The present application relates to a chemical compound comprising an aromatic core, or a carbocyclic, non-aromatic, core, wherein the aromatic core is a benzene ring or a biphenyl; the carbocyclic, non-aromatic core is a 5 to 7 membered ring. The core has covalently attached thereto: at least two anchoring groups, each anchoring group comprising an activated silane group, wherein the anchoring groups have the following general formula -A-(CH.sub.2)nSiY3 wherein A is a covalent bond or O, “n” is an integer from 1 to 3, and Y is independently a methoxy group or an ethoxy group; and at least one hydrophilic group extending from the core, the hydrophilic group comprising one or more hydrophilic polymer residues with a molecular composition of (aO+bN)/(cC+dS+eSi+fP)>0.3 where a, b, c, d, e and f are the mol percentage of oxygen (O), nitrogen (N), carbon (C), sulfur (S), silicon (Si) and phosphorus (P), respectively; wherein the hydrophilic polymer residue(s) is(are) selected, independently of each other if more than one hydrophilic group is present, from —(O—CH.sub.2—CH.sub.2).sub.m—OX, wherein X is CH.sub.3 or H, and “m” is an integer from 6 to 25; and the number of hydrophilic groups extending from the core is from one to the number of ring structures in the core. The present invention also relates to compositions comprising the chemical compound and nanostructures comprising residues of the chemical compound as well as the use of such nanostructures. Furthermore, the invention relates to methods for obtaining the chemical compounds and the nanostructures.
