Abstract:
1. Surface-modified nanoparticles whose surface is covered completely or near-completely with (A) modifying groups which are attached covalently to the surface via at least one linking functional group (a) and contain at least one inert spacer group (b) and contain at least one reactive functional group (c) which is connected via the group (b) to the group (a) and is inert toward the reactive functional groups of the surface to be modified, (B) modifying groups which are attached covalently to the surface via at least one linking functional group (a) and contain at least one inert group (d) attached to the surface via group (a) having a smaller hydrodynamic volume V (C) modifying groups which are attached covalently to the surface via at least one linking functional group (a) which contains at least one silicon atom, contain at least one inert group (e) attached to the surface via group (a), and have a smaller hydrodynamic volume V
