Fig. 1. PHB-derived microparticles with encapsulated DS: microparticles loaded with paclitaxel (A); microparticles loaded with doxorubicin (B); coumarin crystals on the surface of a microparticle loaded with this substance (C); microparticles loaded with methotrexate (D)
Fig. 2. А. A schematic representation of chain packing in single PHB crystals (Iwata T. et al. [9]). B. The rough (a) and smooth (b) surfaces of a macroscopic PHB film and the cross-section of a lamellar stack (marked with a green arrow) (c). C. A topographic image of an ultrathin PHB film; the crystalline structure of the polymer can be clearly seen [19]
