Properties of nanoparticles are significantly different from their bulk counterparts, including their biological and toxic activity. The properties of silver nanoparticles governing their toxicological effects are summarized. These basic characteristics can be used as descriptors for modelling the toxic properties of nanoparticles.

A method for synthesizing a photochromic ligand and using it as a structural element in a new nanodimensional hybrid construction in which CdSe quantum dots are covalently bonded to a spiropyran...

Methods for preparation of 5′-substituted spiropyrans, their chemical properties, and the effects of various factors on the relative stabilities of the spiropyrans and their isomeric merocyanine forms are examined, reviewed, and discussed.
