The schematic of three-dimensional tumor model based on a microfluidic system. The device contained three channels. Each was 30 μm in height. The width of the central channel was 100 μm, and the widths of outer channels were 200 μm each. The space between adjacent micro-posts was 4 μm. The dimension of the square micro-posts was 50 μm. Bacterial and tumor cells were loaded into the central channel. The outer channels were perfused with cell culture medium. The open circles represent outlets on the left and inlets on the right.
