The distinct imprints of various loops, whorls, and arches left by a finger when it comes into contact with a surface are known as latent fingerprints. Therefore, fingerprints are a reliable form of identification. Over 110 years have passed since the invention of this field of study, which uses fingerprint analysis to identify people, with little advancement. According to SWGFAST, a fingerprint comparison can only lead to one of the following conclusions: identification, exclusion, or inconclusive. Additionally, fingerprint samples include distinct chemical components that might be used to glean important details about the subject or subjects of interest. The extraction of data from the chemical composition of latent impressions involves numerous detection techniques now under investigation. These techniques comprise spectrometry, spectroscopy, and bio-assays/biosensors, among others. The most recent advancements in methods for chemical content-based fingerprint analysis will be covered in this review.
