Nanoparticles at work: High‐contrast tumorimaging of mice was performed by usingcopolymers with hydrophobic and hydrophilic polymer brushes that form cross‐linked assemblies and show a highly stable core surface in aqueous media (see picture). Cyclic RGD peptides and glucosamine moieties were localized on the surface of the assemblies and acted as targeting agents (TA) that enhanced the accumulation

Efficient routes to the synthesis of norbornadiene-tethered nitrones have been developed, and their intramolecular 1,3-dipolar cycloadditions were studied. The cycloadditions occurred in moderate to good yields for a variety of substrates and were found to be highly regio- and stereoselective, giving single regio- and stereoisomers in most cases.
