Objective To prepare docetaxel(DTX)-loaded active breast cancer-targeted pH-responsive nanoparticles and to determine its chemo-physical properties,drug loading and releasing characteristics,and targeting ability and cytotoxity against MCF-7cells.Methods The nanoparticles were synthesized by nanoprecipitation method and surface modification based on polydopamine(PDA).The morphology,size and zeta potential,and surface modification of the nanoparticles were characterized by transmission electron microscopy(TE...
[Acad J Sec Mil Med Univ,2017,38(6):707-714]近年来肿瘤纳米药物被广泛研究,其中连接主动靶向配体的纳米药物载体是一种可以实现精准靶向的给药系统[1]。这种给药系统能够在肿瘤病灶部位有效富集,通过靶向配体介导的内吞作用进入细胞,并通过控制药物释放实现对肿瘤细胞的杀?
