The Cr2O3-GA2 suspension used in electrode modification was physically coated on the BDD electrode by a simple drop-casting method. Characterization of Cr2O3-GA2 used in the modification was made by scanning electron microscopy, energy-dispersive spectroscopy (SEM-EDS), and the electrochemical method. The behavior of gentamicin sulfate on Cr2O3-GA2/BDDE was studied by cyclic voltammetry (CV), and its electrochemical analysis was done by differential pulse voltammetry (DPV). Electrochemical analysis of gentamicin sulfate on Cr2O3-GA2/BDDE was carried out in a pH 9 Britton–Robinson (BR) buffer by the DPV method. The linear working range of gentamicin sulfate on Cr2O3-GA2/BDDE was calculated as 5.96 × 10−6−6.54 × 10−5mol L−1, and the correlation coefficient was calculated as 0.997. The limit of detection (LOD) was found to be 2.84 × 10−6. mol L−1. Additionally, Genta, a 3% eye/ear drop solution, was preferred to determine the applicability of gentamicin sulfate in a commercial formulation. As a result, it was shown that the method developed on Cr2O3-GA2/BDDE for the determination of gentamicin sulfate can be applied to commercial drugs.</dc:description><dc:publisher>John Wiley and Sons Inc</dc:publisher><dc:date>2026</dc:date><dc:type>Article</dc:type><dc:identifier>https://rdlopen.rawdatalibrary.net/r/munzur/977</dc:identifier><dc:identifier>https://doi.org/10.1002/slct.202507118</dc:identifier><dc:identifier>2365-6549</dc:identifier><dc:language>en</dc:language><dc:relation>ChemistrySelect</dc:relation><dc:rights>info:eu-repo/semantics/closedAccess</dc:rights><dc:type>info:eu-repo/semantics/article</dc:type><dc:identifier>https://munzur-rdlopen.rawdatalibrary.net/tr/items/munzur/977</dc:identifier></oai_dc:dc></metadata></record></GetRecord></OAI-PMH>
