Article Abstract
DNA, as a carrier of genetic information, has further been efficiently utilized as a foundational element in creating diverse nanostructures of different shapes and sizes through precise base pairing. With spatial addressability, structural programmability, and remarkable biocompatibility, self-assembled DNA-based nanostructures have been broadly applied in various biomedical research areas, such as bio-imaging, disease diagnosis, and drug delivery. Of particular note, immunotherapy, known for its outstanding therapeutic efficacy, has garnered much attention. In this review, we highlight the recent applications of DNA-based nanostructures (including DNA junction, DNA polyhedron, DNA origami, RCA-based DNA structure, DNA hydrogel, and spherical nucleic acid) in immunotherapy (based on the delivery of CpG adjuvant, tumor antigen, PD1 inhibitor, mRNA vaccine, virus antigen, or direct regulating immune cells). Furthermore, the challenges and future prospects of DNA-based nanostructures for in vivo immunotherapy are discussed.

DNA data storage is a promising alternative to conventional storage due to high density, low energy consumption, durability, and ease of replication. While information can be encoded into DNA via synthesis, high costs and the lack of rewriting capability limit its applications beyond archival storage. Emerging "hard drive" strategies seek to encode data onto universal DNA templates without de novo synthesis, using methods such as DNA nanostructures and base modifications.

Self-assembled DNA nanostructures have been popularly used to develop DNA-based electrochemical sensors by exploiting the nanoscale positioning capability of DNA origami. However, the impact of the electric field on the structural stability of the DNA origami framework and the activity of carried DNA probes remains to be explored. Herein, we employ DNA origami as structural frameworks for reversible DNA hybridization, and develop a single-molecule fluorescence imaging method to quantify electric field effects on DNA conformation and hybridization properties at the single-molecule level.

DNA exhibits remarkable versatility, which is attributed to its inherent molecular recognition capabilities, programmable sequences, and excellent biocompatibility. Among its various topological forms, branched DNA (bDNA), including Y-shaped DNA (Y-DNA), X-shaped DNA (X-DNA), etc., stands out as a fundamental building block for fabricating functional DNA-based materials and has demonstrated great promise across diverse applications in recent years.
