However, their limited ovarian targeting capacity and inefficient mitochondrial delivery have substantially constrained their therapeutic efficacy. Here, we present a biomimetic, dual-targeted EV platform derived from <i>Lycium barbarum</i> (TPP-GCM-LBEVs) and demonstrate its therapeutic potential in a mouse POI model. Hybridization with granulosa cell membranes (GCMs) confers intrinsic ovarian-homing capability, whereas subsequent surface conjugation with triphenylphosphonium (TPP) promotes mitochondrial targeting following cellular uptake. TPP-GCM-LBEVs efficiently target granulosa cells and their mitochondria <i>in vitro</i> and <i>in vivo</i>, with cellular internalization mediated predominantly by caveolae- and lipid-raft-dependent endocytosis. Subsequently, TPP-GCM-LBEVs restore mitochondrial ultrastructure and bioenergetic function in granulosa cells, thereby re-establishing ovarian redox and metabolic homeostasis. This mitochondrial rescue enhances the paracrine metabolic support provided to oocytes, thereby improving oocyte quality and developmental competence. Consistent with these effects, treatment with TPP-GCM-LBEVs rescues follicular development, ovarian endocrine function, and natural fertility in POI mice. Collectively, this cross-species, dual-targeted, plant-derived EV strategy provides a translatable and effective therapeutic framework for POI, with broader implications for mitochondria-associated reproductive ageing.</p>","PeriodicalId":87,"journal":{"name":"Materials Horizons","volume":" ","pages":"10207-10221"},"PeriodicalIF":11.4,"publicationDate":"2026-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148910339","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}

Upon static melting, an unusual conformationally ordered orthorhombic phase is retained in the melts of less-crosslinked meso-granules and physically intra-crosslinked meso-fibrils of as-polymerized nascent powders up to a universal order-disorder transition temperature (<i>T</i>_O-D) of approximately 190 °C, after which it transformed into a disorder globular melt.

However, its overall environmental sustainability depends not only on the renewable nature of biomass feedstocks but also on greenhouse gas emissions generated throughout production, utilization, regeneration, and end-of-life management. This review critically reviews the carbon footprint of biomass-derived activated carbon from a life cycle perspective, emphasizing the influence of feedstock selection, production technologies, activation methods, transportation, energy consumption, and chemical utilization on environmental performance. The application of life cycle assessment (LCA) and carbon accounting frameworks for quantifying greenhouse gas emissions, identifying environmental hotspots, and evaluating carbon-negative potential is comprehensively discussed. Comparative analyses of diverse biomass feedstocks and recent experimental studies demonstrate that agricultural residues generally exhibit lower environmental burdens than fossil-derived precursors, although sustainability remains highly dependent on process design, regional energy systems, and methodological assumptions. Emerging applications in water purification, air pollution control, carbon dioxide capture, catalysis, energy storage, hydrogen storage, and soil carbon sequestration further illustrate the multifunctional role of biomass-derived activated carbon in sustainable development.

The Ce(III,IV)-MOF was employed both as a scaffold for Ru(bpy)₃²⁺ and as a co-reaction catalyst. The three-dimensional structure of the Ce(III,IV)-MOF provides a stable environment for Ru(bpy)₃²⁺, while the Ce(III)/Ce(IV) redox pair within the framework facilitates TPrA oxidation through reversible single-electron transfer, thereby enhancing TPrA˙ generation.
