A Review of Analytical and Chemometric Strategies for Forensic Classification of Homemade Explosives

open access: yesAnalytical Science Advances, Volume 6, Issue 1, June 2025.
ABSTRACT Homemade explosives (HMEs), commonly used in improvised explosive devices (IEDs), present a significant forensic challenge due to their chemical variability, accessibility and adaptability. Traditional forensic methodologies often struggle with environmental contamination, complex sample matrices and the non‐specificity of precursor residues ...
