Over the years, it has raised severe concern as a potential hazard to the human endocrine system and the environment. Developing robust and easy-to-use sensors for bisphenol A is important in various areas, such as controlling and monitoring water purification and sewage water systems, food safety monitoring, etc. Here, we report an electrochemical method to fabricate a bisphenol A (BPA) sensor based on a modified Au nanoparticles\/multiwalled carbon nanotubes composite electrocatalyst electrode (AuCu-UPD\/MWCNTs\/GCE). Firstly, the Au-Cu alloy was prepared via a convenient and controllable Cu underpotential\/bulk Au co-electrodeposition on a multiwalled modified carbon nanotubes glassy carbon electrode (GCE). Then, the AuCu-UPD\/MWCNTs\/GCE was obtained via the electrochemical anodic stripping of Cu underpotential deposition (UPD). Our novel prepared sensor enables the high-electrocatalytic and high-performance sensing of BPA. Under optimal conditions, the modified electrode showed a two-segment linear response from 0.01 to 1 \u00b5M and 1 to 20 \u00b5M with a limit of detection (LOD) of 2.43 nM based on differential pulse voltammetry (DPV). Determination of BPA in real water samples using AuCu-UPD\/MWCNTs\/GCE yielded satisfactory results. The proposed electrochemical sensor is promising for the development of a simple, low-cost water quality monitoring system for the detection of BPA in ambient water samples.<\/jats:p>","DOI":"10.3390\/molecules28248036","type":"journal-article","created":{"date-parts":[[2023,12,11]],"date-time":"2023-12-11T14:12:51Z","timestamp":1702303971000},"page":"8036","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Preparation of Gold Nanoparticles via Anodic Stripping of Copper Underpotential Deposition in Bulk Gold Electrodeposition for High-Performance Electrochemical Sensing of Bisphenol A"],"prefix":"10.3390","volume":"28","author":[{"given":"Zhao","family":"Huang","sequence":"first","affiliation":[{"name":"Hunan Key Laboratory of Biomedical Nanomaterials and Devices, College of Life Sciences and Chemistry, Hunan University of Technology, Zhuzhou 412007, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zihan","family":"Chen","sequence":"additional","affiliation":[{"name":"Hunan Key Laboratory of Biomedical Nanomaterials and Devices, College of Life Sciences and Chemistry, Hunan University of Technology, Zhuzhou 412007, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dexuan","family":"Yan","sequence":"additional","affiliation":[{"name":"Hunan Key Laboratory of Biomedical Nanomaterials and Devices, College of Life Sciences and Chemistry, Hunan University of Technology, Zhuzhou 412007, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shuo","family":"Jiang","sequence":"additional","affiliation":[{"name":"Hunan Key Laboratory of Biomedical Nanomaterials and Devices, College of Life Sciences and Chemistry, Hunan University of Technology, Zhuzhou 412007, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Libo","family":"Nie","sequence":"additional","affiliation":[{"name":"Hunan Key Laboratory of Biomedical Nanomaterials and Devices, College of Life Sciences and Chemistry, Hunan University of Technology, Zhuzhou 412007, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xinman","family":"Tu","sequence":"additional","affiliation":[{"name":"Key Laboratory of Jiangxi Province for Persistent Pollutants Control and Resources Recycle, Nanchang Hangkong University, Nanchang 330063, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xueen","family":"Jia","sequence":"additional","affiliation":[{"name":"Hunan Key Laboratory of Biomedical Nanomaterials and Devices, College of Life Sciences and Chemistry, Hunan University of Technology, Zhuzhou 412007, China"},{"name":"Department of Physics, Ume\u00e5 University, SE-901 87 Ume\u00e5, Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thomas","family":"W\u00e5gberg","sequence":"additional","affiliation":[{"name":"Department of Physics, Ume\u00e5 University, SE-901 87 Ume\u00e5, Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0767-5997","authenticated-orcid":false,"given":"Long","family":"Chao","sequence":"additional","affiliation":[{"name":"Hunan Key Laboratory of Biomedical Nanomaterials and Devices, College of Life Sciences and Chemistry, Hunan University of Technology, Zhuzhou 412007, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,12,11]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"5438","DOI":"10.1021\/acs.est.5b05387","article-title":"Bisphenol analogues other than BPA: Environmental occurrence, human exposure, and toxicity\u2014A review","volume":"50","author":"Chen","year":"2016","journal-title":"Environ.
