However, concerns regarding their sustainability have arisen due to the uneven global distribution of Li resources and Li's relatively low abundance in the Earth's crust. Consequently, significant interest has shifted toward developing alternative SSBs, such as sodium (Na), magnesium (Mg) and Aluminum (Al)-ion batteries. A key challenge in this pursuit is efficiently identifying viable solid-state electrolytes (SEs) from the vast chemical space, particularly for Na and Mg ions. This study introduces a generalized framework based on machine learning for effectively screening high-performance garnet-type SEs. Utilizing specifically designed chemical descriptors, ML models predict the thermal stability and electrical conductivity of garnet-type SEs, achieving predictive accuracies of 94% and 89%, respectively. The chemical factors influencing stability and conductivity are identified and validated through interpretability analysis. Leveraging these models, 1764 garnet-type SEs exhibiting high thermal stability and wide band gaps were screened from a database of 43,732 compounds. Furthermore, 44 garnet-type SEs with favorable environmental and economic advantages were selected, and verified through first-principles calculations using density functional theory. Given their cost-effectiveness and high performance, these SEs hold great potential for application in Na, Mg, and Al ion SSBs.

However, it faces substantial challenges due to on-target off-tumor effects arising from nonspecific expression of target proteins. To address this issue efficiently, we report here a pH-responsive allosteric DNA nanorobot (named A/I) that enhances the precision of aptamer-mediated target protein degradation through tumor microenvironment-specific activation. The allosteric nanorobot is comprised of two modules: the recognition module (A-strand) and the response module (I-strand). To be specific, the A-strand integrates both target recognition and degradation-inducing capabilities, while the I-strand blocks the recognition sites of the A-strand through complementary base pairing and confers pH sensitivity. Under physiological pH conditions, the A/I nanorobot exists stably in the form of a double-stranded structure. When the acidic tumor microenvironment is encountered, the pH-triggered conformational change of the I-strand induces the duplex disassembly, releasing the A-strand, which can specifically bind to the target protein and subsequently induce its degradation. Our findings demonstrate that the activatable allosteric nanorobot achieves targeted protein degradation, significantly inhibiting the proliferative and migratory abilities of tumor cells. In general, the activatable allosteric nanorobot has innovatively overcome the bottleneck of insufficient selectivity in traditional aptamer-based protein degradation strategies, providing a molecular tool for precision tumor therapy technologies. In addition, the allosteric nanorobot features a simple design and enables specific degradation of diverse target proteins by flexible replacement of the recognition module, demonstrating significant potential for constructing a universal protein precise degradation platform.</p>","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":" ","pages":"41781-41791"},"PeriodicalIF":8.3,"publicationDate":"2025-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144598872","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
