a
Determined by DLS analysis, concentration 4 mg mL–1.
b
Determined by SAXS analysis using the Guinier–Porod model in Igor software, concentration 0.5 mg mL–1.
c
Determined by the Guinier–Porod model; 0 means spherical micelles, 1 is for rodlike micelles, and 2 is for platelike micelles. The model is more accurate for hard micelles but can still give information for softer or looser assemblies.
d
Poor sample collection did not provide raw data of good quality.
