Delivery Substrates from Aligned Polymer Biomaterials for Tissue Repair


An aligned polymer article including substrates, wherein the substrates are not covalently bonded to the aligned collagen and a method of forming such articles wherein substrates are mixed with a polymer in solution to form a polymer-substrate mixture. The mixture is placed in an electrochemical cell and a voltage is applied to the cell generating a pH gradient, wherein the polymer aligns in the cell and migrates to the isoelectric plane of the polymer solution.
