Perforated Block Copolymer Vesicles with a Highly Folded Membrane (original) (raw)

This research presents the observation of highly perforated vesicles formed from the diblock copolymer, poly-(ethylene oxide)-block-poly(3-(trimethoxysilyl)propyl methacrylate) (PEO-b-PTMSPMA). Utilizing electron microscopy and transmission electron microtomography, the study reveals a complex internal structure characterized by highly folded bilayers and pores, contrasting with simpler vesicle forms previously documented. The vesicles' formation was influenced by the addition of triethylamine, which triggered a gelation process, resulting in stable hybrid hollow particles with distinct morphological features.
