Metal-organic frameworks (MOFs) comprising amines on the organic linker can be used for cell targeting. In particular, primary amine groups represent one of the most versatile chemical moieties for conjugation to biologically relevant molecules, including antibodies and enzymes. Different chemical conjugation schemes can be used to conjugate biological molecules to the amino functionality on the organic linker. For example, carbodiimide chemistry can be used to link a primary amine to available carboxyl groups on the protein. For example, sulfhydryl crosslinking chemistry can be used via Traut's reagent scheme. As a demonstration of the invention, the ability of EpCAM antibody-targeted MOFs to bind to a human epithelial cell line (A549), a common target for imaging studies, was confirmed with confocal microscopy.

Described herein are heterogeneous catalysts for removing impurities, such as halogen oxyanions (e.g., ClO.sub.4.sup.− and ClO.sub.3.sup.−), from a fluid, the catalyst can comprise: an oxygen atom transfer (OAT) transition metal, a Group VIII metal, and a support, where the transition metal, and the Group VIII metal can be in physical communication with the support either directly or indirectly through each other, whereby the catalyst can chemically remove impurities from the fluid. Certain embodiments provide catalysts that further comprise nitrogen donor ligand(s). Accordingly, such catalysts that comprise the OAT transition metal in the form of a complex with one or more nitrogen donor ligands have enhanced efficiency in reducing halogen oxyanion (e.g., ClO.sub.4.sup.−) to Cl.sup.−. Also described are methods or kits for making the catalysts and methods or reactor for the treatment of a fluid utilizing the catalyst.

Low molecular weight, high Tg resins, with applications including tire additives and adhesives. An oligomer is obtained by ring opening metathesis polymerization (ROMP) of a sterically encumbered cyclic monomer with an olefinic chain transfer agent. The sterically encumbered cyclic monomer and the olefinic chain transfer agent are present in the polymerization at a molar ratio of from 2:1 to about 40:1. Also, methods for making the oligomer by ROMP.
