The competition occurs between the free KA/QA standards and BSA-conjugated antigens for a fixed amount of primary antibody binding sites. This affects the electron transfer rate of the [Fe(CN)6]3−/4− redox couple and changes the charge transfer resistance (Rct) on the electrode surface. The impedimetric signal measured due to the change in Rct is then correlated to the KA and QA concentration.","is_dataset_classified":null,"base_score":0.6931471805599453,"endowment":0.6931471805599453,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"19767382","pmcid":null,"openalex_id":"https://openalex.org/W4387978980","authors":[],"funders":[{"funder_name":"Ministry of Education (MOE) Singapore","grant_id":"RG88/20","title":null},{"funder_name":"Ministry of Education (MOE) Singapore","grant_id":"19-26910X","title":null}],"total_grants":2,"fwci":1.3436,"citation_percentile":0.81766663,"influential_citations":0,"citation_trend":[{"year":2024,"count":1}],"oa_status":"gold","license":"cc-by","oa_locations":[{"url":"https://www.mdpi.com/2673-4591/48/1/45/pdf?version=1698383741","host_type":""},{"url":"https://www.mdpi.com/2673-4591/48/1/45/pdf?version=1698383741","host_type":""},{"url":"https://www.mdpi.com/2673-4591/48/1/45/pdf","host_type":"publisher"},{"url":"https://doi.org/10.3390/csac2023-14903","host_type":""},{"url":"https://doaj.org/article/1c599132a9ff4f8098cdb17d769c9637","host_type":"repository"},{"url":"https://doi.org/10.3390/CSAC2023-14903","host_type":"repository"}],"fields_of_study":["Advanced biosensing and bioanalysis techniques","Electrochemical Analysis and Applications","Molecular Junctions and Nanostructures"],"mesh_terms":[],"keywords":["Chemistry","Electron transfer","Electrode","Electrochemistry","Conjugated system","Biosensor","Ohmic contact","Cyclic voltammetry","Metabolite","Ursolic acid","Biophysics","Biochemistry","Chromatography","Photochemistry","Organic chemistry","Polymer","Physical chemistry","Biology"],"sdg_mappings":[],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-08-04T13:19:00.129446Z","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":[]}
