A simple and general procedure is described for the development of fluorescence resonance energy transfer (FRET) systems by the co-immobilization in a sol-gel matrix of photoluminescent quantum dots with a given dye "acceptor".

Inductively coupled plasma mass spectrometry (ICPMS) measurements are used to study with unprecedented accuracy and precision the formation and stoichiometry of the nanoparticle core and shell of CdSe quantum dots (QDs).

A novel molecularly imprinted polymer (MIP) of high interest for room temperature phosphorescence (RTP) sensing systems is described; the synthesized MIP contains iodine as internal heavy atom in the polymeric structure and its applicability for RTP sensing of fluoranthene at microg L(-1) levels is demonstrated.
