Potential technological applications for artificial lipid and proteo-lipid membranes, such as capsules for controlled delivery of drugs and coatings for biosensors and biomaterials, are in many cases limited by the inherent instability of lipid lamellar phases. Development of methods to stabilize artificial lipid membranes has therefore been a focus of research efforts since the 1970s. Linear and...
An overview of molecular models and computer simulation techniques for amphiphilic vesicles formed either by lipid or block copolymer molecules is presented. First, system-specific, atomistic or coarse-grained representations of amphiphilic vesicles, which account for the detailed, chemical structure of the system, are briefly considered. The common features of collective phenomena on the mesoscale...
Amphiphilic block copolymer membranes, classified as vesicles, are nano-aggregates receiving a lot of scientific interest due to their wide range of potential applications extending from biomedicine (e.g., drug delivery, imaging, nanoreactors) to material science (biosensors, electronics). This chapter summarizes the principles of vesicle formation, various membrane-forming copolymer systems and their...
Polymer-tethered membranes combine fascinating structural, dynamic, and viscoelastic properties. Many important insights into these peculiar supramolecular systems can be obtained from studies on polymer-tethered monolayers. This chapter discusses recent experimental findings on polymer-tethered monolayers at the air–water interface. In particular, Langmuir monolayers which are comprised of pure lipopolymers...
This review covers the major processes and mechanisms involved in the production of biohybrid or peptide-based polymer vesicles by self-assembly. The formation of vesicles conventionally occurs based on geometric packing issues, and becomes predominant when the membrane-forming segment is stiffened due to hydrogen bonding and secondary structure interactions or supramolecular complexation. The vesicles...
This contribution describes the assembly and structural and functional characterization of various types of polymer-supported lipid bilayer membranes.We start with the description of the polymer-cushioned membrane that can be prepared by first attaching (covalently) polymer coils (as tethers or cushions) from solution to a reactive solid support, followed by the covalent coupling of a lipid monolayer...
