Nanotubes from pore‐spanning membranes : a site‐specific experimental procedure is introduced that allows determination of the lateral tension and bending modulus of pore‐spanning bilayers in a single force cycle comprising indentation followed by nanotube formation upon retraction. With this technique, a quantitative mapping of intrinsic local elastic properties comes into reach.
