Mitochondria are not only the powerhouse of the cell, but are also involved in cellular suicide via apoptosis (programmed cell death). The mitochondrial apoptotic pathway is a...

Hydroxyl radicals may be used as disinfection agent in the advanced oxidation processes or tertiary treatment of waste and occasionally drinking water. We very recently oxidised...

Understanding how nanoparticles interact with lipid bilayers will potentially have high impact on the development of new drug delivery systems, and on the investigation of their...

One of the main challenges in spintronics research is to provide a link between magnetic elements and conventional electronic circuits. A novel approach to this old problem is...

Migration of small molecules to, and across the surface of polymer matrices is a little-studied problem with important industrial applications. PVAc films are of industrial...

Accurate, safe and cheap hydrogen detectors functioning under a wide range of conditions are a vital ingredient for using hydrogen as an energy carrier. A novel, safe and cheap...

This proposal addresses bilayer swelling experiements on floating supported bilayers (FSBs) in the presence of biological buffers. Previous work on multilamellar vesicles has...

Antibody-antigen binding has been extensively used in many technological applications such as immunoassays, chemical analysis and bionanotechnology. The crucial element...

Polyoxometallates (POM) are well defined transition metal clusters with a range of interesting catalytic, magnetic and optical properties. To make efficient use of these...

The balance of proteins adsorbed at a surface is important in a wide range of situations, e.g. implants, nanoparticles. The accepted model is that rapidly diffusing proteins...

Membrane bound proteins continue to be to date the most elusive molecules in nature, since they are only functional in the lipid bilayer. We have developed a method to study...

The gram-negative bacterial membrane is of extreme medical importance. Two of its major components are lipopolysaccharides (LPS's) and integral membrane proteins. Porins are...

EuO is the ferromagnetic oxide semiconductor with the highest demonstrated value of conduction band exchange splitting (0.6 eV), which makes it at present one of the most...

pH-responsive polymer brushes comprise of long polymer chains of either a weak acid or base chemically attached to a surface. Depending upon the degree of ionisation along the...

We have been studying the formation of solid polymer-surfactant films formed from cationic surfactants with PEI. We wish to use the highly organised mesostructures formed in the...

The Outer Membranes (OM) is a feature of many pathogenic bacteria. It is important as a barrier to antibiotics & the site of human-bacteria interaction. However bacteria are...

Following our previous study of adsorption of globular lysozyme and BSA at the oil/water interface by neutron reflection, we continue to explore how unfolding of globular...

Human dihydroorotate dehydrogenase (DHODH) is an integral membrane protein found in mitochondria involved in the biosynthesis of pyrimidines. DHODH oxidizes dihydroorotate with...

The redox driven swelling and deswelling of conducting polymers has been termed Electronic Muscle actuation. One application of this property is as a sphincter-like valve in a...

A technique we have recently developed enables us to simply produce stable, homogenous and thin oil layers, using polymer surfactants, in a simple manner on water. These are...
