The importance of forensic chemistry in the detection of illicit substances in biological samples

Abstract

Introduction: The detection of illicit substances in biological samples is fundamental in the forensic field, with significant implications in criminal investigations and judicial processes. Forensic chemistry plays a crucial role in this context, providing advanced analytical techniques for the identification and quantification of these substances. Objectives: The present study aims to highlight the crucial role that forensic chemistry plays in the identification and quantification of drugs in biological samples.  The reader will be informed about the techniques and analytical tools that forensic chemistry uses to detect substances in biological samples such as blood, urine, organs, and tissue. Methodology: The qualitative research method of bibliographic review was used, which promoted interaction between the participants of the process, allowing the exchange of experiences. The review and collection of data was carried out in the Electronic Scientific Library, including the search for scientific articles in Google academic, Redalyc, PubMed and Elzevir, a reading order of the summaries and keywords was followed. In a search of 30 articles and 1 book. Result: The analysis of the importance, the updated techniques for the analysis and the biological samples to be considered were developed. Conclusions: Finally we can conclude the wide scope that forensic chemistry has in all areas of criminal investigation.General study area: Criminalistics and Forensic Sciences. Specific area of ​​study: Forensic Chemistry. Type of study: Bibliographic Review.
