However, the sandwich-structured hydrogels still face the preparation problems of a layer-by-layer construction process and complicated operation method. In this paper, a one-step preparation of sandwich-structured hydrogels with adjustable inner layer thickness was realized, wherein the inner layer of the hydrogel was enriched by PEDOT:PSS, and the outer layer of the hydrogel was polymerized by acrylamide (AM) and zwitterionic monomer (SBMA). By adjusting the content of AM and SBMA, the enrichment of PEDOT:PSS could be affected, achieving the regulation of the inner layer thickness on conductivity. The introduction of glycerol (GL) into the outer layer of the sandwich-structured hydrogel imparted excellent environmental stability to the hydrogel. Therefore, a sandwich-structured hydrogel with high conductivity (511.29 ms/cm), significant deformability (1720%), and excellent environmental stability was obtained. The sandwich-structured hydrogel could not only be used as wearable sensors to detect human movement over a large temperature range of −20 to 60 °C but could also be woven into flexible fabric sensors for position sensing and Morse code transmission, showing promising applications in the field of multifunctional sensing.","PeriodicalId":33,"journal":{"name":"Chemistry of Materials","volume":"37 9","pages":"3063–3072 3063–3072"},"PeriodicalIF":7.2,"publicationDate":"2025-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143934227","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}

Thus, the construction of NO-releasing polymeric vehicles has garnered much attention. Despite the great effort made in the field, facilitating the internalization of polymer-based NO donors within cells remains a challenge. In this work, we reported a rational design of poly(trimethylenecarbonate) (PTMC)-based NO-releasing polymersomes equipped with cell-penetrating guanidine. The guanidine group conjugated with the polymersome significantly enhances the cellular uptake efficiency induced by the unique interactions between guanidine and the cancer cell surface. The in vitro studies demonstrated that light irradiation could trigger NO release from polymersomes, and the guanidine-functionalized polymersomes have superior cytotoxicity against cancer cells than unfunctionalized polymersomes. We expect that integrating cell-penetrating properties into NO-releasing polymersome systems provides a promising strategy for constructing advanced gas-releasing polymeric vehicles.","PeriodicalId":33,"journal":{"name":"Chemistry of Materials","volume":"37 9","pages":"3434–3442 3434–3442"},"PeriodicalIF":7.2,"publicationDate":"2025-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143934352","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}
