Cancer chemotherapy has been limited by its side effects and multidrug resistance (MDR), the latter of which is partially caused by drug efflux from cancer cells. Thus, targeted drug delivery systems that can circumvent MDR are needed. Here, we report multifunctional DNA nanoflowers (NFs) for targeted drug delivery to both chemosensitive and MDR cancer cells that circumvented MDR in both leukemia...
Chlorin e6-pHLIPss-AuNRs, a gold nanorod-photosensitizer conjugate containing a pH (low) insertion peptide (pHLIP) with a disulfide bond which imparts extracellular pH (pHe)-driven tumor targeting ability, has been successfully developed for bimodal photodynamic and photothermal therapy. In this bimodal therapy, chlorin e6 (Ce6), a second-generation photosensitizer (PS), is used for photodynamic therapy...
