Herein, a hydrothermal approach is used to synthesize the composite of ytterbium zinc oxide endorsed on 2D hexagonal boron nitride (YbZnO@h\u2010BN). Different analytical methods, including Fourier transform infrared (FTIR), Raman spectroscopy, field emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM), and X\u2010ray diffraction (XRD), along with X\u2010ray photoelectron spectroscopy (XPS), are used to interrogate the morphological and structural characteristics of the nanocomposite. FTIR analysis reveals Zn\u2013O and Yb\u2013O functionality, while SEM images shows\u00a0the YbZnO@h\u2010BN microspherical structure. Cyclic voltammetry (CV) and square\u2010wave voltammetry (SWV) techniques are employed for the electrochemical analysis of Ciprofloxacin (CIP) on the YbZnO@h\u2010BN\/glassy carbon electrode (GCE)\u2010modified electrode. The YbZnO@h\u2010BN\/GCE sensor demonstrates a broad linear range (0.05\u2009\u03bcM to 100\u2009\u03bcM) with a lower limit of detection (0.059 \u03bcM) and high sensitivity of 7.4441\u2009\u03bcA\u2009\u03bcM\n                    <jats:sup>\u22121<\/jats:sup>\n                    \u2009cm\n                    <jats:sup>\u22122<\/jats:sup>\n                    under optimal conditions. Additionally, the sensor shows good responsiveness for CIP, along with notable reproducibility, stability, and selectivity. Furthermore, the genuine real wastewater sample and commercial CIP tablet are utilized to investigate the usefulness of the proposed YbZnO@h\u2010BN\/GCE sensor for CIP detection in real practice, revealing satisfactory recovery values of 94 to 105% and 95 to 112%, respectively.\n                  <\/jats:p>","DOI":"10.1002\/open.202500246","type":"journal-article","created":{"date-parts":[[2025,6,26]],"date-time":"2025-06-26T03:08:39Z","timestamp":1750907319000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Ytterbium\u2013Zinc Oxide Embedded on Hexagonal Boron Nitride Nanocomposite for Electro\u2010Oxidation of Ciprofloxacin"],"prefix":"10.1002","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8881-7618","authenticated-orcid":false,"given":"Collen","family":"Nepfumbada","sequence":"first","affiliation":[{"name":"College of Science, Engineering and Technology (CSET) University of South Africa (UNISA) Institute for nanotechnology and water sustainability (iNanoWS)  Florida campus Johannesburg 1709 South Africa"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christopher P.","family":"Woodley","sequence":"additional","affiliation":[{"name":"Department of Chemistry University of Michigan  Ann Arbor Michigan 48109\u20101055 United States"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2534-2579","authenticated-orcid":false,"given":"Bhekie B.","family":"Mamba","sequence":"additional","affiliation":[{"name":"College of Science, Engineering and Technology (CSET) University of South Africa (UNISA) Institute for nanotechnology and water sustainability (iNanoWS)  Florida campus Johannesburg 1709 South Africa"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8298-5963","authenticated-orcid":false,"given":"Bart M.","family":"Bartlett","sequence":"additional","affiliation":[{"name":"College of Science, Engineering and Technology (CSET) University of South Africa (UNISA) Institute for nanotechnology and water sustainability (iNanoWS)  Florida campus Johannesburg 1709 South Africa"},{"name":"Department of Chemistry University of Michigan  Ann Arbor Michigan 48109\u20101055 United States"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1423-3484","authenticated-orcid":false,"given":"Usisipho","family":"Feleni","sequence":"additional","affiliation":[{"name":"College of Science, Engineering and Technology (CSET) University of South Africa (UNISA) Institute for nanotechnology and water sustainability (iNanoWS)  Florida campus Johannesburg 1709 South Africa"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,6,26]]},"reference":[{"key":"e_1_2_9_2_1","first-page":"1","volume":"12","author":"Mach\u00edn A.","year":"2022","journal-title":"Catalysts"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.scitotenv.2017.12.008"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.1039\/D3SD00129F"},{"key":"e_1_2_9_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jhazmat.2019.121304"},{"key":"e_1_2_9_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.fm.2017.11.011"},{"key":"e_1_2_9_7_1","doi-asserted-by":"publisher","DOI":"10.1007\/s11356-023-30223-2"},{"key":"e_1_2_9_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.watres.2018.08.042"},{"key":"e_1_2_9_9_1","doi-asserted-by":"publisher","DOI":"10.3390\/chemosensors11020091"},{"key":"e_1_2_9_10_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.saa.2015.12.011"},{"key":"e_1_2_9_11_1","first-page":"1","volume":"59","author":"Mahmoud T.
