摘要: The peroxidase-like activity of dissolved Fe3O4 magnetic nanoparticles (MNPs) was determined and compared with whole MNPs in this study. We detected the through catalytic reaction between TMB. Due to high ferric ions ferrous released from after dissolution, showed much better than MNPs. In addition, we used diagnosis mycoplasma pneumonia infection which as substitution horseradish peroxidase. Both modified amino groups (MNPs-NH2) polyethyleneimine (MNPs-PEI) were successfully indirect immunoassay for detection pneumoniae. And results more sensitive specific that (C) 2014 Elsevier B.V.
