a, c Representative scanning electron microscopy (SEM) images of S. elongatus and PEDOT-S/S. elongatus biocomposites after photocurrent collection in a photoelectrochemical experiment, respectively. The imaging experiments were independently repeated three times with similar results. b, d Cross-sectional SEM images of S. elongatus and the PEDOT-S/S. elongatus biocomposites, respectively. e Schematic representation of the microstructure of S. elongatus and PEDOT-S/S. elongatus biocomposites. f, g Z-stack imaging of S. elongatus and PEDOT-S/S. elongatus biocomposites at a depth of 30 μm performed using confocal laser scanning microscopy (CLSM), utilizing the intrinsic fluorescence of chlorophyll within the S. elongatus cells (λexc = 620 nm, λemi = 650–750 nm), which are shown as red dots.
