Abstract: The present invention relates to a method for preparation of monodisperse cell-targeting giant unilamellar vesicles based on symmetrically division of a parent polymer shell-stabilized giant unilamellar vesicle into smaller polymer shell-stabilized giant unilamellar vesicles with a diameter between 1 ?m and 10 ?m using a microfluidic splitting device. The inventive method allows preparation of differently charged giant unilamellar vesicles as well as bioligand- and PEG-conjugated giant unilamellar vesicles, which are useful for targeted cellular delivery at high efficiency and specificity. A further advantage of the present invention is that the giant unilamellar vesicles can deliver huge cargos such as drug releasing porous microparticles, high amounts of in vivo imaging probes, viruses, or up-and-coming DNA origami robots.

Abstract: A method and apparatus for characterizing the surface form of an optical element, in particular a mirror or a lens element of a microlithographic projection exposure apparatus, includes: carrying out a plurality of interferometric measurements, in each of which an interferogram is recorded between a test wave emanating from a portion of the optical element in each case and a reference wave, the position of the optical element relative to the test wave being altered between these measurements, and calculating the figure of the optical element on the basis of these measurements. This calculation is carried out iteratively such that, in a plurality of iteration steps, the figure of the optical element is ascertained in each case by carrying out a forward calculation, each of these iteration steps being based in each case on a reference wave that was adapted based on the preceding iteration step.
