A facile electrochemical sensor for olivetol was fabricated based on p-L-serine, and copper oxide (CuO) nanoparticles modified carbon paste electrode (p-L-serine\/CuO\/CPE). The proposed p-L-serine\/CuO\/CPE was applied to the electrochemical detection of olivetol by cyclic voltammetry (CV) and differential pulse voltammetric (DPV). Through the characterizations of materials and modified electrodes, the p-L-serine\/CuO\/CPE exhibited enhanced electrochemical signals for olivetol compared to bare CPE and CuO\/CPE in both CV and DPV methods. Under the optimized conditions, the proposed p-L-serine\/CuO\/CPE showed a good quantitative analysis ability and a wide analysis range from 20 to 100 \u03bcmol L\u22121 of olivetol with a limit of detection of 1.04 \u03bcmol L\u22121. Based on the reproducibility, repeatability, and stability exhibited by this fabricated sensor and the cheap and accessible raw materials, the p-L-serine\/CuO\/CPE became a novel determination choice for olivetol in the electrochemical method with the advantages of being cost-effective and convenient.<\/jats:p>","DOI":"10.3390\/nano13010070","type":"journal-article","created":{"date-parts":[[2022,12,27]],"date-time":"2022-12-27T07:30:06Z","timestamp":1672126206000},"page":"70","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Electrochemical Detection of Olivetol Based on Poly(L-Serine) Film Layered Copper Oxide Modified Carbon Paste Electrode (p-L-Serine\/CuO\/CPE)"],"prefix":"10.3390","volume":"13","author":[{"given":"Zongyi","family":"You","sequence":"first","affiliation":[{"name":"Institute of Bast Fiber Crops, Chinese Academy of Agricultural Sciences, Changsha 410205, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yi","family":"Zhang","sequence":"additional","affiliation":[{"name":"Institute of Bast Fiber Crops, Chinese Academy of Agricultural Sciences, Changsha 410205, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shengwen","family":"Duan","sequence":"additional","affiliation":[{"name":"Institute of Bast Fiber Crops, Chinese Academy of Agricultural Sciences, Changsha 410205, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5597-6789","authenticated-orcid":false,"given":"Liangliang","family":"Liu","sequence":"additional","affiliation":[{"name":"Institute of Bast Fiber Crops, Chinese Academy of Agricultural Sciences, Changsha 410205, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,12,23]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Taslimi, P., and Gul\u00e7in, \u0130.
