The hydration and ordering of lamellar block copolymer films prior to the for...
For polymer vesicles to act as effective molecular delivery systems we must efficiently encapsulate a molecular payload within the vesicle. We would like to use neutron... -
Planar bilayer formation on novel cationic surface suitable for membrane prot...
Membrane receptor proteins (MRPs) which are thought to represent the majority of drug targets are challenging to study as their structure and function is dependent on being... -
SANS studies of mixed phospholipid:sterol vesicles and their interaction with...
The increasing incidence of pathogenic fungi resistant to treatment with amphotericin B (AmB) has created a demand for novel anti-fungal agents that can circumvent the... -
Floating Lipid Bilayers Created by Vesicle Fusion
'Floating LSupported Bilayers' (FSB's) have become the 'standard' systems used for studying membrane systems using reflectivity at ISIS and other facilities. They are reliable,... -
The hydration and ordering of lamellar block copolymer films prior to the for...
The key to the use of polymer vesicles as effective molecular delivery systems is in the ability to efficiently encapsulate a molecular payload within the vesicle. We would like... -
Measuring phospholipid flip-flop rates across vesicle bilayers
Asymmetry across biological membranes is vital for a wide range of organelle and cellular functions. Significant differences in lipid composition have been found between the... -
A biophysical approach of studying the molecular interactions of a novel anti...
Gram negative (-ve) bacteria possess numerous defenses against antibiotics, not the least of them being the intrinsic permeability barrier afforded by their outer membrane (OM)... -
Complex evolution of solution microstructure in LAS / nonionic surfactant mix...
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... -
Phospholipid exchange between tethered bilayers and vesicles
Our objective is to create asymmetric solid surface tethered bilayers (tBLMs) with the the outer leaflet predominately populated by charged phospholipids. tBLMs are produced by... -
Structure of siRNA containing delivery vehicles: effect of serum
Complexes prepared from cationic, dichain lipid (L) vesicles and negatively charged siRNA (R), with and without positively chargely targeting peptides (P) known as LR or LPR... -
SANS studies of Amphotec (aggregates of amphotericin-cholesteryl sulfate)
The anti-fungal agent amphotericin B (AmB) can be administered to patients in aqueous solution complexed with cholesteryl sulfate (CS), and this formulation helps to minimise... -
Surface modification in heteropolymer blends.
In recent years we have had considerable success with the surface modification of amorphous and crystalline thermal plastic polymers using multi-end functional additives. In... -
Introducing the O-antigen into Bacterial Outer Membrane Models
The Gram negative bacterial outer membrane protects the bacterium from external toxins such as antibiotics. This is partially responsible for Gram negative bacteria becoming the... -
Self-assembled Floating Lipid Bilayers: What Forces Are Causing the Bilayer t...
Recently (RB19100102) we have discovered that floating bilayers composed of fluid phase lipids can be produced by deposited vesicles onto charge modified oligo(ethylene... -
SANS studies of mixed phsopholipid:sterol vesicles and their interaction with...
The increasing incidence of pathogenic fungi resistant to treatment with amphotericin B (AmB) has created a demand for novel anti-fungal agents that can circumvent the... -
Peptide resistance in asymmetric MRSA-mimetic vesicles
We have been investigating the influcence of the cationic staphylococcal lipid lysyl-phosphatidylglycerol (L-PG) on bacterial resistance to antimicrobial peptides (AMPs). Using... -
Binding of DNA to Model Membranes in the Presence of Ca2+ Ions and a Membrane...
The aim of the present work is to gain an understanding of the interaction of DNA with the phospholipid bilayers. The effect of different forms of DNA, the presence of divalent... -
Antimicrobial peptide-loaded nanogels and their interaction with lipid bilayers
Due to increasing antibiotic resistance, bacteria membrane disrupting antimicrobial peptides (AMPs) are of increasing interest as alternatives to classical antibiotics. AMPs are... -
Adsorption of perfluoroalkyl substances to solid soil interface to elucidate ...
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...
