    摘要: This present disclosure relates to pharmaceutical compositions for treating tumors using a polymeric micelle encapsulating an anti-tumor drug. The polymeric micelle comprises block copolymers comprising at least one hydrophilic block, at least one hydrophobic block, and at least one zwitterion. The present disclosure also relates to methods of enhancing the solubility of such drugs, methods of increasing the blood circulating time of such drugs, and methods of delivering such drugs to one or more solid tumors.

    摘要: A method of making a porous biodegradable polymer is disclosed, which comprises (a) placing a biodegradable polymer and a solvent in a chamber; (b) adding a supercritical fluid to the chamber and maintaining the chamber at a predetermined temperature for a sufficient period of time to allow the supercritical fluid to dissolve into the biodegradable polymer with the help of the solvent; and (c) venting the supercritical fluid and the solvent by reducing the pressure in the chamber, thereby obtaining a porous biodegradable polymer.

    摘要: The present invention relates to crosslinking of porous materials made of biodegradable polymers. The method comprises: (a) placing a porous biodegradable polymer in a chamber; (b) introducing a supercritical fluid containing a crosslinking agent into the chamber to effect crosslinking of the porous biodegradable polymer; and optionally (c) introducing a pure supercritical into the chamber to wash the crosslinked polymer until the crosslinking agent is substantially removed from the polymer.
