摘要
A technique for producing an artificial biointerface involves providing a patterned microfluidic chip having: a chamber divided by a fluid-permeable fencing into a central region and two flanking channels; and at least 3 fluid paths, each of the paths extending across one of the central region and the two flanking channels. A porous packing of rigid beads is placed within the central region to define a bead bed, the beads being of a size to be retained by the fencing. A biowall can be grown on at least one segment of the fencing separating the central region from one flanking channel, the biowall formed at least in part by live cells cultured on the beads. Beads may be modified, coated or functionalized to improve cell attachment and growth, and for reporting, or dosing particles or molecules can be conveniently added to the bead bed.
