Media is any form of research output that is recorded and played. This is most commonly video, but can be audio or 3D representations.
Spontaneous generation of DNA-enclosing liposomes from a DNA–lipid blend film is investigated. The special properties of the lipid vesicles, namely, micrometer size, unilamellarity, and dense polymer encapsulation acquired by the dehydration–rehydration process, are physicochemically revealed. We found that the formation of giant unilamellar vesicles encapsulating DNAs are governed by micropatterns of the films, such as dots and network patterns. From the results, we proposed a plausible physical mechanism for the dehydration–rehydration process, making it possible to optimize the encapsulation of any agent.
