Abstract
Described are methods for modifying a substrate by exposing the substrate to a densified fluid. The substrate may be a polymer or a metal alloy, and the densified fluid may be carbon dioxide. Uses of such substrate modification include impregnation of the substrate with one or more drugs, impregnation of microcellular particles, and formation of microcellular compositions.
