In this paper, we describe a novel method for detecting Escherichia coli (E. coli) O157:H7 by using a quartz crystal microbalance (QCM) immunosensor based on beacon immunomagnetic nanoparticles (BIMPs), streptavidin–gold, and growth solution. E. coli O157-BIMPs were magnetic nanoparticles loaded with polyclonal anti-E. coli O157:H7 antibody (target antibody, T-Ab) and biotin-IgG (beacon antibody, ...
