Abstract
The present disclosure relates to a device for and a method of interfacial electrofabrication of freestanding biopolymer membranes comprising at least one anode; at least one cathode; at least one anode electrolyte; and at least one cathode electrolyte, wherein at least a portion of the at least one anode electrolyte and the at least one cathode electrolyte form an interface, wherein at least one polyelectrolyte complex membrane (PECM) forms at the interface of the at least one anode electrolyte and the at least one cathode electrolyte, wherein the at least one anode electrolyte and the at least one cathode electrolyte are separated by the PECM, wherein the at least one anode is disposed in the at least one anode electrolyte, wherein the at least one cathode is disposed in the at least one cathode electrolyte, and wherein the at least one anode and the at least one cathode are distal from the interface of the at least one anode electrolyte and the at least one cathode electrolyte.
