A porous polymer coating transfer enrichment method is developed for the direct mass spectrometry (MS) analysis of lipids. The enrichment is fast (ca. 1 min) and enables the profiling and quantitation of lipids in small-volume biofluid samples. Coupled with a photochemical Paternò-Büchi reaction, this method enables the fast determination of lipid structure at the C=C location level and point-of-care lipid biomarker analysis.
