Plastic bags are used as containers for storage of donated blood. These bags are typically made out of PVC plasticized with dialkylphthalates (e.g. DEHP), which migrates into...

Bilayer lipid membranes and their interactions with the integral or peripheral proteins serve as one of the key mechanism in various cellular functions like communication, cell...

N-acyl amino acids are promising anionic amphiphilic molecules, which consist of a linear aliphatic chain (hydrophobic tail) and an amino-acid residue (polar head). Although...

The air/water interface works as the simplest model for screening protein adsorption. Many previous studies have been made to examine protein adsorption at this interface....

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...

Tolaasin is a lipodepsipeptide (lipo = hydrophobic side chain, depsipeptide is an amino acid ring closed in a particular way) produced by strains of Pseudomonas tolaasii, and it...

Proteins are important in many applications ranging from the stabilisation of emulsions (oil-water interface) to foams (air-water interface). Understanding the relationship...

An number of potential drugs, including steroidal drugs are extremely water insoluble, limiting their commercialisation as medicines. Solubilisation of drug in surfactant...

It is the aim of the proposal is to perform neutron reflectivity (NR) studies combined with contrast variation to determine the structure of phospholipid monolayers on a...

Recently we have exploited non-equilibrium effects in the preparation of super-efficient polyelectrolyte/surfactant films at the air/water interface spread from the dissociation...

Amino acid based surfactants have been known for many years but so far few detailed studies have been carried out on their properties. We are using amino acids extracted from...

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...

Surface-active molecules with water-loving and water-hating parts have been found to contribute substantially to the man-made urban aerosol load originating from cooking...

We have now established that multilayering at the air-water interface is a widespread phenomenon brought about by multivalent ions, whether polyelectrolyte, oligoelectrolyte or...

Cardiolipin (CL) is a structurally unique dimeric phospholipid localized in the inner mitochondrial membrane, which is known to provide essential structural and functional...

The global increase of bacterial resistance to antibiotics has led to increasing interest in research focusing on the development and characterization of new antimicrobial...

A Unilever proprietary technology has been shown to inhibit biofilm growth and development, and is also found to possess antimicrobial activity, effective both as a...

Skin becomes a target of drug delivery because the transdermal routes are non-invasive, can be self-administrated, improve patient compliance and can provide release for long...

In this work, we propose to exploit the unique capability of neutron reflection (NR) to study the structural changes of multi-component lipid monolayer models mimicking...

Single molecule thin films of various surface-active species are found on the surface of water bodies from the sea down to microscopic spray droplets. These films affect the...
