- Title
Materials science: Pulsating vesicles.
- Authors
van Hest, Jan C. M.
- Abstract
The article discusses the discovery of polymeric vesicles and examines their structure and properties. Researchers found that it breathes in response to potential of hydrogen (pH), becoming twice as big in acid solution as it is in basic solution. They said that this reversible size change comes with a permeability change, so that water molecules diffuse more easily through the membrane wall of the vesicle when the structure is high swollen. They added that these vesicles can be considered as nanometrescale containers, in which a molecular shell or membrane encloses an aqueous interior.
