A new method has been investigated for the functionalization of gold nanoparticles with DNA. Silica-coated nanoparticles functionalized with a maleimide have been prepared. These particles are designed to react with modified DNA containing a diene functionality at one end of the molecule. The result would be the formation of a more stable attachment of the DNA to the particle through a Diels-Alder reaction. This covalent attachment would not be susceptible to ligand exchanges, which are known to occur in the conventional DNA functionalization of gold nanoparticles. Copyright Taylor & Francis, Inc.

A novel thermoresponsive snaptop for stimulated cargo release from superparamagnetic iron oxide core - mesoporous silica shell nanoparticles based on a [2 + 4] cycloreversion reaction (retro-Diels Alder reaction) is presented. The non-invasive external actuation through alternating magnetic fields makes this material a promising candidate for future applications in externally triggered drug delivery.

Process for preparing unsaturated imidoalkoxysilanes
-
Page/Page column 4/2, (2008/06/13)
A process is provided for preparing unsaturated imidoalkoxysilane which comprises imidating substantially water-free Diels-Alder protected unsaturated N-substituted cyclic imide with aminosilane to provide Diels-Alder protected unsaturated imidoalkoxysilane without the use of chemical desiccants. The Diels-Alder protected unsaturated imidoalkoxysilane produced is then deprotected to provide unsaturated imidoalkoxysilane and the Diels-Alder protecting diene is regenerated to the process. A Diels-Alder intermediate is also provided.
