From: Using Positively Charged Magnetic Nanoparticles to Capture Bacteria at Ultralow Concentration

Fig. 7

Capture efficiencies of E. coli by NP+ or NP− at ultralow concentrations. The left image is the photograph of LB-agar plates coated with E. coli captured by NP+ and NP−. The right image showed the E. coli capture efficiency of NPs (40 μg/mL) with ultralow concentrations of bacteria. E. coli (10 and 100 CFU in 1 mL PBS solution) without NP incubation was counted as 100% and served as control. ***P < 0.001
