Figure 2: Formation of a lipid bilayer membrane.
From: Arrayed lipid bilayer chambers allow single-molecule analysis of membrane transporter activity

(a) Schematic illustration of lipid membrane formation processes. In these processes, unilamellar lipid bilayer membranes formed on the inlet of individual chambers. (b) Fluorescent image of Alexa 488 encapsulated into microchambers sealed by lipid membranes.
