Organic cadmium selenide

Nanoparticles such as those of the heavy metals, like cadmium selenide, cadmium sulfide, lead sulfide, and cadmium telluride are potentially toxic [14,15]. The possible mechanisms by which nanoparticles cause toxicity inside cells are schematically shown in Fig. 2. They need to be coated or capped with low toxicity or nontoxic organic molecules or polymers (e.g., PEG) or with inorganic layers (e.g., ZnS and silica) for most of the biomedical applications. In fact, many biomedical imaging and detection applications of QDs encapsulated by complex molecules do not exhibit noticeable toxic effects [16]. One report shows that the tumor cells labeled with QDs survived in circulation and extravasated into tissues... 

The photocurrent doubling has been verified for the photo-oxidation at the ZnO photoelectrode of a large variety of organic and also some inorganic spedes . Subsequently, similar observations have been made for other n-type semiconducting photoanodes cadmium sulfide cadmium selenide strontium titanate and titanium dioxide Rather in contrast with the behaviour of other above mentioned photoelectrodes (i.e., ZnO, CdS and CdSe), in the case of the Ti02 photoanode the multiplication of the photocurrent appears to be more effective in acidic than in alkaline solu-tions ... 

Samarium selenides. Reductive cleavage of ArSeSeAr by samarium is catalyzed by a great number of metal halides bismuth(III) chloride, cadmium chloride, chromium(IIl) chloride, cobalt(II) chloride, potassium iodide, and titanium(lV) chloride. The resulting samarium arylselenides readily react with various organic halides.
