Influence of Polyelectrolyte Multilayer Properties on Bacterial Adhesion Capacity

Elasticity of polyelectrolyte multilayer microcapsules.

We present a novel approach to probe elastic properties of polyelectrolyte multilayer microcapsules. The method is based on measurements of the capsule load-deformation curves with the atomic force microscope. The experiment suggests that at low applied load deformations of the capsule shell are elastic. Using elastic theory of membranes we relate force, deformation, elastic moduli, and charact...

Selective Primary Hepatocyte Adhesion on Polyelectrolyte Multilayer : Template forPatterned Cell Co-Culture

Introduction The ability of surfaces to modulate cellular behavior such as adhesion, migration, proliferation and differentiation is an important facet of tissue and organ formation and in the eventual realization of functional biomaterials. The presence of micro or nanostructures on a surface permits the manipulation of cell-substrate and cell-cell interactions to better control cellular funct...

Cell adhesion on polyelectrolyte multilayer coated polydimethylsiloxane surfaces with varying topographies.

This article demonstrates that the micro-topography of the surface with respect to the pattern size and pitch influences cell adhesion and proliferation. Extensive research has shown the dependence of cell proliferation on substrate chemistry, but the influence of substrate topography on cell attachment has only recently been appreciated. To evaluate the effect of substrate physical properties ...

Controlling primary hepatocyte adhesion and spreading on protein-free polyelectrolyte multilayer films.

The development of new methods for fabricating thin films that provide precise control of the three-dimensional topography and cell adhesion could lead to significant advances in the fields of tissue engineering and biosensors. This Communication describes the successful attachment and spreading of primary hepatocytes on polyelectrolyte multilayer (PEM) films without the use of adhesive protein...
