Multi-gradient hydrogels produced layer by layer with capillary flow and crosslinking in open microchannels.

Abstract

This technical note describes a new bench-top method for producing anisotropic hydrogels composed of gradient layers of soluble factors, particles, polymer concentrations or material properties. Each gradient layer was produced by a previous gradient method in which a droplet of one precursor solution was added to a thin layer of a second solution. The… (More)
