Hydrogel Stamping of Arrays of Supported Lipid Bilayers with Various Lipid Compositions for the Screening of Drug–Membrane and Protein–Membrane Interactions

Stamping on fat: Agarose gel stamps were used to create ≥100 membrane arrays (see picture) by using only picomolar amounts of lipids. This constitutes a rapid and straightforward method for the fabrication of functional membrane arrays with a variety of lipid compositions which can be used for screening assays, for example, for drug–membrane interactions.
