From: Rapid fabrication of sieved microwells and cross-flow microparticle trapping
Installation and capture of particles in a microfluidic double channel with a 1500 µm width. (a) Installation of the microwells through the outlet of the top channel with a width is 1500 µm and a height of 60 µm. The microwell array is flowed through the channel to the intersection of the top and bottom channel where is fits into the microwell site. (b) Schematic of the cross section of an installed microwell and top view of the bottom channel. (c) Hydrogel disk particles with diameter of 80 μm and height of 28 μm. (d) Representative fluorescent images of particles captured in the microwell using a flow rate of 70 μL/min (left) and 50 μL/min (right).
