However, achieving programmable release of payloads with diverse molecular weights at distinct rates typically requires complex polymer designs that can compromise the accessibility and biocompatibility of the delivery system. We present a scalable method for producing injectable, micrometer-scale alginate hydrogel particles (microgels) with precisely tuned microstructures for multiplexed, programmable cargo release. Our approach integrates an established jetting technique with a simple postsynthesis ion-exchange process to fine-tune the cross-linked microstructure of alginate microgels. By varying cation type (Ca2+, Mg2+, Na+) and concentration, we systematically modulate the microgels' chemical and physical properties to control release rates of model compounds, including rhodamine B, methylene blue, and dextrans of various molecular weights. Additionally, a PEG-alginate composite microgel system is used to demonstrate the pre-programmed stepwise release of rhodamine B. These findings offer a straightforward strategy for postsynthetic manipulation of ionic microgels with controllable release performances, paving the way for advanced biomedical applications.","PeriodicalId":100230,"journal":{"name":"Chem & Bio Engineering","volume":"2 5","pages":"312-321"},"PeriodicalIF":0.0,"publicationDate":"2025-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12104843/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144164135","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

When dealing with bulk molecules, the acid sites located on the external surface often serve as the primary active sites, and thus, the distribution of Al sites significantly impacts the active acidity and catalytic performance. In this study, a precise modulation of Al distribution within MWW zeolites was investigated using commercially available N,N,N-trimethyl-1-adamantylammonium hydroxide (TMAdaOH) and cyclohexylamine as organic structure-directing agents (OSDAs). The effects of both OSDAs, along with the synthesis temperature, duration and Na+, on the formation of the MWW framework were systematically examined. Advanced solid-state NMR characterization addressed the correlation between Al and organic species. The presence of TMAdaOH showed significant influence on the distributions of cyclohexylamine and T2 Al sites as well as the benzene transport rate, resulting in MWW zeolites with enriched external surface accessible active acid sites. Owing to these properties, the MWW zeolites exhibited superior catalytic performance compared to conventional MCM-22 zeolites in the cracking of TiPB and alkylation of benzene with cyclohexene. This study highlights the successful synthesis of MWW zeolites using small amounts of low-toxicity OSDAs, offering a scalable and economical approach for the production of zeolites with enhanced catalytic properties for industrial applications.","PeriodicalId":100230,"journal":{"name":"Chem & Bio Engineering","volume":"2 6","pages":"358-369"},"PeriodicalIF":0.0,"publicationDate":"2025-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12207279/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144546763","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
