Compared with lower metal atom utilization rate and catalytic activity of conventional nanocatalysts, single-metal atom catalysts (SACs) usually possess higher catalytic activity and selectivity owing to their well-defined structures and maximized atom utilization. Their properties are, however, strongly dependent on their composition and the preparation procedure. Here we describe the design, preparation and functionalization of SACs with single-metal atoms positioned within nitrogen-doped carbon supports. The SACs are prepared by pyrolysis of zeolitic imidazolate framework-8 (ZIF-8) or polydopamine-derived materials. Their properties depend on, for example, the metal chosen and atoms available for coordination; four example procedures are described: Cu-N<sub>4</sub> from Cu-ZIF-8, Ir-N<sub>5</sub> from Ir@ZIF-8 plus melamine, Co-PN<sub>3</sub> from triphenylphosphine@Co-ZIF-8 and Cu-SN<sub>3</sub> from ZnS@Cu-polydopamine. These SACs need to be functionalized to, for example, reduce aggregation and in vivo corona formation before they can be used in biological applications. In this Protocol, functionalization with the proteins (that is, cholesterol oxidase and pyruvate oxidase) is used as an example. The Protocol provides advice regarding physicochemical and functional characterization, as well as for performing experiments in tumor-bearing mice. The functional experiments were designed with the aim of identifying nanocatalysts with peroxidase-like activity that generate reactive oxygen species within areas of the tumor microenvironment that have increased levels of hydrogen peroxide. SAC synthesis takes 3-4 days, functional modification requires one extra day and the most basic and essential in vitro and in vivo assays require 2-3 months.</p>","PeriodicalId":18901,"journal":{"name":"Nature Protocols","volume":" ","pages":""},"PeriodicalIF":13.1,"publicationDate":"2025-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144336754","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we provide a protocol to identify immunogenic protein antigens expressed by commensal and pathogenic microbes by using bacteriophage (phage) display-mediated antibody/antigen biopanning. The procedure entails generation of an M13-phagemid library, production of an ORFeome (totality of open reading frames) phage library followed by multiple rounds of affinity-based immunoprecipitation and subsequent antigen validation by ELISA, ELISPOT and/or B cell tetramer generation. The protocol is optimized to identify antigens eliciting both IgA and IgG isotype responses and can use either circulating or intestinal antibodies for antigen identification. Generation and isolation of monoclonal phage encoding putative protein antigens enable simple identification of immunogenic antigens by Sanger sequencing, often providing protein domain-level resolution of epitope-bearing regions.

Models built on paleontological and paleoecological data can help to elucidate the factors influencing ecosystem health, stability, resilience and function, offering a unique perspective on the long-term ecological impacts of the ongoing human-induced biodiversity crisis and ecosystem degradation. Substantial advances have been made in quantifying the ecological dynamics and functional structures of paleocommunities. However, the effective reconstruction of paleo-food webs and the quantitative evaluation of paleocommunity dynamics are still challenging tasks. Here we present a detailed protocol for reconstructing paleo-food webs using fossil data and for modeling the stability and structures of these paleocommunities using the cascading extinction on graphs model. The procedure includes (1) selecting an appropriate geological time range and geographic scope, collecting fossil data and reconstructing paleocommunities; (2) assigning species to guilds on the basis of shared prey-predator relationships and connecting the guilds that interacted trophically; (3) measuring the functional structures and modeling their dynamics using species-level networks and cascading extinction on graphs models; and (4) analyzing the results to understand the community evolution and identify tipping points that predict ecosystem collapse. Organismal expertise is needed in the reconstruction of paleo-food webs. The resulting comparisons of the paleocommunity stability and structure can help calibrate the timing and patterns of ecological changes during critical intervals in Earth history. This Protocol aims to enhance the utilization of ecological modeling in understanding the evolution of ancient ecosystems. The time required for the protocol is community size dependent - for example, ~5 months for communities containing ~1,000 species.</p>","PeriodicalId":18901,"journal":{"name":"Nature Protocols","volume":" ","pages":""},"PeriodicalIF":13.1,"publicationDate":"2025-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144310154","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, their preparation remains challenging due to the particular gelation behavior displayed by metal systems. Here we detail the step-by-step instructions for the controlled synthesis of NMAs using salts, including reductive sodium borohydride and common salts such as sodium chloride. This strategy can rapidly synthesize NMAs with customizable ligament sizes (from <5 nm to >100 nm) and element distribution at room temperature (20-25 °C). The key stage of the approach is the control over the anisotropic assembly behavior of metal nanoparticles by tuning their interactions with ions/ligands. The synthesis conditions and procedures are elaborated to ensure reproducibility. We demonstrate the fabrication of seven single-component NMAs and over ten multicomponent NMAs, along with their corresponding characterizations and electrocatalytic applications. The fabrication period of noble metal hydrogels is 7-15 h, which can be shortened to a few minutes by introducing disturbances such as stirring.
