TOTO-1 particle shown in SI Appendix, Fig. S6C and its neighboring particles. Intensity (Left) and orientation of polarized fluorescence of TOTO-1 particles overlaid on intensity image (Right) as magenta lines. Lengths of the lines are proportional to polarization factors (p) of particles. *The particle shown in SI Appendix, Fig. S6 B–G . (Scale bar: white, 1 µm; magenta, p=1.)
