    • This invention relates to a novel process of manufacture of nanoparticles of substantially water insoluble materials from emulsions. The emulsions have the ability to form a single liquid phase upon dilution of the external phase, instantly producing dispersible solid nanoparticles. The formed nanoparticles have average diameter of about 10 to 200 nm and are suitable for drug delivery and targeting of water insoluble therapeutic or diagnostic agents. Examples of such agents are methotrexate, progesterone, testosterone, prednisolone, and ibuprofen. Such agents can be used in a wide range of therapeutic and diagnostic treatments including treatment for cancer, hormonal therapy, and pain management.
    • 本发明涉及从乳液制造基本上不溶于水的材料的纳米颗粒的新方法。 该乳液能够在外相稀释时形成单一液相,立即产生可分散的固体纳米颗粒。 形成的纳米颗粒具有约10至200nm的平均直径,并且适用于药物递送和水不溶性治疗剂或诊断剂的靶向。 这些试剂的实例是甲氨蝶呤,孕酮,睾酮,泼尼松龙和布洛芬。 这些药物可用于广泛的治疗和诊断治疗,包括治疗癌症,激素治疗和疼痛治疗。
