An outline of some of the key biological functions and coordination chemistry of carbohydrates is given, along with an introduction to bioconjugation and molecular imaging. Technetium coordination chemistry and the subset of this involving bioconjugates are discussed before moving into the focus of the article: glycoconjugates of Tc-99m(v) and the more recently developed [Tc-99m(I)(CO)(3)](+). Significant work in the last decade has featured the very attractive [Tc-99m(CO)(3)](+) core, and the ligand sets designed for this core are discussed in detail.}, keywords = {ANTITUMOR-ACTIVITY, BIFUNCTIONAL CHELATORS, BIOLOGICAL EVALUATION, D-GLUCOSE, IN-VITRO, ISOSTRUCTURAL RE, METAL-COMPLEXES, STRUCTURAL-CHARACTERIZATION, TC-99M COMPLEXES, TRICARBONYL COMPLEXES}, isbn = {1359-7345}, url = {://000260407400002}, author = {Bowen, M.

A detailed biodistribution study of two derivatized hyperbranched polyglycerols of different molecular weights derivatized with hydrophobic groups and short poly(ethylene glycol) chains is reported in this article. In mice, these materials are nontoxic with circulation half-lives as high as 31 h, controllable by manipulating the molecular weight and the degree of PEG derivatization. Organ accumulation is low, presumably due to the "pegylation" effect. Thermal degradation and hydrolysis data suggest that these polymers are highly stable with a long shelf life, a major advantage for a pharmaceutical product. Degradation under acidic conditions has been observed for these polymers.}, keywords = {ALBUMIN, BIOLOGICAL EVALUATION, DENDRIMERS, IMMUNOGENICITY, IN-VIVO, LIPOSOMES, MOLECULAR-WEIGHT, POLYETHYLENE-GLYCOL DEGRADATION, POLYMERS, STARCH}, isbn = {1043-1802}, url = {://000261001800018}, author = {Kainthan, R.
