Onion Vesicles Under the Microscope

Caption: University of Pennsylvania researchers have shown that a certain kind of dendrimer, a molecule that features tree-like branches, offers a simple way of creating vesicles and tailoring their diameter and thickness. Moreover, these dendrimer-based vesicles self-assemble with concentric layers of membranes, much like an onion. Here, black and white CryoTEM images of the vesicles were turned into colorized 3-D models to better show their layers.
