Biopolymer multilayers.

Multilayers are formed by the alternate deposition of polyanionic and polycationic polymers, and have potential applications within surface modifications, optical devices and separation membranes. Surface topography might influence the biocompatibility, adhesive and optical properties of these systems. We are therefore looking at how molecular properties of biopolymers and preparation conditions are influencing the surface topography of biopolymer multilayers. Part of the work includes developing routines for user-independent, quantitative extraction of parameters for analysis of the surface topography.
