Forensic Chemistry: The Revelation of Latent Fingerprints.

摘要: The visualization of latent fingerprints often involves the use a chemical substance that creates contrast between fingerprint residues and surface on which print was deposited. chemical-aided techniques can be divided into two main categories: those chemically react with residue adhere to by intermolecular forces. A plethora empirically effective revelation methods have been developed but chemistry is incompletely understood. This article briefly describes rationale most practiced today. material suitable for forensic course or an introductory introduce relevance in law enforcement. may also apply organic biochemistry when discussing noncovalent interactions.
