Abstract
Molecular strain can be introduced to influence the outcome of chemical reactions. Once a thermodynamic product is formed, however, reversing the course of a strain-promoted reaction is challenging. Here, a reversible, strain-promoted polymerization in cyclic DNA is reported. The use of nonhybridizing, single-stranded spacers as short as a single nucleotide in length can promote DNA cyclization. Molecular strain is generated by duplexing the spacers, leading to ring opening and subsequent polymerization. Then, removal of the strain-generating duplexers triggers depolymerization and cyclic dimer recovery via enthalpy-driven cyclization and entropy-mediated ring contraction. This reversibility is retained even when a protein is conjugated to the DNA strands, and the architecture of the protein assemblies can be modulated between bivalent and polyvalent states. This work underscores the utility of using DNA not only as a programmable ligand for assembly but also as a route to access restorable bonds, thus providing a molecular basis for DNA-based materials with shape-memory, self-healing, and stimuli-responsive properties.

Abstract
In recent years, DNA has emerged as a fascinating building material to engineer hydrogel due to its excellent programmability, which has gained considerable attention in biomedical applications. Understanding the structure-property relationship and underlying molecular determinants of DNA hydrogel is essential to precisely tailor its macroscopic properties at molecular level. In this review, the rational design principles of DNA molecular networks based on molecular dynamics of polymers on the temporal scale, which can be engineered via the backbone rigidity and crosslinking kinetics, are highlighted. By elucidating the underlying molecular mechanisms and theories, it is aimed to provide a comprehensive overview of how the tunable DNA backbone rigidity and the crosslinking kinetics lead to desirable macroscopic properties of DNA hydrogels, including mechanical properties, diffusive permeability, swelling behaviors, and dynamic features. Furthermore, it is also discussed how the tunable macroscopic properties make DNA hydrogels promising candidates for biomedical applications, such as cell culture, tissue engineering, bio-sensing, and drug delivery.

Abstract
A novel kinetically interlocking multiple-units (KIMU) supramolecular polymerization system with DNA double crossover backbone is designed. The rigidity of DX endows the polymer with high molecular weight and stability. The observed concentration of the formed polymers is insensitive and stable under ultralow monomer concentration owing to the KIMU interactions, in which multiple noncovalent interactions are connected by the phosphodiester bonds. Furthermore, a pH-responsive DNA supramolecular hydrogel is constructed by introducing a half i-motif domain into the DNA monomer. The rigidity of DNA polymer endows the hydrogel with high mechanical strength and low gelation concentration. This study enriches the KIMU strategy and offers a simple but effective way to fabricate long and stable supramolecular polymers by balancing the reversibility and stability. It also shows great potentials to construct next generation of smart materials, such as DNA nanostructures, DNA motors, and DNA hydrogels.

Abstract
The designability, functionalization, and diverse secondary structures of DNA enable the construction of DNA motors with stimuli-responsiveness. Therefore, it has been widely used to fabricate functional systems or generate mechanical power under external stimuli, such as pH, light, heat, electrical, and chemical molecular signals. Furthermore, the DNA motor has also been demonstrated to promote the applications of smart devices and materials, particularly in controllable drug delivery and reversible molecular switching. In this review, we have summarized and discussed recent progress of the construction and applications of DNA motor-based functional systems, such as responsive nanodevices, modified surfaces, and hydrogels.

Abstract
Herein, we report a novel strategy to enhance the antisense activity and the pharmacokinetics of therapeutic oligonucleotides. Through the DNA hybridization chain reaction, DNA hairpins modified with poly(ethylene glycol) (PEG) form a bottlebrush architecture consisting of a double-stranded DNA backbone, PEG side chains, and antisense overhangs. The assembled structure exhibits high PEG density on the surface, which suppresses unwanted interactions between the DNA and proteins (e.g., enzymatic degradation) while allowing the antisense overhangs to hybridize with the mRNA target and thereby deplete target protein expression. We show that these PEGylated bottlebrushes targeting oncogenic KRAS can achieve much higher antisense efficacy compared with unassembled hairpins with or without PEGylation and can inhibit the proliferation of lung cancer cells bearing the G12C mutant KRAS gene. Meanwhile, these structures exhibit elevated blood retention times in vivo due to the biological stealth properties of PEG and the high molecular weight of the overall assembly. Collectively, this self-assembly approach bears the characteristics of a simple, safe, yet highly translatable strategy to improve the biopharmaceutical properties of therapeutic oligonucleotides.
