Here, we introduce a ligand-mediated acid-activatable MPI probe (LAMP) composed of magnetic nanoparticles linked via acid-sensitive imine bond-containing ligands. The LAMP exhibits stable assembly in neutral conditions and rapid disassembly in acidic microenvironments. The imine bond crosslinking promotes a compact structure that enhances magnetic dipole interactions, significantly quenching the initial MPI signal. Upon exposure to acidic conditions, the probe disassembles, restoring the MPI signal in a highly controlled, environment-dependent manner. This switchable assembly enables precise, real-time imaging of acidity-associated diseases such as sepsis progression. Our findings demonstrate that the ligand-mediated modulation of magnetic dipole interactions provides a versatile platform for the design of next-generation MPI probes for biomarker-specific MPI imaging.","PeriodicalId":388,"journal":{"name":"Matter","volume":"74 1","pages":""},"PeriodicalIF":18.9,"publicationDate":"2025-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143020944","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}

These analogs are intended to improve fundamental understanding of biomatter plastics. Spectroscopic analyses of biomatter analogs suggest that cohesion depends on protein aggregation during thermomechanical processing. Molecular dynamics simulations confirm that alterations to protein conformation and hydrogen bonding are likely the primary mechanisms underlying the formation of a cohesive, proteinaceous matrix.

Achieving superior resistance to both simultaneously is difficult due to microbial and acid-induced corrosion in wastewater alongside hydrogen embrittlement caused by the generation of free hydrogen during corrosion. These complex loading scenarios require materials capable of withstanding both forms of degradation. Here, we present a FeCoMnNiCu alloy, designed using the multiprincipal element concept, which forms a protective passive film and exhibits high resistance to both microbial and oxidative acid-induced corrosion. Furthermore, it shows exceptional resistance to hydrogen embrittlement with a hydrogen embrittlement index of approximately 4.01%. This is achievable because the alloy has a very low hydrogen diffusion coefficient and promotes hydrogen-induced twinning through the reduction of stacking fault energy. These properties establish the new alloy as a promising solution for components exposed to corrosive, hydrogen-rich municipal wastewater environments.","PeriodicalId":388,"journal":{"name":"Matter","volume":"14 1","pages":""},"PeriodicalIF":18.9,"publicationDate":"2025-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142939646","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}
