Figure 2

Characteristics of PDMS ParaStamp and ParaStamp chip. (a) shows the patterned adhesive by CO2 laser ablation and its representative micrograph of stamped pattern with waxy paramembrane, respectively. Scale bar, 1 mm. (b) Measurements of water-contact angle (WCA) for bare and wax-stamped glasses, respectively. The volume of each droplet is 1 μl. (c) Photographs showing the trapped droplets on ParaStamp chips before and after liquid PDMS poruing, respectively. (d) shows the fabricated PDMS ParaStamp and its representative micrograph of stamped pattern with waxy paramembrane, respectively. The pattern of ParaStamp is highlighted by red inks. Scale bar, 1 mm. (e) Micrographs show the concave microstructures of fabricated ParaStamp with different dimensions. Scale bar, 200 μm. (f) Relationship between the designed width for laser ablation and the concave width of fabricated ParaStamp. (g) The fabricated dimensions (width and height) in ParaStamp behave in a linear relationship (mean ± SD, n = 3 except n = 2 for 200 μm of designed width).
