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 Pb2+ ions in a pool of several metal ions, by enhancement of fluorescence. The absorption spectrum does not show significant changes on the addition of(More)
We report the loading of drugs on aminoethylaminodextran-coated iron oxide nanoparticles, their superparamagnetic behavior, loading of drugs on them, and the β-cyclodextrin-complex formation of the drugs on the surface of the nanoparticles. The magnetic behavior is studied using vibrating sample magnetometry and X-ray photoelectron spectroscopy is used to(More)
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,(More)
Ion-induced change in fluorescence is a straight-forward method for detection of toxic metal ions showing immediate response. Cadmium ions are toxic to the environment. We report in this paper a piperidine-4-one-based fluorescent chemosensor of Cd2+ ions, designed and synthesized by a simple method. The compound is characterized using infra-red (IR) and 1(More)
