Influence of PVP concentration on hydrodynamic diameter of CPT core (5) and amounts of polyelectrolyte needed for recharging their surface upon adsorption: 1 – first step: Hep on BSA-stabilized CPT cores; 2 – second step: PLB16-5 on CPT/Hep nanoparticles; 3 – third step: Hep on CPT/Hep/PLB16-5 nanocapsules, and 4 – fourth step: P16-5 on CPT/(Hep/PLB16-5)1.5 nanocapsules. pH 3.0. CBSA = 0.64 mg/mL.
