Figure 2.
(A) The results for magnetic separation of Salmonella Typhimurium (1 mL, 103 CFU/mL) by the immune MNPs (50 μL, 2 mg/mL) with different incubation time from 15 to 60 min. The optimal incubation time is selected as 45 min. (B) The results for magnetic separation of Salmonella typhimurium (1 mL, 103 CFU/mL) by the immune MNPs (50 μL, 2 mg/mL) using 3 different strategies (both capture and separation in tube, capture in tube and separation in capillary, and both capture and separation in capillary). The most suitable strategy is capture in tube and separation in capillary after trading off the separation efficiency and operation skills
