MALDI-TOF-MS spectra of permethylated glycans desalted directly on MALDI plate, using CNPs@Fe3O4 NCs, spotting the equivalent of glycans derived from (a) a mixture containing 100ng of RNase B, 200 ng of fetuin, and 500 ng of AGP (b) 0.5μl of human blood serum. The total amount of sample prepared is detailed in the Experimental section. Symbols as in Fig. 2.
