In particular, bone metastasis stands as one of the leading causes of death among breast cancer patients. In recent years, therapies that reprogram the tumor's immunosuppressive microenvironment have emerged as promising antimetastatic strategies. In this study, we developed a sonodynamic nanoplatform that simultaneously eradicates primary breast tumors via ferroptosis and apoptosis and blocks their spread to bone tissues. Ferrocene-grafted nanoconfined covalent organic frameworks (mCOFs) were synthesized by condensing aminoferrocene with micrometer-sized COFs, yielding a multifunctional agent capable of amplifying reactive oxygen species (ROS) production. Following ultrasound treatment, the mCOFs generated abundant ROS, while the ferrocene moieties catalyzed the Fenton-like conversion of endogenous H2O2 into cytotoxic •OH radicals. In vitro, ultrasound-activated mCOFs concurrently induced apoptosis and ferroptosis in breast cancer cells and triggered the robust release of immunogenic factors. In orthotopic mouse models, intravenously administered mCOFs preferentially accumulated in tumors; upon ultrasound exposure, these mCOFs markedly inhibited the growth of primary tumors, reprogrammed the immunosuppressive tumor microenvironment, and effectively reduced bone metastasis. This study proposes a versatile nanomedicine-based strategy that integrates sonodynamic therapy with immunomodulation to control breast cancer progression and bone metastasis, offering a broad approach for reducing metastatic disease.","PeriodicalId":72764,"journal":{"name":"Cyborg and bionic systems (Washington, D.C.)","volume":"7 ","pages":"0490"},"PeriodicalIF":18.1,"publicationDate":"2026-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13006732/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147517108","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}

These biohybrid systems utilize living insects as mobile platforms while controlling their locomotion via electrical stimulation of sensory organs. Despite remarkable advancement in locomotion control, the deployment of these cyborgs is hindered by their deterioration in locomotory responses to electrical stimulation, which typically involves prolonged, continuous stimuli. This study proposes burst stimulation as an alternative to the conventional stimulation protocol to achieve more sustained responses of cyborg insects from darkling beetles (Zophobas morio). Implementing burst stimulation enhances the sustainability of beetle's responses, with the deterioration rate of the turning response to antenna stimulation reduced by 30%. The induced turning angle is 52% greater under burst stimulation, further advancing locomotion control. The graded response in turning is conserved when tuning the stimulation frequency from 10 to 40 Hz, promoting the integration of burst stimulation into feedback control systems for autonomous navigation of the cyborg beetle. The cyborg beetles are able to reliably and accurately navigate the defined path, with a 73% success rate and 12-mm tracking error. Furthermore, an in-depth analysis of navigation performance suggests that limiting the number of consecutive unilateral stimulations would enhance the efficiency and reliability of the navigation. This study demonstrates that implementing burst stimulation can effectively reduce habituation, improving the reliability, accuracy, efficiency, and sustainability of the control system for terrestrial cyborg insects, advancing the feasibility for real-world deployment.","PeriodicalId":72764,"journal":{"name":"Cyborg and bionic systems (Washington, D.C.)","volume":"7 ","pages":"0537"},"PeriodicalIF":18.1,"publicationDate":"2026-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12968394/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147437609","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}

Here, we introduce a strategy that employs low-energy acoustic excitation of rising microbubbles to achieve scalable and efficient mass transfer across macroscale and microscale domains. By coupling buoyancy-driven convection with localized acoustic microstreaming, acoustic rising microbubbles simultaneously extend the operational workspace and intensify local mass transfer. Particle image velocimetry and computational fluid dynamics analyses characterize the distinct contributions of buoyancy-induced flows, acoustically induced microstreaming, and their superimposed effects. Various chemical and biomedical applications, including efficient high-viscosity mixing, accelerated chemical material synthesis, altered cell membrane permeability, promoted cell lysis, and thrombus clearance, demonstrate the great potential of the proposed acoustic rising bubbles for efficient mass transfer in laboratory and industrial liquid manipulations.","PeriodicalId":72764,"journal":{"name":"Cyborg and bionic systems (Washington, D.C.)","volume":"7 ","pages":"0449"},"PeriodicalIF":18.1,"publicationDate":"2026-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12968397/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147437243","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}

This physical intelligence enables our MTRG to merge both sensitivity and strength, showcasing a failure-to-triggering force ratio exceeding 2 orders of magnitude, which allows for customized responses to varying interaction requirements. This capability involves gentle triggering and robust grasping, analogous to the behavior exhibited by bats. To enable repeated operation, an integrated inflatable airbag is used to reset the bistable system, allowing for multiple grasping behaviors without manual intervention.

In this paper, we describe a framework that leverages bionic, wearable ECG sensor technologies along with multimodal large language models using a coherent temporal modeling effort to address the intertwining of fine-grained temporal dependencies, heterogeneous biomedical modalities, and interpretable risk stratification.

However, the domain bias issue in cross-domain applications remains a significant challenge in the practical implementation of BCI technology. This is particularly acute in scenarios where target data are unavailable, largely because of the noise sensitivity and acquisition limitations inherent in electroencephalography (EEG) signal data. When processing nonstationary EEG signals, existing domain generalization methods face limitations: Adversarial training may compromise model stability, while global feature alignment approaches struggle to sufficiently decouple category-dependent and category-independent features, thereby constraining generalization performance. Therefore, in this paper, we propose a hybrid approach based on domain-invariant feature learning and data enhancement. We introduce a \"fixed\" structure enhancement method that combines domain-invariant feature learning with data enhancement strategies, decouples domain-invariant features from other features, optimizes cross-domain feature extraction, and reduces the effect of noise in data.

When heated, the SMP softens to conform to surface irregularities; subsequent cooling restiffens it, enabling mechanical interlocking with surface asperities under vacuum. This synergistic design achieves robust, reversible, and cross-medium adhesion on challenging surfaces, both in air and underwater. The disc generated peak pull-off forces of 562 N in air and 590 N underwater on smooth substrates, over 850 times its own weight, and maintained strong adhesion even on rough surfaces (>707 μm) where conventional suction fails. Incorporating the SMP improved adhesion by 377% in air and 270% underwater compared to vacuum alone. Shear friction tests showed similar enhancements, and attachments remained secure for 26.8 h under load. The hybrid disc also enabled robotic demonstrations of gripping and cross-medium manipulation when mounted on a mechanical arm, highlighting its potential for real-world robotic applications.
