Using biofunctional magnetic nanoparticles to capture gram-negative bacteria at an ultra-low concentration.
After conjugation to vancomycin (Van), chemically stable and highly magnetic anisotropic FePt magnetic nanoparticles (approximately 4 nm) become water-soluble and capture E. coli at 15 cfu mL(-1).
