Claim 0:
1. A microfluidic device mimicking a biological microenvironment, comprising:
a plurality of diffusion chambers including a central diffusion chamber, a first side diffusion chamber, and a second side diffusion chamber; and
a plurality of channels including a first channel and a second channel,
wherein the central diffusion chamber extends in a first direction and has a convex shape at a center portion thereof in a plan view,
the first channel is disposed between the first side diffusion chamber and the central diffusion chamber in the plan view,
the second channel is disposed between the second side diffusion chamber and the central diffusion chamber in the plan view, and
the second side diffusion chamber is disposed opposite to the first side diffusion chamber with respect to the central diffusion chamber in a second direction crossing the first direction in the plan view,
wherein a width of each of the first side diffusion chamber and the second side diffusion chamber in the second direction near the center portion of the central diffusion chamber is at least five times longer than a width of each of the first channel and the second channel in the second direction near the center portion,
wherein surfaces of the diffusion chambers and the channels are porous, and
wherein diffusion of a target element between the plurality of diffusion chambers is controlled by interrupting or generating fluid flow inside at least one of the channels.
