Here, we propose an edge-oriented modification strategy by precisely confining ultrafine Co3O4 nanoclusters on the edges of ReS2 via interfacial Re–O–Co chemical bridging (Co3O4@ReS2). Unlike conventional surface modifications, this chemical bonding confinement enables selective edge growth, enhancing charge transfer and optimizing the electronic structure. Theoretical and experimental analyses reveal that the interfacial oxygen atoms act as active sites for the hydrogen evolution reaction (HER), facilitating H* adsorption via continuous gap states, while the spin-state transition of Co3+ from low-spin to intermediate/high-spin improves oxygen intermediate adsorption, boosting the oxygen evolution reaction (OER) and oxygen reduction reaction (ORR). As a result, Co3O4@ReS2 exhibits outstanding trifunctional electrocatalytic performance, achieving low overpotentials of 76 mV for the HER and 260 mV for the OER at 10 mA cm–2, along with an ORR onset potential of 0.88 V. This study establishes an edge-site engineering approach for TMDC-based electrocatalysts, offering a promising pathway for enhancing energy conversion efficiency.","PeriodicalId":21,"journal":{"name":"ACS Nano","volume":"81 1","pages":""},"PeriodicalIF":17.1,"publicationDate":"2025-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143885293","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While there has been significant progress in achieving precise control over the morphology of self-assembled structures, combining different molecules within assemblies enables the design of materials with increased complexity, sophisticated structures, and a broad spectrum of functionalities. Here, the development of 1D and 2D peptide–protein coassembled systems based on the design of amphiphilic peptides and engineered proteins is described. The peptide was optimized to form stable self-assembled fibers by evaluating, computationally and experimentally, the assembling tendencies and the supramolecular features of peptides with different lengths and negative charges. A superhelical repeat protein was engineered by fusing one or two amphiphilic peptides into one or both termini. This modification drove the coassembly between the self-assembled fibers and the protein with one or two peptides, resulting in 1D or 2D coassembled systems. The protein films and the 2D coassembled system exhibited high ionic conductivity for a biomolecular system, attributed to their high content of charged residues, positioning these materials as promising candidates for developing bioelectronic devices. Thus, this work provides a versatile framework for developing coassembled materials with tunable dimensionality by using biocompatible building blocks without any additional chemical moieties, highlighting the potential for their use in biocompatible electronics.","PeriodicalId":21,"journal":{"name":"ACS Nano","volume":"63 1","pages":""},"PeriodicalIF":17.1,"publicationDate":"2025-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143872559","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the full potential of the diverse compositions and functionalities of BHJs has yet to be explored for neuromodulation due to their unsatisfactory interfaces with soft biotissues, which hinder signal transduction, tissue adhesion, and biocompatibility. Here, we address these challenges by introducing an interfacial layer composed of conductive and porous metal–organic frameworks (MOFs). The MOFs layer enhances charge injection capacity at the interface by >400 times and ensures tight and biocompatible junction between BHJs and biological materials. These improvements enable efficient electrical-to-ionic signal transduction for various BHJs, supporting reliable nongenetic modulation of cultured mouse hippocampal neurons under deep-red and near-infrared light. Moreover, flexible devices made from MOFs-modified BHJs allow for the in vivo stimulation of rat sciatic nerves at an ultralow light intensity threshold (0.01 mW mm–2), 700 times lower than that required for unmodified devices. This interfacial engineering with porous MOFs can expand the material toolbox of BHJs-based photocapacitors and unlock more functionalities for neuromodulation and prosthetic biointerfaces.","PeriodicalId":21,"journal":{"name":"ACS Nano","volume":"38 1","pages":""},"PeriodicalIF":17.1,"publicationDate":"2025-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143875961","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The standard treatment, oral benznidazole, effectively targets the parasitic burden but does not address the chronic inflammation nor prevent the progression of severe cardiomyopathies. This presents an inherent immunotherapeutic challenge, as implementing an anti-inflammatory approach can have the unwanted effect of inhibiting beneficial parasite-specific immunity. Here, we investigated a combination therapy approach using benznidazole and immunomodulatory rapamycin-loaded poly(ethylene glycol)-b-poly(propylene sulfide) polymersome nanocarriers in a chronic Chagas disease murine model with cardiac abnormalities. The combined treatment demonstrated effective management of both inflammation and parasitic burden at systemic and local levels. No systemic reactivation of T. cruzi infection was observed, along with cardioprotective immunomodulatory effects through the modulation of cytokines, management of parasitic burden, and improved cardiac function based on electrocardiography assessment. The combination treatment enhanced a protective cytokine response in the heart, characterized by increased anti-inflammatory IL-10 levels, achieving greater effects than standard benznidazole treatment, and normalized TNF-α levels. Localized immunomodulatory effects, along with parasitic burden control, extended to other solid tissues relevant to parasite pathology and reservoirs. These findings highlight the therapeutic potential of modulating the immune response in chronic Chagas disease with rapamycin polymersomes and emphasize the importance of precise treatment timing in the strategy’s efficacy.","PeriodicalId":21,"journal":{"name":"ACS Nano","volume":"8 1","pages":""},"PeriodicalIF":17.1,"publicationDate":"2025-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143875960","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
