There is an urgent need for versatile carriers capable of multi-functional targeting without compromising functionality. Here, we report a dual surface modification strategy to enhance the therapeutic efficacy of microrobotic platforms, through controlled, site-specific drug release. This dual functionalization integrates two distinct pH-sensitive polymeric nanoreservoirs with different membrane permeability. One nanoreservoir is engineered to release an antitumor agent -curcumin- in response to the acidic tumor microenvironment, while the second is designed to degrade the tumor extracellular matrix via enzymatic activity, facilitating enhanced diffussion of the therapeutic agent. This dual surface modification approach represents a significant advancement in the customizable integration of multifunctional nanoreservoirs. By leveraging dual compartmentalization, it prevents deactivation and cross-process interference, enabling precise nanoscale combination therapies for microrobotic cancer treatment. These surface-engineered microrobots hold promise for overcoming physiological barriers, ensuring stable cargo transport, and broadening the applicability of microrobotic platforms across diverse cancer types.","PeriodicalId":18151,"journal":{"name":"Macromolecular Materials and Engineering","volume":"310 9","pages":""},"PeriodicalIF":4.6,"publicationDate":"2025-05-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/mame.202500058","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145062823","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to develop a printable and bioactive hydrogel scaffold suitable for bone tissue engineering by incorporating methylcellulose (MC) and hydroxyapatite (HA) into an alginate/gelatin (AlGel) hydrogel ink. The rheological studies are carried out for these hydrogels. Following this, degradation studies, morphological analysis are conducted for the 3D printed scaffolds. Mechanical properties, wettability, and bioactivity are analyzed following with cell culture and biomineralization studies. Rheological studies also demonstrated that enhanced printability is related to the higher viscosity of the hydrogels after MC incorporation. Notably, printability increased from 0.59 to 0.96 by the addition of 3 wt/v% MC. MC also highly improved the ductility of the scaffolds. HA enhanced both the bioactivity and mechanical strength. The compressive strength and % strain of the AlGelMC3HA1 scaffolds are 0.78 MPa and 100%, respectively. All samples degraded within 9 days. All samples has relatively high % viability of MC3T3 pre-osteoblast cells on day 3 which indicated cytocompatibility of the scaffolds. The calcium deposition is confirmed via Alizarin Red S staining for all study groups on day 14. Overall, the scaffolds show high potential for bone tissue engineering applications.","PeriodicalId":18151,"journal":{"name":"Macromolecular Materials and Engineering","volume":"310 9","pages":""},"PeriodicalIF":4.6,"publicationDate":"2025-05-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/mame.202500154","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145062822","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study investigates the influence of hard segment content on the low strain rate compression and high strain rate impact properties of waterborne polyurethane (WPU) by modulating the NCO/OH ratio. Mechanical responses are characterized using a universal testing machine and a split Hopkinson pressure bar (SHPB) system. Additionally, the hydrogen bonding and microphase separation structure are analyzed using FTIR, DSC, DMA, and SAXS. These findings reveal that the glass transition temperatures (TgDSC and TgDMA) shift toward higher temperatures with increasing hard segment content, which is attributed to the intensified hydrogen bonding cross-linked network, as corroborated by FTIR and SAXS analyses. The WPU demonstrates a pronounced strain rate sensitivity across a broad range of strain rates (10−4–104 s−1). Notably, the 45 wt.% hard segment WPU523 sample shows heightened sensitivity, attributed to complex hydrogen bonding heterogeneity and a higher Herman's orientation factor during loading, the key to WPU's dynamic mechanical response.","PeriodicalId":18151,"journal":{"name":"Macromolecular Materials and Engineering","volume":"310 9","pages":""},"PeriodicalIF":4.6,"publicationDate":"2025-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/mame.202500100","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145062627","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study shows that alginate and native casein micelles can be processed into stable composite fibers by extrusion in a calcium-rich coagulation bath. The influence of micellar casein content on the swelling of fibers in decalcifying media is analyzed and the effects of the treatment on the mechanical properties are investigated. Pure alginate fibers swell strongly in trisodium citrate solutions due to calcium removal, whereas alginate-casein interactions in composite fibers significantly reduce this strong swelling. In acidic solutions such as citric acid and glucono-δ-lactone, pure alginate fibers become softer and lose strength. If the amount of micellar casein in the fiber is increased, it can be observed that the swelling capacity decreases during the acid treatment, but the extensibility increases significantly in mechanical tests after the treatment. However, citric acid also stabilizes the fiber structure through hydrogen bonding and makes the fibers more flexible, which leads to a greater reduction in swelling and allows for higher breaking strains, compared to glucono-δ-lactone.","PeriodicalId":18151,"journal":{"name":"Macromolecular Materials and Engineering","volume":"310 9","pages":""},"PeriodicalIF":4.6,"publicationDate":"2025-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/mame.202500118","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145062626","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This review explores recent trends in the use of melt-processed CA materials for encapsulating and controlling the release of active compounds. It highlights the advancements made over the past decade in processing CA-based materials using thermoplastic techniques. Additionally, the review discusses the properties of these materials, including biodegradation, photodegradation, and solubility, which are important for delivering active agents.

The findings demonstrate a significant improvement in tensile strength and modulus, increasing from 5.38 ± 1.41 to 40.48 ± 4.74 MPa and from 27 ± 6.11 to 297.15 ± 68.29 MPa, respectively. This represents a 659% improvement in tensile strength and a nearly 1000% increase in modulus, highlighting the efficacy of the method. Compared to previous studies, this work introduces a low-temperature, scalable, and energy-efficient process that significantly enhances the mechanical properties, positioning it as an ideal candidate for applications in wearable electronics, energy storage, and advanced composite materials.
