1 The extremely abundant amine groups of PAMAM-PMAA brushes and superparamagnetism of the Fe3O4 core endowed the composite nanospheres with high detection sensitivity (1 fmol muL-1), excellent selectivity (1 : 500 molar ratios of beta-casein/BSA) and high recyclability (five cycles) towards phosphopeptides. ferryl iron mitochondrial E3 ubiquitin protein ligase 1 Homo sapiens
