Abstract
From the late 90 s until recently, some forensic research has been dedicated to the development of analytical techniques to explore the chemical components present in fingerprints, in order to find other information besides authorship. Raman spectroscopy is a technique of nondestructive analysis of a wide variety of forensic evidence, including fingerprints, at the crime scene. In this context, the aim of this work is to explore Raman spectroscopy and the supervised methods, Partial Least Squares and Support Vector Machine for Discriminant Analysis (PLSDA and SVMDA, respectively), as means to determine sex based on fingerprints obtained from male and female donors and submitted to different conditions (dark and light). Considering a period up to seven days from the collection of the fingerprint, the results showed correct discrimination rates ranging from approximately 80–93%.
期刊介绍：
Forensic Chemistry publishes high quality manuscripts focusing on the theory, research and application of any chemical science to forensic analysis. The scope of the journal includes fundamental advancements that result in a better understanding of the evidentiary significance derived from the physical and chemical analysis of materials. The scope of Forensic Chemistry will also include the application and or development of any molecular and atomic spectrochemical technique, electrochemical techniques, sensors, surface characterization techniques, mass spectrometry, nuclear magnetic resonance, chemometrics and statistics, and separation sciences (e.g. chromatography) that provide insight into the forensic analysis of materials. Evidential topics of interest to the journal include, but are not limited to, fingerprint analysis, drug analysis, ignitable liquid residue analysis, explosives detection and analysis, the characterization and comparison of trace evidence (glass, fibers, paints and polymers, tapes, soils and other materials), ink and paper analysis, gunshot residue analysis, synthetic pathways for drugs, toxicology and the analysis and chemistry associated with the components of fingermarks. The journal is particularly interested in receiving manuscripts that report advances in the forensic interpretation of chemical evidence. Technology Readiness Level: When submitting an article to Forensic Chemistry, all authors will be asked to self-assign a Technology Readiness Level (TRL) to their article. The purpose of the TRL system is to help readers understand the level of maturity of an idea or method, to help track the evolution of readiness of a given technique or method, and to help filter published articles by the expected ease of implementation in an operation setting within a crime lab.
