项目摘要
Surface modification strategies were carefully monitored to achieve drug nanoparticles with enhanced drug delivery efficiency (Chem. Lett. 2021, 50, 1555-1558; Mol. Crys. Liq. Crys., in press 2022). For the preparation of liposomal membrane modified drug nanoparticles, the coating on the drug nanoparticle surface was achieved by the sequential extrusion of membrane vesicle with the SN-38 drug nanoparticles model system. The modified drug nanoparticles were obtained in a slightly larger size, with narrow size distribution as confirmed by DLS. The liposomal layer on the nanoparticle’s surface was successfully confirmed by fluorescence and SEM images. In addition to the enhanced dispersion stability in the physiological environment, we have also shown that the liposomal membrane layer can be further modified to provide drug nanoparticles with specific cancer targeting and fluorescence imaging capability. The optimized protocol will be employed for the modification of drug nanoparticles with the liposomal membrane derived from natural sources such as red blood cells, white blood cells, and cancer cells.
仔细监测表面改性策略以获得具有增强的药物递送效率的药物纳米颗粒(Chem.Lett. 2021,50,1555-1558; Mol.哭泣。液态哭泣,2022年出版)。以SN-38药物纳米粒为模型体系,通过连续挤出膜囊泡的方法,实现了脂质体膜修饰药物纳米粒表面的包覆。修饰的药物纳米颗粒以稍大的尺寸获得,具有窄的尺寸分布,如DLS所证实的。通过荧光和SEM图像成功地证实了纳米颗粒表面上的脂质体层。除了在生理环境中增强的分散稳定性之外,我们还表明可以进一步修饰脂质体膜层以提供具有特异性癌症靶向和荧光成像能力的药物纳米颗粒。优化的方案将用于修饰药物纳米粒与脂质体膜衍生自天然来源,如红细胞,白色血细胞,和癌细胞。
