Low-cost Portable Raman Instrument, a Tool toward Counterfeit Medication Identification

: We have successfully built a low-cost (under 500 CHF) portable Raman spectrometer based on scavenged, consumer electronics. The instrument prototype is designed as a tool to help identify counterfeit medication in low-income countries. As a proof of concept, we confirmed the presence of acetaminophen, a type of analgesic, in over-the-counter drugs from around the world.
