Abstract
A method of system of forming a biopolymer hydrogel structure includes a mold loaded with a cation. At least a portion of the surface of the mold is exposed to a solution comprising a gellable polymer such as alginate. An electric potential is applied to the mold so that the cation therein and the gellable polymer migrate via electrophoresis toward the surface portion, thereby interacting and forming a hydrogel structure adjacent to the surface portion.
