We use a strong-segregation approach to compute the free energy of double network morphologies as a function of two structural parameters that convert between two limiting cubic cases: a tetragonal stretch of the unit cell in combination with fusion of pairs of trihedal gyroid nodes into tetrahedral diamond nodes. For the simplest case of conformationally symmetric diblock melts, we find that cubic double-diamond sits at an unstable saddle point that is continuously deformable into the lower free energy gyroid, as well as a second metastable, tetragonal network composed of trihedral nodes. We confirm the broad instability of double-diamond at finite segregation using self-consistent field studies and further show that it derives directly from the entropic free energy cost of chain packing in the tubular domains of tetrahedral nodes. Correspondingly, we demonstrate two factors that quench the entropic cost of packing in the tubular domain─homopolymer blending and elastic asymmetry between the blocks─and promote double-diamond to a metastable state by way of a free energy barrier that separates it from double-gyroid.","PeriodicalId":18,"journal":{"name":"ACS Macro Letters","volume":"14 9","pages":"1291–1298"},"PeriodicalIF":5.2,"publicationDate":"2025-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144935802","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}

However, shape-switching particles sensitive to light are rarely reported. Herein, a robust and facile strategy for the production of photoresponsive block copolymer (BCP) assemblies is developed via three-dimensional restricted coassembly of polystyrene-b-poly(4-vinylpyridine) (PS-b-P4VP) and azobenzene (Azo)-based photoactive additives under emulsion droplets. Upon alternating exposure to ultraviolet and visible light, trans–cis isomerization of the Azo group causes the hydrophobic–hydrophilic transition of Azo within the P4VP phases. Therefore, the particle shape and internal nanostructure could be reversely modulated between an onion shape with a PS outer layer and an inverted onion with P4VP at the interface. Notably, the light-driven morphological behavior of BCP assemblies exhibits promising potential in controlled drug release, which positions them as compelling candidates for advanced biomedical and clinical systems.","PeriodicalId":18,"journal":{"name":"ACS Macro Letters","volume":"14 9","pages":"1284–1290"},"PeriodicalIF":5.2,"publicationDate":"2025-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144935813","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}

Though so far primarily focused on the assembly of coacervate nanostructures, we leverage polymerization-induced electrostatic self-assembly (PIESA) to achieve control over the composition and sequence of neutral-ionic copolymers and create complex chain topologies from equimolar mixtures of neutral and ionic monomers in a direct, one-pot process in aqueous solution. We are making use of the selective recruitment of charged over neutral monomers on an oppositely charged template to modulate monomer reactivities in situ during a controlled radical polymerization by creating segregated reaction environments. Varying the charge density of the template simply through cycling between acidic and alkaline pH drives the preferential incorporation of ionic over charge-neutral monomers by switching the template ON and OFF. Fine-tuning the length and order of the switching cycles enables the on-demand programming of specific block sequences and compositions, and even unique, alternating multiblock-like structures become accessible in a straightforward, one-pot process. Our results demonstrate a novel concept in taking advantage of the selectivity and reversibility of supramolecular compartmentalization of (charged) macromolecular building blocks to control and modulate monomer reactivities and chain topologies.","PeriodicalId":18,"journal":{"name":"ACS Macro Letters","volume":"14 9","pages":"1277–1283"},"PeriodicalIF":5.2,"publicationDate":"2025-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12444980/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144935848","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}

The polymerization kinetics revealed that the polymerizations were well-controlled with living characteristics, resulting in diblock copolymers PHcy-b-PBLG with narrow molecular weight distributions. The resulting functional-hydrophobic diblock copolymers were further converted to a variety of pendant chains via thiol–disulfide exchange reactions, yielding amphiphilic polymers with tunable surface charges. These disulfide-linked materials readily self-assembled into nanoparticles in aqueous environments with hydrophobic PBLG forming the core and redox-sensitive PHcy forming the shell. The redox-responsive nanoparticles displayed a narrow size distribution, excellent colloidal stability, and excellent biocompatibility. The disulfide bonds within the polymer backbone confer redox sensitivity, allowing potential cleavage in reducing environments. Owing to their tunable surface functionality, redox-responsiveness, and biocompatibility, this platform provides a versatile route to engineer responsive nanostructures for biomedical applications, for example, positively charged nanoparticles toward nucleic acid delivery.","PeriodicalId":18,"journal":{"name":"ACS Macro Letters","volume":"14 9","pages":"1263–1268"},"PeriodicalIF":5.2,"publicationDate":"2025-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144870159","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}

In both systems, the total PS domain size is constrained by a “neutral” nonperturbing silica substrate. Remarkably, for this constrained PnBMA/PS bilayer system, we find the perturbing influence of the 6–7 nm PnBMA/PS interface to be essentially equivalent to that imposed by the free surface, in stark contrast to the previously reported long-range Tg(z) perturbations of up to ≈250 nm for unconstrained glassy–rubbery interfaces between semi-infinite domains. For the 75 nm PS domains, both the PnBMA interface and free surface impart a local Tg(z) reduction of ≈30 K, spanning ≈30 nm before bulk Tg is recovered, demonstrating that the total domain size strongly alters both the magnitude and extent of the dynamical gradient even when bounded by a nonperturbing interface.","PeriodicalId":18,"journal":{"name":"ACS Macro Letters","volume":"14 9","pages":"1256–1262"},"PeriodicalIF":5.2,"publicationDate":"2025-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12444983/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144870160","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}

Free-radical copolymerization of this cross-linker with n-hexyl methacrylate yielded robust CANs with full property recovery upon reprocessing by compression molding at 120 °C. The associative azine dynamic chemistry resulted in constant cross-link density across the rubbery plateau, extraordinary creep suppression at temperatures of 190–210 °C, and severely limited stress relaxation at temperatures as high as 200–210 °C; nevertheless, this did not hinder the CAN’s reprocessability by compression molding at 120 °C and 8 MPa pressure.

Synthetic hydrogels are widely used for this purpose, but while they offer advantages such as tunability and mechanical stability, they lack the range of biochemical signals present in the native microenvironment. On the other hand, decellularized extracellular matrices (dECMs) retain native biochemical signals but their adoption as stable in vitro culture platforms is limited due to batch variability, poor mechanical stability, and limited tunability. Here we report the development of hybrid hydrogels comprising dECM and a photocurable norbornene-modified hyaluronic acid (NorHA) polymer. To overcome structural heterogeneity of dECM that inhibits its solubility, uniform gelation, and spatial uniformity during cell culture, we physically process dECM by grinding, shearing, or both, prior to incorporation within NorHA. Both processing methods reduce microscale dECM aggregation and improve physical gelation at 37 °C. The addition of dECM up to 10 mg/mL within NorHA hydrogels neither affects rapid UV cross-linking nor compromises mechanical properties, as evaluated using oscillatory shear rheology and uniaxial compression testing. Both processes significantly improve the uniform distribution of dECM within 3D hybrid hydrogels, as evaluated by staining hydrogel cryosections. Fibroblasts show significantly higher spreading area and proliferation on hybrid hydrogels compared with control NorHA hydrogels. Taken together, photocurable hybrid hydrogels having uniformly distributed dECM combine the biochemical complexity of native dECM with the tunability of a synthetic polymer and represent an advance in the engineering of biomimetic platforms to investigate cell–matrix interactions.","PeriodicalId":18,"journal":{"name":"ACS Macro Letters","volume":"14 9","pages":"1241–1247"},"PeriodicalIF":5.2,"publicationDate":"2025-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144843774","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}
