The present invention provides an organosilicon nanocapsule, which includes:a nanoscale core A, which includes:at least one particle including at least one oxide or mixed oxide, KA-O, of at least one metal or semimetal selected from the group including main groups 2 to 6 of the Periodic Table, transition groups 1 to 8 of the Periodic Table, lanthanides, and mixtures thereof; andan organosilicon shell B, which includes:at least one organosilicon compound having the formula (Ia):wherein R is a linear, branched, cyclic or substituted alkyl group having from 1 to 50 carbon atoms;wherein x is a number from 0 to 20;wherein remaining free valences of Si are each independently (KA-O)-, SiO- or -Z;wherein remaining free valences of Si' are each independently (KA-O)-, SiO-, -R, or -Z;wherein the Z's are each independently hydroxyl or alkoxy radicals; andwherein each Si and Si' in the shell B have not more than one R group attatched thereto.
