Mussel-inspired enhancement of Fe3O4 catalysis was discovered towards a highly selective and sensitive colorimetric strategy for the magnetic separation-based evaluation of dopamine and/or levodopa in urine, in which the specific interaction of bis-catechol-containing analytes and mesoporous Fe3O4 NPs would form highly stable complexes of bis-catechol-Fe coordination.
