It has been shown that gel particles are able to stabilize the oil-water interface and forming emulsions ( the so called "Pickering emulsions"). It has also been shown that...

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

We will study the temperature dependence of carbon nanotubes in solutions using small angle neutron scattering, to investigate in particular the rebundling when the free energy...

Water is intimately entwined structurally with DNA. Depending on its hydration state, DNA can form several forms: A, B, C, D and Z. In addition water bound in the grooves of the...

With this proposal we want to study the (deuterated) hydration shell of facetted iron oxide nanoparticles (IONPs). IONP–water interfaces are of great importance for biomedical...

Lipopeptide surfactants are a group of interesting biosurfactants due to their natural origin and their high effectiveness at reducing interfacial tension. However, there is a...

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...

Following our previous study of adsorption of globular lysozyme and BSA, we continue to explore how another globular protein hydrophobin adsorbs at the oil/water interface by...

Many proteins exhibit a lag in lowering the surface tension at the air-water interface. The origin of this lag is not well understood either experimentally or theoretically. The...

Manipulating nanoparticles in liquids is crucial for their scalable implementation in future technologies. For example, such liquids can be used like paint to create uniform...

Through a combination of small angle neutron scattering, ion-beam analysis and ellipsometry we have recently demonstrated that in organic photovoltaic devices (OPVs) the...

Increased environmental pressures and awareness is promoting a major drive towards an increased use of biosurfactants to produce more biosustainable and biodegradable consumer...

In recent years nanogels show great potential as drug delivery systems. Especially dermal drug administration which is non-invasive, helps to avoid the first-pass effect with...

The aim of this proposal is the application of the scaling model for the adsorption of proteins at the oil-water interface. The adsorbed amount for a series of oils as a...

Nonionic surfactants usually do not show affinity to proteins and they work via competitive surface and interfacial processes in a binary mixture with protein. However, we show...

Manipulating nanoparticles in liquids is crucial for their scalable implementation in future technologies. For example, such liquids can be used like paint to create uniform...

Short peptide sequences consisting of hydrophobic and hydrophilic amino acid units are capable of self-assembly, leading interfacial adsorption and solution nano-aggregation....

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...

Adsorption of a charged polyelectrolyte onto an oppositely charged substrate is important for the understanding of many natural molecular events as well as for the development...

Peptide-functionalized nanoparticle (NP) aggregates have significant potential as biosensors (for specific enzymes) due to their high sensitivity, modular design and simple...
