Unraveling the interaction between doxorubicin and DNA origami nanostructures for customizable chemotherapeutic drug release
Doxorubicin (DOX) is a commonly employed drug in cancer chemotherapy, and its high DNA-binding affinity can be harnessed in preparing programmable DOX-loaded DNA nanostructures that can be further tailored for targeted delivery and therapeutics. Although DOX has been widely studied, the existing literature of promising DOX-loaded DNA nanocarriers remains limited and incoherent. A number of reports have over-looked the fundamentals of the DOX-DNA interaction, let alone the peculiarities arising from the complexity of the system as a whole. Here, based on an in-depth spectroscopic analysis, we characterize and optimize the DOX loading into different 2D and 3D scaffolded DNA origami nanostruct…
