Measurement of methamphetamine on surfaces using surface plasmon resonance.

Field methods are needed to assess the contamination of surfaces by methamphetamine from illicit drug manufacturing. This study performed a feasibility study on the use of a surface plasmon resonance (SPR) based instrument (SensiQ Discovery) in the evaluation of surface contamination by methamphetamine. The main goal was to see if the method could be sensitive enough for field measurements.
