A fluorescent chemical sensor based upon a core/shell architecture of silica nanoparticles (see figure) is introduced. By covalent attachment of organic reference dyes within the core and sensor dyes in the outer shell, optimal sensor architectures can be realized. This paves the way for the development of highly functional particles with catalytic or synthetic abilities.
