The placenta‐on‐a‐chip consists of two layers of PDMS separated with a porous membrane and channel on each side. a) Top and bottom layers with a porous membrane separating the channels before being attached. b) Channels aligned and ready to be attached and the porous membrane placed in between the layers to separate the midsections of each channel (where two cell layers interact). c) Cross‐sectional view of the channels. d) Experimental concept that shows the maternal and fetal bloodstreams perfused through the channels (not to scale).
