Schematics of the two microfluidic devices used in this work. (a) A diagram of the perfusion cell chip depicts the two separate wafers employed in this work. The wafers were reversibly sealed with the aid of an in-house built compression frame. (b) A side view of the perfusion chip displays the cell chamber, which contained 50 000 differentiated adipocytes. Perfusion solution washed over the cells to sample secretions released from the cells. (c) The enzyme assay chip was capable of performing on-line mixing of three solutions and on-line detection of the enzymatic product. The layout shows the initial mixing channel connected to the incubation channel.
