Competitive adsorption in hydrophobin-surfactant mixtures
Hydrophobins are small compact secreted fungal proteins which are strongly surface active and adhere to both hydrophobic and hydrophilic surfaces. Their strong surface activity... -
Manipulating surface adsorption of SLES surfactants using temperature
Although surfactant detergency is well understood above 30 C, actions of surfactants below 30 C are not well established. In the era of energy saving and environment caring, we... -
Co-adsorption and competitive adsorption of eggshell membrane polypeptide aga...
In this work we explore how to use neutron reflection to study the interfacial adsorption from a natural eggshell membrane polypeptide at the oil/water interface. We will then... -
Interplay of apoptosis regulating Bcl-2 proteins at mitochondrial membranes u...
Mitochondria are not only the powerhouse of the cell, but are also involved in cellular suicide via apoptosis (programmed cell death). This pathway is a major regulator in cell... -
Membrane-stacking properties of myelin proteins
Myelin is the multilamellar structure that ensheaths axons and accelerates nervous impulses in the nervous system. The fine structure of myelin remains to be further... -
Lipid bilayers suspended beneath the air/water interface for neutron reflecti...
Bacterial membranes contain safety valves called mechanosensitive ion channels, which protect the bacterium from changes in the osmotic pressure of their environment. However,... -
Surface properties of biogenic polyamine-surfactant mixtures
Polyions and biogenic polyamine are ubiquitous in many important biochemical functions. We propose here to use neutron reflectivity to investigate their potential to induce and... -
Spontaneous multilayer formation at interfaces in mixed surfactant systems
The spontaneous formation of multilayer structures at interfaces from surfactant self-assembly has until recently been rarely observed. However, surface multilayer structures... -
The role of biogenic amines in lipopeptide biofilm formation
Pore forming lipopeptides, such as Tolaasin, are produced by pathogenic mushroom bacteria, and are implicated in diseases such as ¿brown blotch¿ disease. They have potential... -
Nature of the protein corona on nanoparticle surfaces
When nanoparticles enter a biosytem they rapidly acquire a protein corona. The nature of the outer part of this corona will determine the response of the biosystem to the... -
How perfume structure affects surface coadsorption with anionic surfactants
In a recent EPSRC / Unilever / Oxford CASE project we have used NR to explore and develop optimised delivery mechanism for active benefit agents such as perfumes. In particular... -
Mixed H/F-Carbon surfactant monolayers for fire-fighting applications
The aim is to use Neutron Reflectivity (NR) to gain essential information on the adsorption properties of fluorocarbon/ hydrocarbon mixtures in commercial fire-fighting foam... -
Interfacial conformation of antibody and antigen binding capacity
Antibody-antigen binding has been extensively used in many technological applications such as immunoassays, chemical analysis and bionanotechnology. The crucial element... -
The origins of Biosurfactant self assembly
Biosurfactants are becoming more commonplace in pharmaceuticals, vaccines and other forms of medicines. With the biobased economy growing substantially and pressure to reduce... -
Surface structure of ethoxylated PEI/SDS mixtures: optimising surface properties
The strong interaction between polyelectrolytes and ionic surfactants can result in pronounced surface adsorption and the formation of surface multilayer structures. This... -
The Effect of the Head Group on Multilayering of Alkanoic Alkyl Ester Sulphon...
We have shown that under certain conditions multilayer adsorption of surfactants occurs at the air-water interface. in which case the system becomes a powerful wetting agent (it... -
Structure and Dynamics of the Liquid-Solid Transition in amphiphiles with hyd...
An unusual series of amphiphilic molecules that form surface films on water have been investigated using a combination of Langmuir¿Blodget, ellispometric, and non-linear laser... -
Competitive adsorption in hydrophobin / protein mixtures at the solid-solutio...
Hydrophobins are secreted fungal proteins in the form of small lipopetide biosurfactants. They are strongly surface active and self-assemble at interfaces and in solution. This... -
Probing perfume surface delivery / retention rates in-situ
This proposal is part of a funded (CASE) project, aimed at understanding the delivery of benefit actives (perfumes) to interfaces and the development of new self-assembled... -
Multilayer formation at the air-water interface in polyamine / surfactant mix...
The spontaneous formation of multilayer structures at interfaces by surfactant self-assembly is emerging as an important and more common structural signature associated with a...
