    摘要: The present invention is related to a composition of PI3K inhibitor, comprising: 0.01˜10 mg of PI3K inhibitor; 10˜500 mg of poly(lactic-co-glycolic acid) (PLGA) which is encapsulated onto the surface of the PI3K inhibitor and the surface is non-modified by a modifier; and the composition has a size of 10˜1000 nm. Thereby, an excellent effect on suppressing the growth of tumor cells will be achieved by the encapsulation of PI3K inhibitor into PLGA nanomaterials without any modifier on its surface, the optimization of a ratio of PI3K inhibitor to PLGA, and the accordingly slow release of the composition.

    摘要: The present invention relates to a process for preparing water-soluble and dispersed iron oxide (Fe3O4) nanoparticles and application thereof, characterized in which two-stage additions of protective agent and chemical co-precipitation are employed in the process. In the first stage, Fe3O4 nanoparticles are obtained using absorbent-reactant coexistence technology. In the second stage, proper amount of adherent is added to cover the nanoparticle surface entirely. The resulting water-soluble and dispersed Fe3O4 nanoparticles can easily bind with thiols or biomolecules, such as nucleic acid and peptide. The Fe3O4 nanoparticles of the present invention may be used as magnetic resonance imaging contrast agent and used in magnetic guiding related biomolecular technologies for clinical testing, diagnosis and treatment.
