Implantable swellable bio-resorbable polymer

An injectable biomaterial containing a non-aqueous solvent suitable for injection to a human being and nanoparticles made of a polymer that is insoluble in water and insoluble in the non-aqueous solvent, in which the nanoparticles are loaded with a drug or a biological agent. The injectable biomaterial is suitable for occluding normal or malformative blood vessels or non-circulating cavities, or for necrosing tumors.

Injectable biomaterial

A process for the chromatographic interseparation of rhodium in admixture with at least one base metal from a feed solution includes complexes of these metals. The process includes contacting the solution with at least one chromatographic medium, and eluting one or more fractions such that at least one fraction includes rhodium complex substantially free from base metal contamination. The at least one chromatography medium includes a support functionalized with substituted amine groups which further include at least one hydrophilic group. Other platinum group metals can also be separated, both from one another and from base metals.
