This invention relates to SPPs, spherical nanocrystalline composite particles or crystalline SPPs of biologically active proteins or compositions, including formulations, comprising such SPPs, spherical nanocrystalline composite particles or crystalline SPPs. More particularly, methods are provided for the production of SPPs, spherical nanocrystalline composite particles or crystalline SPPs of high concentrations of biologically active proteins, and for the preparation of stabilized SPPs, spherical nanocrystalline composite particles or crystalline SPPs for use alone, or in dry or slurry compositions. This invention also relates to methods for stabilization, storage and delivery of biologically active proteins using SPPs, spherical nanocrystalline composite particles or crystalline SPPs. The present invention further relates to methods using SPPs, spherical nanocrystalline composite particles or crystalline SPPs, or compositions or formulations comprising such SPPs, spherical nanocrystalline composite particles or crystalline SPPs, for biomedical applications, including biological delivery to humans and animals.
