This proposal is to perform further SANS contrast measurements on three protein/DNA interactions currently worked on at the Research Complex at Harwell. This is part of an...

The spontaneous formation of multilayer structures at interfaces from surfactant self-assembly is now emerging as an important structural signature associated with a wide range...

Perfluoroalkyl substances (PFASs) are stable compounds and commercially desirable. They are widely used, for example, as surfactants in textile and paper products and in aqueous...

Cell adhesion and proliferation at the surface of liquids such as oil droplets is a surprising phenomenon as it is typically accepted in the field of bioengineering that cells...

This study will focus on the structural investigations of the bilayers formed on silicon substrates in which the outer leaf consists of DOPE/LPS mixtures. We aim is to achieve...

Hydrophobins, hfb2, are secreted fungal proteins in the form of a small lipopeptide. They are strongly surface active and self-assemble in solution and at interfaces. They have...

This proposal is part of a broad programme of collaborative research between RAL / Oxford and Unilever, using predominantly scattering techniques to investigate the nature of...

We propose to make neutron reflectivity measurements of the weak polyelectrolyte, poly(dimethy amino ethyl methacrylate), grown from two different surface densities of initiator...

We have designed a series of cationic peptides with different helix repeats that can kill bacteria but remain benign to mammalian host cells. The selectivity to cell types is...

Lysosomes are subcellular organelles with acidic interiors (pH 3.5-5), containing enzymes that break down macromolecules and intracellular waste. Controlled release of lysosomal...

We have previously shown that peptides such as G(IIKK)4I-NH2 (G4) can kill bacteria and inhibit cancer cell growth whilst remaining benign to mammalian host cells. We have also...

This proposal presents to directly measure ¿bridging¿ of anionic surfactants on an anionic surface through multivalent ions from water under well-controlled conditions (pHs and...

In this part of the proposed work, we wish to explore how antibiotics and antimicrobial peptides interact with model lipid bilayers in the form of a supported lipid bilayer,...

This proposal constitutes part of our ongoing study towards understanding how keratin, an important protein component of hair and skin, interacts with ionic surfactants using...

This proposal constitutes part of our ongoing study towards understanding how collagen based polypeptides interact with ionic surfactants using SANS. Both SDS and C12TAB will be...

Neutron reflection (NR) is well established for studying molecular films such as lipid monolayers. Its high depth resolution combined with deuterium labelling can determine the...

We propose to use the new SANS2d to study the dynamic structural evolution in the couse of the formation of DNA-cationic polymer complexes. The dynamic process and the mixing...

Lipopeptide surfactants are highly effective at reducing interfacial tension. However, there is a general lack of understanding of the relationship between their molecular...

Low molecular weight gelators (LMWG) form hydrogels via self-assembly in water under specific conditions to form long, fibrillar structures. Non-covalent forces interactions...
