Abstract

We propose an L-shaped microwell (L-microwell) array that relies on the elasticity of a polydimethylsiloxane (PDMS) substrate for trapping and pairing heterogeneous cells. We designed an L-microwell suitable for trapping single cell in each branch via stretching/releasing the PDMS substrate, and also performed 3D time-dependent diffusion simulations to visualize how cell secreted molecules diffuse in the L-microwell and communicate with the partner cell. We produced over 5000 cell pairs in one 2.25 cm² array with about 30 000 L-microwells. The proposed L-microwell array offers a versatile and convenient cell pairing method.
