Ambient Mass Spectrometry (AMS) has revolutionized forensic analysis by enabling rapid and direct detection of chemical compounds on complex surfaces with minimal or no sample preparation. Among AMS techniques, desorption electrospray ionization (DESI) and direct analysis in real time (DART) mass spectrometry have emerged as powerful analytical tools due to their speed, sensitivity, and versatility. This review examines the major applications of DESI and DART in forensic science, including the detection of explosives, gunshot residue, illicit drugs, inks, biological fluids, and latent fingerprints. The principles of each technique are briefly discussed, followed by a comparative analysis of their advantages, limitations, and performances in various forensic scenarios. Recent developments, practical considerations for implementation, and future perspectives are also addressed, highlighting the growing impact of DESI and DART in real-time forensic investigations and evidence processing.
