A novel fluorescent sensing platform which employing NIR fluorescent Ag<sub>2</sub>S QDs and MnO<sub>2</sub> 2D nanosheets as NIR emitters and quenchers is designed for rapid and selective determination of glutathione (GSH). A facile and efficient approach was demonstrated for the synthesis of NIR fluorescent Ag<sub>2</sub>S QDs with the emission of 845 nm. Then the NIR fluorescent nanoprobe of Ag<sub>2</sub>S QDs-MnO<sub>2</sub> nanosheets is obtained by adsorbing Ag<sub>2</sub>S QDs onto the surface of MnO<sub>2</sub> nanosheets which have atomically thick two-dimensional structure and high specific surface area. And the NIR fluorescence of Ag<sub>2</sub>S QDs is quenched by the MnO<sub>2</sub> nanosheets. The presence of GSH could reduce MnO<sub>2</sub> to Mn<sup>2+</sup> that results in the restoration of NIR fluorescence for Ag<sub>2</sub>S QDs. The NIR fluorescent nanoprobe could be used for highly selective detection of GSH. Also a low detection limit of 60 μmol/L was obtained. Because NIR fluorescence of the Ag<sub>2</sub>S QDs can efficiently reduce the interferences from background scattering and autofluorescence. The NIR fluorescent nanoprobe was directly applied to monitor the GSH level in human serum sample with high accuracy and precision.","is_dataset_classified":null,"base_score":1.3862943611198906,"endowment":1.3862943611198906,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"33076088","pmcid":null,"openalex_id":"https://openalex.org/W33076088","authors":[],"funders":[{"funder_name":"NSFC","grant_id":"21705141","title":null},{"funder_name":"NSFC","grant_id":"21675140","title":null},{"funder_name":"NSFC","grant_id":"21575124","title":null},{"funder_name":"NSFC","grant_id":"21275124","title":null},{"funder_name":"NSFC","grant_id":"21275125","title":null},{"funder_name":"Natural Science Foundation of Jiangsu Province","grant_id":"BK20181219","title":null},{"funder_name":"Graduate Innovation Project Foundation of Jiangsu province","grant_id":"KYLX 1333","title":null},{"funder_name":"Graduate Innovation Project Foundation of Jiangsu province","grant_id":"KYLX 1334","title":null},{"funder_name":"Natural Science Research Projects of Jiangsu Higher Education","grant_id":"16KJB150044","title":null},{"funder_name":"PAPD","grant_id":"","title":null},{"funder_name":"Jiangsu Province","grant_id":"","title":null},{"funder_name":"Higher Education Outstanding Scientific and Technological Innovation Team of Jiangsu Province","grant_id":"","title":null},{"funder_name":"Yangzhou University","grant_id":"","title":null}],"total_grants":13,"fwci":0.0,"citation_percentile":0.02392027,"influential_citations":0,"citation_trend":[{"year":2014,"count":1},{"year":2017,"count":1},{"year":2022,"count":1}],"oa_status":"closed","license":"https://doi.org/10.15223/policy-004","oa_locations":[{"url":"https://api.elsevier.com/content/article/PII:S0039914020307669?httpAccept=text/xml","host_type":"publisher"},{"url":"https://api.elsevier.com/content/article/PII:S0039914020307669?httpAccept=text/plain","host_type":"publisher"},{"url":"https://dialnet.unirioja.es/servlet/articulo?codigo=4038096","host_type":"journal"}],"fields_of_study":["Regional Development and Innovation","Latin American Urban Studies","Glutathione","Humans","Manganese Compounds","Oxides","Quantum Dots","Silver"],"mesh_terms":["Humans","Oxides","Silver","Manganese Compounds","Glutathione","Quantum Dots"],"keywords":["Political science","Welfare economics","Geography","Humanities","Economy","Economics","Art","Glutathione","Human serum","Mno(2) Nanosheet","Ag(2)s Quantum Dot","Near−infrared Fluorescence"],"sdg_mappings":[{"sdg_number":0,"sdg_label":"Decent work and economic growth"}],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-08-03T08:43:35.214002Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
