Cobalt-doped nanoporous carbon (Co-NPC) with dodecahedral shape was pyrolytically synthesized and applied as a sorbent and matrix for the enrichment and analysis of small molecules by surface-assisted laser desorption/ionization time-of-flight mass spectrometry (SALDI-TOF MS). Extremely low detection limits were accomplished for cetyltrimethylammonium bromide (1 fg·mL−1), and Rhodamine B (1 fg·mL−1) in water, and Malachite Green and its metabolite in fish blood and fish extracts (pg·mL−1 concentrations).
