DNA hydrogels possess numerous unique and attractive features, including excellent biocompatibility and biodegradability, as well as inherent programmability, catalytic functionality, therapeutic potential, and precise molecular recognition and bonding capabilities. Furthermore, intelligent DNA hydrogels exhibit stimuli-responsive behaviors, transitioning between gel and sol states in response to various stimuli, including pH, temperature, enzymes, and others. Through intelligent, rational design and controlled preparation of DNA nanostructures, a broad spectrum of advanced applications has been realized. In this minireview, we focus on recent developments in the construction strategies, molecular structures, and functional mechanisms of DNA hydrogels. Additionally, representative applications of stimuli-responsive DNA hydrogels are discussed. Finally, challenges and the future outlook of DNA hydrogels are proposed.

Compared to sun-exposed melanomas, acral melanomas are genetically diverse and occur in areas with low sun exposure and high mechanical loads. During metastatic growth, melanomas invade from the epidermis to the dermis layers through dense tumor stroma and are exposed to fibrillar collagen architectures and mechanical stresses. However, the role of these signals during acral melanoma pathogenesis is not well understood.

Radiotherapy (RT) is a key component of comprehensive cancer treatment regimens; nevertheless, its concomitant immunosuppression may diminish therapeutic efficacy. In this study, we developed an injectable hydrogel system for the local delivery of PROteolysis TArgeting Chimeras (PROTACs), achieved by loading tumor cell membrane-fused liposome nanoparticles to enhance the anti-tumor effect. The system targeted Bromodomain-containing protein 4 (BRD4), and combined treatment with RT promoted DNA damage, reduced DNA repair and decreased tumor cell proliferation and survival.

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.

Enzymatic deoxyribonucleic acid (DNA) synthesis (EDS) is an environmentally friendly approach capable of generating longer and more complex sequences than chemical synthesis, making it a promising next-generation technology for high-throughput single-stranded DNA production. However, precise sequence control at high throughput remains a key challenge. Here, we present a novel electronically controlled deprotection chemistry (ECDC) integrated with a hydrogel-primer modification system on-chip for efficient multiplexed EDS.
