3. Our ECD: layer by layer

4. Contrast determined by Coverage of phage by IrOx

5. Contrast determined by Coverage of phage by IrOx Uniformity of phage deposition 100  m images from Yoon Sung Nam

6. Contrast determined by Coverage of phage by IrOx Uniformity of phage deposition Adhesion of phage*IrOx particles to electrode Transparency of electrode, electrolyte, other materials

7. Switch speed determined by Concentration of Li+ electrolytes Density of matrix through which ions pass Poly(ethylene glycol) dimethacrylate Li +

8. Switch speed determined by Concentration of Li+ electrolytes Density of matrix through which ions pass

9. Lithium Electrolyte IrO2 film hooked to positive = oxidation = removing Li+ from IrO2 film = absorbs light = appears dark

10. Lithium Electrolyte IrO2 film hooked to negative = reduction = pulling Li+ onto IrO2 film = clear

11. Side reaction of concern desired redox: reaction with water:
