Bioinspired fabrication of bifunctional antibody–enzyme co-assembled nanocomposites for chemiluminescence immunoassays of E. coli O157:H7

Herein, antibody–HRP co-assembled nanocomposites with enhanced stability were successfully fabricated and employed as an alternative to traditional enzyme-labeled antibodies to develop a chemiluminescence enzyme immunoassay toward E. coli O157:H7.
