Abstract

The invention relates to essentially water-insoluble amphiphilic particles or molecules having predominantly hydrophilic and predominantly hydrophobic domains distributed anisotropically over their surface and a particle size ranging from 1 nm to 100 &mgr;m, consisting of antagonistic partial amounts of particles or molecules, which in each case have predominantly hydrophilic or predominantly hydrophobic domains, the partial amounts of the particles or molecules being agglomerated or associated over polar interactions or hydrogen bonds, as well as to a method for producing these particles or molecules and to the selective use of the particles or molecules.
