However, their direct use as small-molecule agents is often challenging due to rapid systemic clearance, unfavorable biodistribution, and loss of catalytic efficacy under the diluted conditions of a biological milieu. Incorporating the metal complexes into a polymer addresses these issues, providing three key advantages. First, it significantly improves pharmacokinetics by leveraging the size, which leads to a prolonged circulation and an enhanced therapeutic index for systemically administered medicines. Second, the polymer matrix creates a locally concentrated environment for the metal complexes. Neighboring metal complexes allow for efficient reactions, such as the generation of reactive oxygen species, even under biologically dilute conditions. Third, the multivalent effect of multiple binding sites on the polymer chain dramatically increases molecular recognition and binding affinity. This can be the driving force for supramolecular formation, including nanoparticles and hydrogels. Combining these merits could advance a new generation of biomaterials, enabling various types of theranostics. The polymer matrix also promotes catalytic reactions of metal complexes that cannot feasibly proceed in an ordinary aqueous solution state, mirroring a biological system. Thus, we believe that polymer-metal complexes will further promote biomaterial development, including in medicines and artificial tissues.","PeriodicalId":18151,"journal":{"name":"Macromolecular Materials and Engineering","volume":"311 1","pages":""},"PeriodicalIF":4.6,"publicationDate":"2025-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/mame.202500319","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145986998","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}

The low bioavailability of antiepileptic drugs (AEDs) used for treatment and the inability to administer drugs orally during seizures highlight the need for new drug delivery systems. In the present study, the effect of ethosuximide (ETX) supplementation to polylactic acid (PLA)/bismuth ferrite (BFO, BiFeO3) mixture on epileptic seizures was investigated in detail. ETX-loaded fibers were created by adding ETX in different ratios (10, 15, and 20 mg) through the same procedures. The morphological analysis showed that the minimum diameter belonged to the 10% PLA fibers. According to the tensile testing results, the 10% PLA + 5 mg BFO fiber had the highest tensile strength value (2.49 ± 1.01 MPa). The biocompatibility results, performed with the human neuroblastoma cell line (SH-SY5Y), demonstrated that all fibers had no cytotoxic effect. The ETX release was performed both under and without an electric field in vitro conditions. The results demonstrated that the ETX released faster from fibers under an electric field.","PeriodicalId":18151,"journal":{"name":"Macromolecular Materials and Engineering","volume":"310 11","pages":""},"PeriodicalIF":4.6,"publicationDate":"2025-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/mame.202500312","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145522093","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}

Zinc oxide (ZnO) is promising due to its non-centrosymmetric structure, high piezoelectric coefficient, and versatile nanostructure synthesis. This review covers recent trends in fabricating and optimizing piezoelectric polymer nanocomposites based on fluoropolymers and ZnO, including synthesis principles and advanced methods.

It investigates the effect of core/shell ratio of the filament, and raster orientation via printing, to control the mechanical anisotropy of 3D-printed structures. Load frame experiments demonstrate control over a wide range of tensile modulus (50–2200 MPa) and flexural modulus (50–2600 MPa), by varying the number and sequence of 0°, ±45°, and 90° raster orientations (plies) within 16-layer test coupons. Asymmetric (with respect to the sample mid-plane) ply stacks are shown to exhibit a bending response that is sensitive to bending direction. Segmented designs, in which print orientation is varied along the length of a test coupon, are fabricated and exhibit localized bending. Analytical composite laminate theory and finite element simulations are shown to capture the broad trends in mechanical response for these 3D printed soft composites, although these models overpredict structural stiffness as ABS volume fraction increases due to strain localization and softening in the TPE phase.","PeriodicalId":18151,"journal":{"name":"Macromolecular Materials and Engineering","volume":"311 1","pages":""},"PeriodicalIF":4.6,"publicationDate":"2025-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/mame.202500285","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146096522","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}
