Core/shell nanoparticles suitable for (F) RET-assays

摘要

The present invention relates to luminescent inorganic nanoparticles comprising (a) a core made from a first metal salt or oxide being surrounded by (b) a shell made from a second metal salt or oxide being luminescent and having non-semiconductor properties. <??>These particles can be advantageously used in (fluorescence) resonance energy transfer ((F)RET)-based bioassays in view of their higher (F)RET efficiency.
