Abstract
Compact polymer/metal composite particles, sized or unsized, in which the metal is in the form of crystallites encapsulated in a polymer matrix. The composite particles may be prepared by introducing a metal complex into a swollen polymer in an organic liquid which is a solvent for the metal complex, followed by thermal decomposition of the metal complex and removal of the swelling organic liquid. The composite particles may be used in biological applications.
