(a) Scattering curves of bare P2 (10 g/L, blue) and P2 with PTX (10 and 4.8 g/L, red) and their fitting curves assuming a homogeneous sphere (solid line) or a raspberry form (dashed line). Curves are shifted in intensity for better visibility. (b) All radii from SANS measurements of P2 solutions in D2O (c = 10 g/L at 37 °C) with varying PTX concentrations. Sketches indicate if homogeneous spheres or raspberry-like micelles were applied for the fitting process. Open circles: radii of spherical micelles, solid circles: radii of raspberry-like micelles, Rmic, open triangles: radii of the embedded PTX particles, RPTX.
