Swelling of polyelectrolyte multilayer-supported lipid layers. 1. Layer stability and lateral diffusion

Article Abstract:

The fluorescence recovery after photobleaching (FRAP) is used to investigate the influence of solvents on the stability and mobility of polyelectrolyte multilayer (PEM)-supported lipid layers. The conclusions on charged polymeric systems complement investigations of uncharged polymer-supported model membranes and demonstrate the significance of local electrostatic interactions for issues of stability and dynamics.

Competition between a macroion and a polyelectrolyte in complexation with an oppositely charged polyelectrolyte

Article Abstract:

Monte Carlo simulations are used to study the competition between a spherical macroion and a polyelectrolyte in complexation with an oppositely charged flexible polyelectrolyte. The effect of the polyelectrolyte length, flexibility, and linear charge density on the macroion release is examined.

Osmotic coefficient of a synthetic rodlike polyelectrolyte in salt-free solution as a test of the Poisson-Boltzmann cell model

Article Abstract:

A comparison of the osmotic coefficient of a synthetic stiff-chain polyelectrolyte with the prediction of the Poisson-Boltzmann (PB) cell model is presented. The data demonstrate that the PB cell model captures the essential features of the experimental results without adjustable parameters.c
