Nucleic acid-functionalized metallic nanoparticles (N-MNPs) precisely integrate the advantageous characteristics of nucleic acids and metallic nanomaterials, offering various abilities such as resistance to enzymatic degradation, penetration of physiological barriers, controllable mobility, biomolecular recognition, programmable self-assembly, and dynamic structure-function transformation. These properties demonstrate significant potential in the field of biomedical diagnostics and therapeutics. In this review, we examine recent advancements in the construction and theranostic applications of N-MNPs. We briefly summarize the methodologies employed in the conjugation of nucleic acids with metallic nanoparticles and the formation of their superstructural assemblies. We highlight recent representative applications of N-MNPs in biomolecular diagnosis, imaging, and smart delivery of theranostic agents. We also discuss challenges currently faced in this field and provide an outlook on future development directions and application prospects.
