Carbon nanotubes for immunomagnetic separation of Escherichia coli O157: H7.
Bovine serum albumin-functionalized multiple-walled carbon nanotubes with encapsulated ferromagnetic elements were conjugated with pathogen-specific antibody, and the conjugate was evaluated for immunomagnetic separation of Escherichia coli O157:H7 in pure and mixed (with Salmonella Typhimurium) cultures.
