Renally cleared zwitterionic nanocarriers (H-Dots) are composed of ε-polylysine backbone for charge variations, near-infrared fluorophores for bioimaging, and β-cyclodextrins for potential drug delivery. H-Dots show ideal systemic circulation and rapid distribution and excrete from normal tissue/organ via renal excretion after complete targeting to the tumor site without nonspecific uptake by the immune system.
肾清除两性离子纳米载体 (H-Dots) 由 ε-聚赖氨酸骨架组成,用于电荷变化,近红外荧光团用于生物成像,β-环糊精用于潜在的药物输送。H-Dots 在完全靶向肿瘤部位后,显示出理想的系统循环和快速分布,并通过肾脏排泄从正常组织/器官中快速排出,而不会被免疫系统非特异性摄取。
