Aligning a Single‐Lipid Nanotube with Moderate Stiffness

Bendy tubes: Lipid nanotubes can be aligned by a novel and simple method, whereby a fine line of a single nanotube is drawn freely by microinjecting the aqueous dispersion onto a glass plate. This technique is simple and highly adaptable; even words can be written (see picture)! The tubes can be bent and their Young's modulus measured by manipulation with optical tweezers.
