Figure 1: Electrophoretic Deposition Device-Acrylic container (a) is 2.5 L in volume. This is sufficiently large to hold the deposition apparatus and the deposition solution. Metallic counter-electrodes (b, c) are suspended parallel to the substrate (d). A 10 V potential is applied between the substrate and the electrodes which drives alginate in the solution towards the substrate to forms a solid gel layer. A metallic ribbon (e) acts as a contact between the substrate and the voltage source but is not exposed to the solute. An acrylic holding device (f) immobilizes the substrate and ensured that it is flush against the contact strip.
