    • A method produces polymer nanoparticles. Polymer solution is sprayed through a nozzle toward a collector. An electric field is created at the nozzle, such as by a voltage is applied to the nozzle to create the electric field. The voltage applied to the nozzle is from ˜10 (Kilovolt) to ˜30 (Kilovolt), distance from nozzle tip to collector is from ˜1 (centimeter) to ˜10 (centimeter) and the polymer concentration from ˜0.01% to ˜0.5% w/w. Preferably a grounded liquid collectors is used. The invention provides biocompatible monodisperse polymer nanoparticles having a size of less than ˜300 nm, preferably less than ˜150 nm. Payloads can be associated, and maintain efficacy, including more than one payload such as therapeutic agents and diagnostic agents on the same particles. Preferred particles are poly(methyl methacrylate) (PMMA-COOH) or acrylate analogues.
    • 一种方法产生聚合物纳米颗粒。 聚合物溶液通过喷嘴朝向收集器喷射。 在喷嘴处产生电场,例如通过向喷嘴施加电压以产生电场。 施加到喷嘴的电压为〜10(千伏)〜〜30(千伏),从喷嘴尖到收集器的距离为〜(厘米)〜〜10厘米,聚合物浓度为〜0.01〜 %w / w。 优选使用接地液体收集器。 本发明提供具有小于〜300nm,优选小于〜150nm的尺寸的生物相容性单分散聚合物纳米颗粒。 有效载荷可以相关联,并保持功效,包括多个有效载荷,如治疗剂和诊断剂在同一颗粒上。 优选的颗粒是聚(甲基丙烯酸甲酯)(PMMA-COOH)或丙烯酸酯类似物。
