Optical images of patterned microwell arrays with single cell entrapment.
(a,b) Photograph of as-fabricated microwell arrays in a honeycomb lattice. The diameter, depth and center-to-center spacing of microwell is 20, 27 and 40 μm, respectively. (c,d) Optical images of microwells in a honeycomb or square lattice with single cell entrapment. The scale bar in all the figures is 20 μm.
