    Notes: Nach bedeutenden Fortschritten in der Flüssigkristall- und Polymerforschung interessierten sich Wissenschaftler vermehrt für lyotrope Systeme. So wurden das Phasenverhalten und die Stabilität kolloider Teilchen, die wasserlösliche oder oberflächenadsorbierte Polymere oder Block-Copolymere enthalten und als Suspensionen vorliegen, studiert. Am häufigsten untersucht wurden Micellen, Latexteilchen und Lipidvesikel (Liposomen). In Gegenwart hydrophiler Polymere aggregieren und verschmelzen Liposomen. Werden Blockcopolymere von Liposomen adsorbiert oder Tenside mit großen, polymeren polaren Kopfgruppen in die Liposomenmembran eingebaut, so sind die Eigenschaften der Liposomen aufgrund der schlecht definierten Natur solcher Systeme schwer zu erklären. Liposomen mit Diacylgruppen enthaltenden Tensiden, die längere Polymerketten kovalent gebunden haben, zeigen viele neue Eigenschaften, die sowohl für die Grundlagenforschung als auch für mögliche Anwendungen von Bedeutung sind. Sie ermöglichen z.B. das Studium von Phasenverhalten und Polymerkonformation, von Skalierungsgesetzen, von Kolloid- und Oberflächeneigenschaften sowie von Zellfunktionen; unter Anwendungsgesichtspunkten steht die Verwendung von Liposomen als Wirkstofftransportsysteme im Vordergrund. Während in der Grundlagenforschung die Theorie weiter ist als das Experiment, hinkt der medizinischen Anwendung das theoretische Verständnis hinterher. Erst relativ spät wurde entdeckt, daß Liposomen in biologischem Milieu - für ihre Verwendung als Wirkstoffträger unvermeidbare Bedingungen - bedeutend stabiler sind, wenn sie mit bestimmten Polymeren beschichtet werden. Durch diese Erkenntnis wurden Anstrengungen, Liposomen in der Krebstherapie und für den gezielten Wirkstofftransport einzusetzen, wiederbelebt. All dies war nur durch effektives und synergistisches Zusammenspiel mehrerer wissenschaftlicher Fachgebiete möglich.

    Notes: After significant developments in liquid crystal and polymer research, scientists became interested in lyotropic systems containing polymers. These studies investigated, for instance, phase behavior and stability characteristics of suspensions of colloidal particles containing water-soluble or surface-adsorbed polymers or block copolymers. The most frequently studied were micelles, latex prticles, and lipid vesicles (liposomes). Liposomes aggregate and fuse in the presence of hydrophilic polymers but their properties were difficult to explain when block copolymers were adsorbed or surfactants with larger polymeric polar heads were inserted into the liposome membrane, because such systems are inherently ill defined. Liposomes containing diacyl surfactants with covalently linked, longer polymer chains display many new properties with very important consequences for both basic and applied research. They stimulate fundamental studies on phase behavior and polymer conformation, scaling laws, colloidal and surface properties, and cell function: applications deal predominantly with liposomes as drug delivery systems. While in basic research theory is currently more advanced than experiment, in medical applications theoretical understanding lags behind experimental achievements. It was discovered only relatively late that liposomes with an appropriate polymer coating are significantly more stable in a biological milieu, a necessary condition for their utility as drug carriers. In particular in medical applications, this practice has rejuvenated the field of anticancer therapy and targeted drug deliviery. All these advances were made possible by an effective and synergistic overlap of many different disciplines.
