    • The present invention relates to the preparation of hydrophilic nanoparticles and in particular hydrophilic nanoparticles that are biocompatible. Free radical monovinyl-divinyl monomer copolymerization/cross-linking reactions of water-soluble, monovinyl N-vinyl-2-pyrrolidone (NVP) with a bi-unsaturated divinyl, comonomer (poly{ethylene glycol}dimethacrylate) (PEGDMA), has been found to yield hydrophilic nanoparticles (NPs). These nanoparticles are built from three-dimensional nanopolymer networks. In the polymers' synthesis the composition of the monomers, and the total monomer concentration were varied. The characteristics of copolymers were determined by nuclear magnetic resonance spectroscopy (NMR), Fourier transform infrared (FTIR) and elemental analysis. Particle size and morphology of nanoparticles were confirmed by dynamic light scattering (DLS), transmission electron microscope (TEM) and scanning electron microscope (SEM) methods. In the present invention hydrophilic polymers can be used in micellar polymerization to create hydrophilic nanoparticles.
    • 本发明涉及亲水性纳米颗粒的制备,特别是生物相容的亲水性纳米颗粒。 已经将水溶性单乙烯基N-乙烯基-2-吡咯烷酮(NVP)与双不饱和二乙烯基共聚单体(聚{乙二醇}二甲基丙烯酸酯)(PEGDMA))的自由基单乙烯基 - 二乙烯基单体共聚/交联反应 发现产生亲水性纳米颗粒(NP)。 这些纳米颗粒由三维纳米聚合物网络构建。 在聚合物的合成中,单体的组成和总单体浓度是变化的。 通过核磁共振光谱(NMR),傅立叶变换红外(FTIR)和元素分析测定共聚物的特性。 通过动态光散射(DLS),透射电子显微镜(TEM)和扫描电子显微镜(SEM)方法证实了纳米颗粒的粒径和形貌。 在本发明中,亲水性聚合物可用于胶束聚合以产生亲水性纳米颗粒。
