NANOPLASMONIC PAPER SUBSTRATE FOR IDENTIFICATION OF FENTANYL AND FENTANYL-RELATED COMPOUNDS

摘要

In an embodiment, a method to detect analytes, the method including contacting a sample on a substrate, where the substrate is a nanoplasmonic paper, performing surface-enhanced Raman scattering detection with paper chromatography separation on the substrate, and identifying at least one analyte in the sample. In a further embodiment, an apparatus to detect analytes, the apparatus including a vacuum pump coupled to a filtration unit operable to collect solid particles off an object and the filtration unit including a filter substrate, where the filter substrate includes nanoplasmonic paper.
