The electrocatalytic performance of the electrode was tested using various electrochemical methods such as amperometry and cyclic voltammetry (CV). The NiNPs@Co3O4\/GO-COOH\/GC electrode showed noticeably superior electrocatalytic behavior for glucose oxidation in 0.1 M NaOH media, ascribed to the good synergistic impact between NiNPs, Co3O4, and GO-COOH. The amperometric response of the NiNPs@Co3O4\/GO-COOH\/GC electrode to glucose exhibited two linear determination ranges at +0.55 V potential. The first one was between 4.8 \u00d7 10\u22127 and 9.5 \u00d7 10\u22124 M and the second one was between 9.5 \u00d7 10\u22124 and 4.87 \u00d7 10\u20133 M. The limit of detection was 1.4 \u00d7 10\u20137 M dependent upon a signal-to-noise ratio of 3. The sensor displayed good performance factors such as selectivity, reproducibility, and stability. Furthermore, the suitability of the sensor for detecting glucose in biological fluids proved satisfactory.<\/jats:p>","DOI":"10.55730\/1300-0527.3801","type":"journal-article","created":{"date-parts":[[2026,6,26]],"date-time":"2026-06-26T05:07:47Z","timestamp":1782450467000},"page":"327-340","source":"Crossref","is-referenced-by-count":0,"title":["A nonenzymatic electrochemical glucose sensor depending on a NiNPs\/Co3O4\/functionalized graphene oxide-modified working electrode"],"prefix":"10.55730","volume":"50","author":[{"given":"S\u00dcMEYRA","family":"PEKMEZ","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"MUHAMMET","family":"G\u00dcLER","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"34691","published-online":{"date-parts":[[2026,6,18]]},"container-title":["Turkish Journal of Chemistry"],"original-title":[],"language":"en","deposited":{"date-parts":[[2026,10,21]],"date-time":"2026-10-21T12:52:47Z","timestamp":1792587167000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.tubitak.gov.tr\/chem\/vol50\/iss3\/9"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,6,18]]},"references-count":0,"journal-issue":{"issue":"3","published-online":{"date-parts":[[2026,6,18]]}},"URL":"https:\/\/doi.org\/10.55730\/1300-0527.3801","relation":{},"ISSN":["1300-0527"],"issn-type":[{"value":"1300-0527","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,6,18]]}}}
