Description

The treatment of information about complicated samples has led to the introduction of fingerprinting techniques. These techniques have been discovered to be very useful for examining the metabolites emitted under various conditions, including in vivo by living creatures and in vitro by cellular cultures. In order to correlate the content of exhaled air with both normal and abnormal states, breath analysis has produced some intriguing and encouraging results. The friction ridges and furrows that form on the pads of the fingers and thumbs to create fingerprints are distinctive designs. Although the prints from the palms, toes, and feet are equally distinctive and can be used to identify a person, this tutorial focuses on the prints from the fingers and thumbs. Some examiners classify fingerprints as patent, latent, or plastic imprints when they are discovered at crime scenes or when they are created in the lab. If the substrate is flexible enough at the printing stage, a plastic print is produced. The authors clearly outline how to choose the most efficient methods by outlining the methodology used for comparisons of the efficacy of various development processes. The text also examines the order and combination of strategies for obtaining different types of forensic evidence.
