Characterized by the spectrin repeat (SR) domain, this superfamily features a unique bundle of three antiparallel α-helices. These SRs often appear as tandem repeats linked by short segments, serving as tension-bearing structural units that support the cytoskeleton and act as signaling hubs for numerous proteins. Although the cooperative force-dependent unfolding of tandem spectrin repeats is well-documented, the precise molecular mechanisms remain unclear. In this study, we used the paradigmatic tandem SR (SR3-SR4) of α-actinin as our model system. Our results reveal that cooperativity arises from the salt bridges on the linker between the two domains. Additionally, we found that the salt bridge mechanically stabilizes the two domains, extending the lifetime of SR3-SR4 by 10 to 100 times compared to individual domains. Our full-atom MD simulations show that the linker salt bridge is a major force-bearing point, and its disruption leads to the mechanical unfolding of the domains. Finally, combining AlphaFold structural prediction and single-molecule manipulation studies of other spectrin superfamily proteins, we demonstrate that linker salt bridge-mediated cooperativity and stabilization is a potentially conserved molecular mechanism governing the mechanical responses of SRs in spectrin superfamily proteins.</p>","PeriodicalId":93,"journal":{"name":"Nanoscale Horizons","volume":" ","pages":""},"PeriodicalIF":8.0,"publicationDate":"2025-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144256859","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Unlike conventional wearable devices, which rely on substrates, tattoo electrodes are directly formed or transferred onto the skin or internal organs, ensuring superior comfort, breathability, and long-term usability. This intimate interface minimizes motion-induced artifacts and enables reliable biosignal acquisition across diverse physiological and anatomical regions. However, the absence of a supporting substrate imposes unique challenges in fabrication and material design. The fabrication processes must be tailored to accommodate direct skin application, and the selection of functional materials is more constrained. Materials must not only be biocompatible and flexible but also capable of maintaining performance under the dynamic conditions of the human body. This review presents a comprehensive overview of tattoo electrode technology, beginning with fabrication strategies, including direct and indirect patterning methods. We then discuss a range of materials, such as metallic networks, carbon-based materials, polymers, and materials recently being studied.

However, salt ion accumulation and crystallization persist during long-term operation, which remains a key challenge. In this work, we report a hydrophilic-hydrophobic Janus nanofiber membrane evaporator, which is prepared <i>via</i> continuous microfluidic electrospinning. This method allows <i>in situ</i> chemical reaction of tannin (TA) and Fe³⁺ to be carried out in a \"Y\" chip during the spinning process, enabling rapid, facile, and flexible fabrication of the nanofiber membrane. TA is rich in hydroxyl groups, which endows the bottom layer with hydrophilicity and electronegativity, thereby enhancing the water transport and Donnan effect. Thus, a high evaporation rate of 1.73 kg m^-2 h^-1 in pure water is achieved. More importantly, long-term stability in seawater desalination is realized with an evaporation rate of 1.68 kg m^-2 h^-1, and there is no salt crystallization on the surface during continuous evaporation for 8 hours in 10 wt% NaCl solution. On the one hand, the bottom layer shows electronegativity, which is liable to immobilize cations Na⁺ and repel anions Cl^-, achieving the purpose of salt resistance. On the other hand, the Janus structure also favors the redissolution of concentrated salts into raw water, further avoiding salt accumulation.

Nonetheless, their inherent biomolecular limitations pose significant challenges, including cost and storage constraints. We propose an alternative conjugation for antibodies based on catalytic bimetallic nanoclusters and their integration in such simple colorimetric paper-based immunoassay. The nanoclusters are composed of gold and platinum and they are embedded in the structure of an anti-rabbit antibody, integrating in a single component the biorecognition and transduction elements required for biosensing. The detection is based on the catalytic properties of the NCs to oxidize an insoluble chromogenic substrate, generating a visible signal on the surface of the paper that can be further analysed for quantitative results. We demonstrate the detection of antibodies against the inflammation biomarker interleukin-6 with a limit of detection of 200 ng mL^-1. Experimental results reveal improvements in terms of stability compared to the natural enzyme horseradish peroxidase, retaining most of its activity after a storage equivalent to 6 months at 4 °C.
