Abstract

original image

Bionanopartikel wie der Augenbohnen-Mosaikvirus können Öltropfen in wässriger Lösung durch Selbstorganisation an der Flüssig-flüssig-Grenzfläche stabilisieren. Anschließende Vernetzung der Bionanopartikel liefert robuste Membranen mit kovalenten Verknüpfungen zwischen den Partikeln. Diese Membranen haben einen Durchmesser im Nanometerbereich (siehe SANS-Bild (SANS=small-angle neutron scattering)) und werden mithilfe von Fluoreszenzmarkierung untersucht.
