Research output: Contribution to journalArticle


Native vesicles or "reduced protocells" derived by mechanical extrusion concentrate selected plasma membrane components, while downsizing complexities of whole cells. We illustrate this technique, characterize the physical-chemical properties of these reduced configurations of whole cells, and demonstrate their surface immobilization and patternability. This simple detergent-free vesicularized membrane preparation should prove useful in fundamental studies of cellular membranes, and may provide a means to engineer therapeutic cells and enable high-throughput devices containing near-native, functional proteolipidic assemblies.
