Abstract
A substrate is modified 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, surface modification of the substrate, and formation of microcellular compositions.
