A self-assembled DNA nanostructure for targeted and pH-triggered drug delivery to combat doxorubicin resistance

We developed a novel self-assembled DNA nanostructure for anticancer drug delivery. The resulting nanostructure was able to specifically target cancer cells and release the loaded drug at pH 5.0. More importantly, the drug-loaded DNA nanostructure effectively circumvented doxorubicin resistance of human lung adenocarcinoma epithelial cancer cells.
