    • As reference experiments, we prepared samples by using other polysaccharides instead of SPG, for example, dextran, plullan, and starch. However, PS precipitated out of solution immediately after adding water in the presence of these polysaccharides and the formation of a stable emulsion could not be confirmed. The results imply that the strong tendency for SPG to form a helical structure is indispensable for the formation of a stable emulsion

    • We prepared a mixed solution containing PS and t-SPG instead of sSPG. However, the mixture resulted in a precipitate immediately after mixing the two components. These findings imply that the renaturing process from s-SPG to t-SPG is indispensable for the formation of a stable emulsion

    • Here we prepared an O/W emulsion by using 100.0 μL of PDAN in toluene solution in which the PDAN concentration was 10.0 mM. The emission peak of PDAN shifted to a longer wavelength with increasing solvent polarity, for example, 390 nm in cyclohexane, 450 nm in dimethylformamide, and 520 nm in water
