Supported membranes on soft polymer cushions: fabrication, characterization and applications

Soft biofunctional and biocompatible interfaces on solids designed by the deposition of ultrathin soft polymer films or supported membranes have numerous scientific and practical applications, These include the immobilization of glycolipids, membrane receptors and proteins to generate models of cell and tissue surfaces. Powerful surface-sensitive techniques can be applied to study protein-protein recognition processes at membranes and the control of cell adhesion by the interplay of specific 'lock-and-key' forces and universal interfacial forces. Potential practical applications include the design of smart biosensors based on electro-optical devices and the fabrication of biofunctional surfaces for the stimulation of cell proliferation and tissue growth, or for the suppression of apoptosis.
