Coined just over a decade ago, metal-phenolic networks (MPNs) have emerged as broad and powerful platforms, demonstrating great potential in cancer therapy, with broad success achieved in animal models. MPNs are characterized by the network's formation via phenolic ligands and metal ion coordination and serve as versatile drug delivery platforms. Moreover, MPNs not only inherit the inherent pharmacological properties of the building blocks but also acquire new functions during their assembly, including pH responsiveness, photothermal conversion, and redox activity. This review explores the latest advancements and design principles of MPNs in cancer therapy. First, we introduce the building blocks and formation of MPNs and analyze their unique properties and functions. Second, we comprehensively describe various strategies of MPNs in tumor treatment and discuss their potential as a multifunctional treatment platform. Finally, we outline our perspective on the key challenges in translating MPNs to the clinic, with the intention of stimulating the initiation of MPNs-based anti-cancer trials.</p>\u0000 </div>","PeriodicalId":7803,"journal":{"name":"Angewandte Chemie","volume":"138 43","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149219522","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}

Here, we report a polymer-free, aqueous-based approach in which betaine, a naturally occurring zwitterion, is intercalated into bentonite clay galleries through ionic interactions between its cationic trimethylammonium group and the negatively charged clay surface. This intercalation bridges the clay galleries, creating ion-conductive pathways within free-standing, mechanically robust membranes, as confirmed by molecular dynamics simulations, rheo-impedance, and electrochemical impedance spectroscopy. Incorporation of transition-metal ions (Fe<sup>3</sup><sup>+</sup>, Mn<sup>2</sup><sup>+</sup>) introduces redox-active sites that contribute to pseudocapacitive charge storage.

The proposed EU REACH restriction uses total fluorine (TF), extractable or adsorbable organic fluorine (EOF/AOF), targeted PFAS analysis, and non-target analysis as complementary lines of evidence. We argue that these approaches are valuable, but they do not measure the same chemical quantity. While TF is a useful conservative gatekeeper for fluorinated materials, it cannot distinguish between polymeric PFASs, inorganic fluorine, volatile precursors, or fluorinated substances that may or may not fall within broad PFAS definitions. This limitation is especially important for polymeric PFASs, including both backbone fluoropolymers and side-chain fluorinated polymers, which can be non-extractable, particulate, or transformable into mobile precursors such as fluorotelomer alcohols. We propose an analytical decision tree that separates bulk fluorine screening, extractable fractions, volatile and semi-volatile PFASs, polymeric and particulate PFASs, and structurally confirmed molecular PFASs. Such an operational framework would preserve the regulatory value of fluorine screening while avoiding overinterpretation of any single metric as “PFAS content”.

This review synthesizes current advances aimed at enhancing the specificity of CRISPR diagnostics, with particular emphasis on the pivotal role of CRISPR RNA (crRNA) engineering. We detail how structural determinants of crRNA, including spacer length optimization, intentional mismatch design, secondary-structure modulation, chemical modification, strand-displacement gating, and synergistic design frameworks, govern CRISPR-mediated target recognition and define the energetic and kinetic thresholds for accurate cleavage. Key engineering strategies encompassing computational prediction and modeling, high-throughput screening, and hybrid guide architectures are systematically examined for their capacity to elevate single-nucleotide discrimination, stabilize reaction performance, and enable robust multiplexed detection for pathogen profiling and mutation identification. Despite rapid progress, outstanding challenges persist, including interference from complex clinical matrices, lack of unified evaluation standards, and scalability barriers that hinder clinical translation. Addressing these limitations through integrated crRNA design, system-level optimization, and standardized benchmarking will be essential for realizing the promise of CRISPR diagnostics.

However, the sluggish defect-repair kinetics in traditional solid-phase routes remains mechanistically unclear, limiting the practical deployment of this technology. Here, theoretical calculations reveal that the phonon localization in defect-rich S-LFP is the essential factor responsible for the sluggish defect-repair kinetics. Localized phonons retard thermal diffusion, hindering the energy available to overcome defect repair barriers, and concurrently intensify electron-phonon coupling that suppresses the electron migration necessary for the reduction of Fe(III). Guided by this insight, we employ electric/thermal coupling field strategy to repair the S-LFP cathode. Carriers driven by the electric field transfer energy to phonons through electron-phonon scattering, which promotes energy redistribution across disparate phonon modes, collectively enhancing phonon delocalization. As a result, Li-Fe antisites (Fe<sub>Li</sub>) were repaired within 5 s at 700°C, and the complete structural repair and lithiation are achieved within 60 s. Experimental results indicate that the regenerated cathode delivers a discharge specific capacity of 151.2 mAh g<sup>−1</sup> at 0.1C, and exhibits a capacity retention of 84.3% after 1100 cycles at 1 C.
