摘要
Herein,we report a geometrically well-defined prism assembled by two floxuridine(F)integrated RNA strands as a precise nanomedicine for chemodrug delivery.Owing to the similarity between chemotherapeutic F and uridine(U),all uridines in the component RNA strands are replaced by F during their in vitro transcription syntheses.By specifically designing their sequences,F-containing S-shape tiles with the single-stranded loops are constructed and then further assemble into the RNA prism through T-junction interactions and sticky-end cohesions.The present study demonstrates that the F-integrated RNA prism can serve as an efficient platform for chemodrug delivery and anticancer treatment.We believe that the study would help the future development of RNA-based nanomedicine in various applications.
