APLICAÇÃO DE CONDIMENTOS NA REVELAÇÃO DE IMPRESSÕES DIGITAIS LATENTES: UM EXPERIMENTO NO ENSINO DE QUÍMICA

The development of fingermarks is an important step in criminal cases. Latent fingermarks require applications of reagents to be developed before they can be visualized. Different techniques to enhance fingermarks’ visualization have been employed and the powder dusting is the most common among them. The use of food spices as latent fingermarks developers could be an alternative method of experiment in chemistry teaching, considering that they are low cost and accessible. In this work, an experimental methodology was developed and can be applied in undergraduate chemistry teaching for the ex...
