Loading of atorvastatin and linezolid in β-cyclodextrin-conjugated cadmium selenide/silica nanoparticles: A spectroscopic study.

The preparation of β-cyclodextrin-conjugated cadmium selenide-silica nanoparticles, the loading of two drugs viz., Atorvastatin and linezolid in the cyclodextrin cavity, and the fluorescence energy transfer between CdSe/SiO2 nanoparticles and the drugs encapsulated in the cyclodextrin cavity are reported in this paper. IR spectroscopy, X-ray diffractometry, transmission electron microscopy, and particle size analysis by light-scattering experiment were used as the tools of characterizing the size and the crystal system of the nanoparticles.

A Highly Selective Fluorescent Sensor for Pb(2+) Based on a Modified β-Cyclodextrin.

A modified cyclodextrin is synthesized as an anthracene derivative of 6-deoxy- 6-aminoethylamino-β-cyclodextrin and characterized using IR, NMR, and mass spectral techniques. The compound acts as a sensor of Pb(2+) ions in a pool of several metal ions, by enhancement of fluorescence. The absorption spectrum does not show significant changes on the addition of metal ions.
