Transporting gold across physical boundaries

Abstract:
Achieving the desired effect is often only a question of the right place and the right moment - and this also applies to drugs. In order to be transported in the bloodstream, they need to be water-soluble. However, in order to get past cell membranes, they have to be fat-soluble. Scientists at the Max Planck Institute of Colloids and Interfaces have now developed a method with which they can channel nanoparticles originating from gold atoms from a water solution into an oil. The water and oil system serves as a model for the boundary between the bloodstream and tissue. The researchers are able to overcome this boundary in a targeted manner, as they are able to coat the particles with a polymer whose solubility they can influence ("Stimuli-Responsive Reversible Transport of Nanoparticles Across Water/Oil Interfaces")
