Figure Lengend Snippet: Schematic of Pt–Au bimetallic system that catalyzes the decomposition of hydrogen peroxide yielding ionic species which generate an electric field (red streamlines) that drives fluid flow (black streamlines). L = 10 mm is the length of bielectrode, and H is the height of the cell, where H = 1500 μm for the FLIM setup and H = 500 μm for the fluid flow setup.

Figure Lengend Snippet: Lifetime vs proton concentration and calibration curve for FLIM measurements on semilog scale. Data was plotted within the pH range 5–6, where the fluorescence dye is sensitive to protonation. Solid line corresponds to the best fit to a Boltzmann sigmoid model, and the dashed lines refer to the 95% confidence interval.

Figure Lengend Snippet: Proton concentration profile along the junction of the bielectrode for simulation (bulk pH 5.62) at channel heights and FLIM results. The solid lines represent the simulation results, and the open symbols depict the FLIM data. The distance was nondimensionalized by the length of the bielectrode, L = 10 000 μm. The proton concentration was averaged at the electrode for FLIM.
