a Schematic of the flow cell system for testing long-term antifouling activities of the prototype catheters. A zoom-in view shows the coil section. b Antifouling activities of the prototype catheters. The bar graph shows the CFU per unit interior lumen area. The representative images show the complete blockage (visible white substance) of static control (on day 3) and flat control (on day 5) catheters, while the prototype catheters remained clear on day 30. The coils for generating the magnetic field were removed before imaging in Fig. 6b. The catheters were incubated at 37 °C with a continuous flow of artificial urine medium at 10 mL h−1. Each condition was tested with three biological replicates (error bar = standard deviation; n = 3). Source data of Fig. 6b are provided in the Source data file.
