Despite its broad uptake in materials science, electronics and other disciplines, SIMS is not routinely used in forensic laboratories. This is in part due to perceived complexity of the technique, the high set up cost and a lack of awareness amongst forensic practitioners. At Surrey we have explored potential applications of SIMS in forensic science, and this has led to the inclusion of SIMS as a potential technique in the Home Office Fingerprint Source book, the manual used by police officers worldwide. Since then, the Netherlands Forensic Institute (the national forensic laboratory of the Netherlands) have become one of the first forensic laboratories to buy their own SIMS instrument for use in casework.
In this presentation, we will report on the use of SIMS for revealing fingerprints on buried objects, monitoring drug use and determining the deposition order of fingerprints and inks. We will also report on a new technique, Direct Analyte Probed Nano Extraction (DAPNe), which we have used in conjunction with SIMS to confirm the identity and location of drugs in hair.
