A short peptide, composed of 12 amino acids (EFVFVAHAVPVM), presenting a strongly hydrophobic character, was recently isolated from Lactobacillus gasseri supernatant (AMP12)....

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

This proposal continues our investigations into polyelectrolyte-surfactant films at the air-solution interface. Using mixtures of cationic and anionic surfactants (CTAB/SDS) we...

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...

Protamines are cationic antimicrobial peptides found commonly in the sperm cells of fish such as herring and salmon that are particularly active against food-borne Gram-negative...

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...

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...

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...

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...

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...

Biological membrane mimics are a bottle neck in biophysical studies today. The need to develop advanced models that actually represent the properties of specific cellular...

Proximity effects associated with magnetic impurities embedded in paramagnetic Pd have been known to produced so-called giant moments. It has been demonstrated that confining Fe...

Marine biofouling compromises function and reliability of marine equipment, causing considerable economic and environmental damage. Biocides for fouling prevention are...

The yeast Candida glabrata is becoming an increasing cause of infections. We have developed RNA interference tools that allow us to study the virulence and resistance mechanisms...

The lung surfactant is a film coating the alveolus of the lung. We want to characterize the structure of this film at the air-water interface at a molecular level. This will...

Cyclic peptide-polymer nanotubes can readily self-assembly into long nanotubes, and are being extensively studied for drug delivery applications. As such, understanding how...

The fabrication of composite coatings based on silica with well defined physical properties represents a promising new approach to fine-tune mechanical, optical, electronic, and...
