Interaction of DHPC with DNA was used to explore its effect on DNA via Differential Pulse Voltammetry, Cyclic Voltammetry, and Electrochemical Impedance Spectroscopy. We demonstrated that oxidation signal of guanine bases of DNA decreased significantly while that of DHPC increased after its interaction with one another. Our candidate drug molecule exhibits LOD and LOQ, e.g., 1.5 mu g/mL and 4.9 mu g/mL, respectively. Toxicity effect value for DHPC (S%) was calculated as %31, demonstrating the candidate drug molecule's toxic effect on DNA.en10.1002/elan.202060597info:eu-repo/semantics/closedAccessDNAdrug moleculeDNA and drug interactionpyridinium derivativeelectrochemical biosensorDerivativesPyridiniumBiosensorsArticle33718191825Q3WOS:0006547488000012-s2.0-85106485222Q2
