a ELISA of MNPs@Ab confirmed the antibody conjugation. The data are presented as the mean ± sd (n = 3). b TEM image of MNPs@Ab and size distribution of MNPs@Ab (inset). c Magnetic hysteresis loops of MNPs@Ab and MNPs. d, e Optical microscopy d and TEM images e of the food vacuoles in natural Para. The highlighted vacuole area was enlarged. f, g Optical microscopy f and TEM images g of the food vacuoles of E-Para. The highlighted VSO area was enlarged. h Magnetic hysteresis loops for natural Para and E-Para. i For fabrication of E-Para, Para were cocultured with different concentrations of MNPs@Ab for 2 h. The obtained E-Para were then cultured in medium without feeding for another 24 h for toxicity evaluation. The data are presented as the mean ± sd (n = 3). j Speeds of natural Para and E-Para. The data are presented as the mean ± sd (n = 3). In i, j, statistical significance was calculated via two-tailed Student’s t test. P < 0.05 was considered significant. Ns not significant.
