Herein, we engineered a multifunctional ultra-porous Alg/MMT sponge derived from alginate and enriched with montmorillonite (MMT) nanosheets serving as bioactive agents, utilizing gas-foaming, ionic crosslinking, and lyophilization processes. The sponge exhibited antibacterial effectiveness targeting <em>S. aureus</em> and <em>E. coli</em>, as evidenced by inhibition zone, minimum inhibitory concentration (MIC), and minimum bactericidal concentration (MBC) assays. The fabricated Alg/MMT sponge demonstrated biocompatibility by maintaining high cell viability and promoting cell proliferation, as confirmed by MTT and DAPI assays. <em>In-vitro</em> evaluations revealed enhanced efficacy over EquiSpon® in blood clotting (9.15%), adherence of erythrocytes (94.50%) and platelets (87.30%), as well as clotting time of 19 s (P-value < 0.001). Through a femoral artery trauma model in rats, the Alg/MMT sponge delivered a hemostatic effect, reducing blood loss to 0.75 g and achieving hemostasis in 32.66 s—representing a 7.5-fold improvement compared to EquiSpon® (P-value < 0.001). Together, these characteristics highlight the Alg/MMT sponge as a reliable hemostatic agent for clinical environments.</div></div>","PeriodicalId":100213,"journal":{"name":"Carbohydrate Polymer Technologies and Applications","volume":"13 ","pages":"Article 101068"},"PeriodicalIF":6.5,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145926149","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
