Φrat for the amyloid solution is Φ of the dye with amyloids divided by Φ of the dye in H2O/DMSO mixture. Φrat for glycerol is Φ of the dye in glycerol solution divided by Φ of the dye in methanol. Data for glycerol are taken from ref (26).
Details on concentrations and v/v ratios between solvents for each dye are presented in the Experimental Section in the Supporting Information file.
