摘要: Upconversion nanocrystals (UCNs) display near‐infrared (NIR)‐responsive photoluminescent properties for NIR imaging and drug delivery. The development of effective strategies for UCN integration with other complementary nanostructures for targeting and drug conjugation is highly desirable. This study reports on a core/shell‐based theranostic system designed by UCN integration with a folate (FA)‐conjugated dendrimer for tumor targeting and with photocaged doxorubicin as a cytotoxic agent. Two types of UCNs …
