Summary
Solid-phase microextraction (SPME) offers a versatile, solventless forensic analysis method. This review highlights its application in drug identification, fatality investigations, and alcohol abuse markers, demonstrating its effectiveness across various forensic contexts.
Area of Science:
- Forensic Science
- Analytical Chemistry
- Toxicology
Background:
- Solid-phase microextraction (SPME) has been a key advancement in forensic science since 1990.
- It provides a fast, solventless alternative to traditional extraction methods, enhancing forensic analysis versatility.
Purpose of the Study:
- To systematically review the applications of SPME in forensic science between January 1995 and June 2018.
- To consolidate findings on SPME's utility in diverse forensic investigations.
Main Methods:
- Systematic literature review adhering to established guidelines.
- Analysis of 133 articles focusing on SPME applications in drug identification, fatality investigations, alcohol abuse markers, human odor profiling, and living individuals.
Main Results:
- SPME is widely used for drug identification (40/133 articles) and investigating fatalities (29/133 articles).
- Headspace SPME is preferred for detecting alcohol abuse markers (28/133 articles) and analyzing volatile organic compounds for odor profiling.
- Polydimethylsiloxane fibers and Gas Chromatography/Mass Spectrometry (GC/MS) coupling are frequently employed.
Conclusions:
- SPME demonstrates significant success in analyzing both living and cadaveric biological samples.
- SPME findings, particularly for alcohol biomarkers in hair, are adopted by professional societies for abstinence verification and chronic alcohol consumption assessment.

Sample Preparation for Analysis: Overview
2.2K
Sample preparation is an essential step in the analytical process. It involves preparing a sample so that it can be analyzed accurately. The goal is to extract the analyte, the substance you want to measure, from the sample while removing any components that may interfere with the analysis. Sample preparation techniques vary depending on the physical state of the sample.

DNA Isolation
44.3K
DNA isolation protocols can be fast and straightforward or complex and time-consuming depending on the type and quality of DNA required for further processing. For example, plasmid DNA extraction is a bit more complicated than genomic DNA extraction because of the need for an appropriate lysis method to separate plasmid DNA from gDNA during isolation. However, for specific applications, such as long-range DNA sequencing that require a good yield of high- quality DNA samples, we need to follow...
