Morphology and size of DOXMS2 and MS2 spheres. SEM analysis of a DOXMS2 and b MS2 particles that were formed by mixing silk at an initial concentration of 2.5 mg/mL with 2 M potassium phosphate buffer, pH 8. Scale bar—1 µm. c The mean size of the spheres was calculated by measuring the diameter of 100 particles in SEM images. The mean and standard deviation of three independent experiments are shown
