摘要:
An improved polymer delivery system is described which provides polymeric microparticle compositions and porous microparticles formed therefrom. Pore size, pore architecture as well as particle size are also controllable. In some embodiments, both the polymeric microparticle compositions and porous microparticles formed therefrom encapsulate at least one substance, such as a biologic substance (one having biologic activity and/or compatible with a biologic system). The encapsulation occurs prior to polymerization. The amount of substance that is encapsulated may be controlled by the described methods. Said methods do not emply organic solvents. As such, the fabrication occurs in a solvent-free system.
