Phone-Based Raman Spectrometer Recognizes Materials in Minutes
COLLEGE STATION, Texas, July 29, 2024 — Scientists, medical personnel, and others will be able to quickly identify drugs, chemicals, and biological molecules with a handheld device for Raman spectrometry invented by a team at Texas A&M University. The portable Raman spectrometer is suitable for use in remote settings where laboratory-based spectrometers are impractical due to their large size, cost, and power demands. The Raman spectrometry system integrates lenses, a diode laser, and diffraction and transmission gratings
