Claim Text:
1. A microfluidic device comprising: a substrate comprised of an optically transparent material and further comprising i) one or more fluid channels; ii) one or more fluid channel inlets; iii) one or more fluid channel outlets; iv) one or more gel cage regions; and v) a plurality of posts; wherein all or a portion of each gel cage region is flanked by all or a portion of one or more fluid channels, thereby creating one or more gel cage region-fluid channel interface regions; and each gel cage region comprises at least one row of posts which forms the gel cage region, each post of the at least one row of posts forming a triangular shape, a trapezoidal shape or a combination thereof, the sum of a contact angle of a gel on a surface of the substrate and an internal angle of a corner of each post of the at least one row of posts being about 180°, and a distance between each neighboring pair of posts in the at least one row of posts being from about 50 micrometers to about 300 micrometers.
