Trial designs of hydrodynamic trap arrays. (a, b, c) Prototype weir-type array design. (a) Overview of microfluidic device design. (b) Close-up of the post array inside a flow cell. (c) Comparison of a few of the different trap depths and geometries used for testing the weir-trap approach. (d, e, f, g) Prototype trap-and-bypass array device designs and close-ups of channel/trap arrays. (d, e) Example symmetric designs. (f, g) Example asymmetric designs. Asymmetric designs were found to capture crystals more reliably. |
