a CA curves of 1 mM Fe(CN)64– and 0.1 M KCl in various agarose hydrogel concentrations (colored lines) and in solution (black line) at an applied potential of 0.3 V using a Au disk electrode. b Plots of current as a function of the t–1/2 of (a) and highlighted long-term domain (inset). The gray dotted circle showed the current fluctuations due to the natural convection
