DNA has been demonstrated to be a versatile material for construction at the nanoscale. DNA nanodevices are highly programmable and allow functionalization with multiple entities such as imaging modalities (fluorophores), targeting entities (aptamers), drug conjugation (chemical linkers), and triggered release (photoresponsive molecules). These features enhance the use of DNA nanodevices in biological applications, catalyzing the rapid growth of this domain of research. In this review, we focus on recent progress in the development and use of aptamer-functionalized DNA nanodevices as theranostic agents, their characterization, applications as delivery platforms, and advantages. We provide a brief background on the development of aptamers and DNA nanodevices in biomedical applications, and we present specific applications of these entities in cancer diagnosis and therapeutics. We conclude with a perspective on the challenges and possible solutions for the clinical translation of aptamer-functionalized DNA nanodevices in the domain of cancer therapeutics.
