The Mechanical Aspects of Formation and Application of PDMS Bilayers Rolled into a Cylindrical Structure

Figure 4

An optical micrograph of the centimeter-long rolled PDMS bilayer (a), which was connected to inlet and outlet tubing using small pieces of PDMS block to form a microchannel on the glass substrate (b). The aqueous solution containing rhodamine B dye was perfused into the microchannel at a volumetric flow rate of roughly 1 mL/min.
