金脂结合物

This new conjugate from Avanti consists of an Aurora® gold cluster capped with triphenylphosphine ligands and a single diglyceride ligand. Fifty-five gold atom nanoparticles, first described by Schmid, are fascinating structures that are commonly used for contrast agents in various imaging applications. Ideally this particle, unlike larger colloidal style particles, is less intrusive to the target application and behaves like an organic entity instead of a foreign metallic probe. They also are a great generic platform for bottom up synthesis of novel, gold-centered nanostructures due to the ease and completeness of ligand exchange reactions. This complex is readily visible under TEM and can also be viewed in optical microscopes if further processed using a silver development procedure.
