MNPs are widely used in biotechnology, magnetic resonance imaging, catalysis and other areas. In this
paper, we propose a simple, quick, inexpensive and efficient way to prepare amino-MNPs with sonication-assisted
process. The amino-MNPs prepared by hydrolyzing TEOS and APS were characterized by SEM, TEM and FTIR.
Conjugation of SA and amino-MNPs was also studied. The biotin bound capacity of prepared SA coated amino-MNPs
was 1.824 nmol/mg, which well meet the need of biological application.
Biotin bound capacity,
