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 materials containing hierarchy via 3D sacrificial micro-moulding. The project seeks to develop sophisticated new polymeric materials and devices not possible using current manufacturing techniques. Biomaterials based on hydrogels are ideal substrates for synthetic extra-cellular matrices due to their high water content.

The project seeks to develop sophisticated new polymeric materials and devices not possible using current manufacturing techniques. Biomaterials based on hydrogels are ideal substrates for synthetic extra-cellular matrices due to their high water content. However, one of the challenges hindering the use of hydrogels is reproducing the transport properties found in natural tissue with hierarchical features such as vascularisation. To address this, the project plans to develop a 3D moulding process for generating soft materials containing precise channels decorated with defined molecules. Intended outcomes include a fundamental understanding of the 3D moulding process, and new polymers and advanced tools for bioengineers for future applications such as tissue transplants, cell guides for treating spinal cord injuries, soft robotics and microfluidic devices to study cancer metastasis.

Effect of a novel immobilised antimicrobial peptide on bacteria. This project plans to investigate a novel cationic peptide that prevents microbial colonisation of surfaces. The ability of bacteria to colonise surfaces affects almost all aspects of human life – from water to food and medical devices.

The ability of bacteria to colonise surfaces affects almost all aspects of human life – from water to food and medical devices. As microbes become increasingly resistant to traditional biocides, the design of effective antimicrobial surfaces to prevent microbial colonisation and biofilm formation is critically important. The novel cationic peptide may provide a solution, but the mechanism of action of surface-bound peptides on bacteria is poorly understood. This project aims to combine biophysics, biochemistry, microbiology and molecular biology to study interactions with the surface of two model bacteria. This may facilitate optimal design of new coatings.Read moreRead less
