesso quanto à qualidade de sua revelação com as técnicas convencionais, especialmente no caso de superfícies metálicas. Nesse contexto, o trabalho apresenta uma estratégia de revelação de impressões digitais latentes através da eletrodeposição de polímeros condutores em superfícies metálicas, que se mostra como uma metodologia promissora para a Química Forense. Os resultados apresentaram detalhes completos das cristas papilares e impressões digitais totalmente identificáveis, mostrando se tratar de uma metodologia simples, eficiente, barata e de baixa toxicidade.
