Synthesis of block copolymer B (BCP‐B) and characterization of Psome B. a) Reaction scheme, composition, molecular weight, and dispersity (Ð) of BCP‐B. ¹Determined by ¹H‐NMR spectroscopy;² Determined by GPC. b) Reversible swelling/deswelling of Psome B at pH 4.0 and 7.0 in water solution at ≈10 × 10⁻³ m NaCl by DLS. c) DLS–titration data of 0.5 mg mL⁻¹ Psome B in water solution at ≈10 × 10⁻³ m NaCl (• Diameter from DLS, — Logistic fit of the curve). d) Cryo‐TEM image of Psome B, scale bar: 200 nm. Average diameter ≈ 120.6 ± 32.3 nm and membrane thickness ≈ 26.9 ± 2.9 nm, taken from more than 100 polymeric vesicles.
