Fig. 4. Effect of the PB concentration on the FWHM values measured along the x-axis (blue dots) and the y-axis (red squares) of the bead as defined in Fig. 3a. The values were extracted from the side-view images of single 12 μm [Ru(bpy)3]2+-decorated polystyrene beads. Error bars show the standard deviation (n = 9). Lines are only a guide to the eye.
