New Surfaces for the Control of Endothelial Cell Function: Application in the Design of Biocompatible Stents. Using dewetting of thin polymer films, the present proposal will develop new structured biocompatible surfaces with controlled chemistry and topography, which will allow the growth of a normal (non-activated) monolayer of endothelial cells. Sophisticated molecular parameters will be used to assess that endothelial cells maintain their normal quiescent phenotype.

Using dewetting of thin polymer films, the present proposal will develop new structured biocompatible surfaces with controlled chemistry and topography, which will allow the growth of a normal (non-activated) monolayer of endothelial cells. Sophisticated molecular parameters will be used to assess that endothelial cells maintain their normal quiescent phenotype. The project sets the ground work for the design of improved, more biocompatible structured stents to minimise the abnormal growth of cells on and around the stent, thereby reducing the occurrence of vascular complications. Thus this research could improve the success rate of stents implanted into patients with cardiovascular disease and reduce health costs.Read moreRead less

Soft solids rheology and filled elastomeric networks. Elastomeric networks that have imbedded particles are considerably more difficult to model than unfilled networks because the imbedded particles deform the trajectory of the chains. Any treatment must incorporate this dual nature of the network. Our work will address this important issue with particular reference to two important materials - liquid crystalline elastomers and bread dough. We aim to produce an accurate mathematical description ....Soft solids rheology and filled elastomeric networks.

New Types of Biomimetic Nanostructured Adhesives. Adhesives are one of the main ways in which we join materials, and have many advantages over other methods of joining. In this work we will make a new class of adhesive using nanotechnology that attempts to copy the very fine-haired feet of animals such as geckos who can stick to almost any surface, under most conditions. We will make these adhesives over large surface areas, and thus they will have commercial possibilities in a range of high tec ....New Types of Biomimetic Nanostructured Adhesives. Adhesives are one of the main ways in which we join materials, and have many advantages over other methods of joining. In this work we will make a new class of adhesive using nanotechnology that attempts to copy the very fine-haired feet of animals such as geckos who can stick to almost any surface, under most conditions. We will make these adhesives over large surface areas, and thus they will have commercial possibilities in a range of high technology industries, as well as in harsh environments. Because we will be able to manipulate the structure and observe property changes, it should also give us a greater insight into the adhesion mechanisms used by many small animals and bugs.Read moreRead less
