Abstract: The present invention generally relates to foams and, in particular, to foams for applications such as drug delivery, and particles that are made from such foams. One aspect relates to foams or particles containing pharmaceutically active agents. The foam may comprise a pharmaceutically acceptable polymeric carrier. In some cases, the foam or particle has an unexpectedly high specific surface area. A high specific surface area may, in some cases, facilitate delivery or release of the pharmaceutically active agent when the foam or particles made from the foam (e.g., by milling) are administered to a subject. The foam may also exhibit a relatively high loading of the pharmaceutically active agent. In some cases, the foam may be a microcellular foam. In one set of embodiments, the foam is created using a supercritical fluid, such as supercritical C02.
