Equation, which may explain the repulsive force water from the oil

For the first time scientists have deduced an equation which involves hydrophobic interactions between the molecules. These interactions may explain why oil and water can not mix, but also show how to construct proteins and biological membranes that hold together.

Using the light-sensitive surfactant - a molecule similar in structure to the usual soap, and similar to the fats and lipids, the researchers developed. innovative technology. to measure or change of power between the layers of molecules in water, using beams of ultraviolet radiation or visible light. As a result, they received a general equation that applies to more complex systems, such as the cell membrane or protein.

They used a highly sensitive instrument - an apparatus for measuring the sensitivity of the surface and hydrophobic forces at the molecular level. Now this technique is standard in the 1970s, it began to explore Israelachvili and his colleagues. ... This theory was developed more than 100 years ago, ...
... There was not a proven theory to explain these specific hydrophobic interactions. This behavior, as we know it exists and is of crucial importance in everyday life ...




Hydrophobic and hydrophilic interactions are central to the disciplines of chemistry, physics and biology, which are basic to modern developments in the manufacture of detergents to pharmaceuticals and the new biotechnologies. The new equation will be used in water filtration technology, separation membranes, biomedical research, methods of gene therapy, production of biofuels, food chemistry.
The spread of viruses and diseases in the human body is directly related to the hydrophobic properties at the cellular level. One of the problems associated with chemotherapy for cancer treatment is the possibility of direct drug delivery to cancer cells, rather than introducing it into the whole body.
Israelachvili and his colleagues have provided their discovery, conducting a study in which they tried to understand and find ways to treat diseases.

... I was looking for the keys to this interaction, for 30 years. We are delighted with the results, but it was a long time before carefully chosen steps we have achieved this result, ...
