我们报告了一种新型脂质-聚合物混合纳米颗粒(NP)的工程设计,作为一个强大的药物递送平台,具有高药物包封率,可调和持续的药物释放曲线,优异的血清稳定性,以及细胞或组织的差异靶向潜力。NP由三种不同的功能组分组成:i)疏水性聚合物核,其中可包封水溶性差的药物; ii)具有抗生物污染性质的亲水性聚合物壳,以增强NP稳定性和体循环半衰期;和iii)在核和壳的界面处的脂质单层,其充当分子栅栏以促进药物保留在聚合物核内,从而提高药物包封率,提高载药量,控制药物释放。NP是通过一步纳米沉淀法以可重复和可预测的方式通过自组装制备的,使其具有潜在的放大潜力
We report the engineering of a novel lipid-polymer hybrid nanoparticle (NP) as a robust drug delivery platform, with high drug encapsulation yield, tunable and sustained drug release profile, excellent serum stability, and potential for differential targeting of cells or tissues. The NP is comprised of three distinct functional components: i) a hydrophobic polymeric core where poorly water-soluble drugs can be encapsulated; ii) a hydrophilic polymeric shell with anti-biofouling properties to enhance NP stability and systemic circulation half-life; and iii) a lipid monolayer at the interface of the core and the shell that acts as a molecular fence to promote drug retention inside the polymeric core, thereby enhancing drug encapsulation efficiency, increasing drug loading yield, and controlling drug release. The NP is prepared by self-assembly through a single-step nanoprecipitation method in a reproducible and predictable manner, making it potentially suitable for scale-up
