Electrochemical sensors are a promising tool for this type of task. A voltammetric sensor based on a combination of tin and cerium dioxide nanoparticles (SnO2\u2013CeO2 NPs) with surfactants has been developed for SY FCF determination. The synergetic effect of both types of NPs has been confirmed. Surfactants of various natures (sodium lauryl sulfate (SLS), Brij\u00ae 35, and hexadecylpyridinium bromide (HDPB)) have been tested as dispersive media. The best effects, i.e., the highest oxidation currents of SY FCF, have been observed in the case of HDPB. The sensor demonstrates a 4.5-fold-higher electroactive surface area and a 38-fold-higher electron transfer rate compared to the bare glassy carbon electrode (GCE). The electrooxidation of SY FCF is an irreversible, two-electron, diffusion-driven process involving proton transfer. In differential pulse mode in Britton\u2013Robinson buffer (BRB) pH 2.0, the sensor gives a linear response to SY FCF from 0.010 to 1.0 \u03bcM and from 1.0 to 100 \u03bcM with an 8.0 nM detection limit. The absence of an interferent effect from other typical food components and colorants has been shown. The sensor has been tested on soft drinks and validated with the standard chromatographic method.<\/jats:p>","DOI":"10.3390\/s24030930","type":"journal-article","created":{"date-parts":[[2024,1,31]],"date-time":"2024-01-31T10:44:24Z","timestamp":1706697864000},"page":"930","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["Voltammetric Sensor Based on the Combination of Tin and Cerium Dioxide Nanoparticles with Surfactants for Quantification of Sunset Yellow FCF"],"prefix":"10.3390","volume":"24","author":[{"given":"Liliya","family":"Gimadutdinova","sequence":"first","affiliation":[{"name":"Analytical Chemistry Department, Kazan Federal University, Kremleyevskaya 18, Kazan 420008, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8219-2813","authenticated-orcid":false,"given":"Guzel","family":"Ziyatdinova","sequence":"additional","affiliation":[{"name":"Analytical Chemistry Department, Kazan Federal University, Kremleyevskaya 18, Kazan 420008, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rustam","family":"Davletshin","sequence":"additional","affiliation":[{"name":"Department of High Molecular and Organoelement Compounds, Kazan Federal University, Kremleyevskaya 18, Kazan 420008, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,1,31]]},"reference":[{"key":"ref_1","unstructured":"Subburaj, M., and Faseela, P.M.
