“…The XRD peaks of FGCM were not observed in the AuÀ CeO 2 @MWCNT-OH/FGCM hybrid composite. These may be due to the high degree of AuÀ CeO 2 NPs deposition at MWCNT-OH/FGCM [39]. Moreover, the TEM investigated the surface features of FGCM and Au/ CeO 2 @FGCM hybrid composite.…”

In this work, a sensitive and simple electrochemical sensor was constructed for the quantitative analysis of valrubicin (VLB), as a chemotherapy drug, in biological samples based on MWCNTs-OH, CeO 2 NPs, AuNPs and functionalized glassy carbon microspheres (FGCM) modified electrode (AuÀ CeO 2 @MWCNT-OH/ FGCME). The new nanocomposite AuÀ CeO 2 @MWCNT-OH/FGCM produced an electrocatalytic effect towards the electrochemical oxidation of VLB. The electrochemical behavior of the AuÀ CeO 2 @MWCNT-OH/FGCME was also investigated using EIS and CV. The experimental and operation parameters that affect the sensitivity of the sensor were optimized. SWV was utilized for the electrochemical analysis of VLB. The oxidation peak currents were linearly dependent on the concentration of VLB in the range of 7.10 × 10 À 8 M to 5.8 × 10 À 7 M. The detection limit of VLB was found to be 1.56 × 10 À 9 M which was more sensitive than the reported method. The possible coexistence biological matrix had no interference effect on the determination of VLB. The fabricated sensor was also effectively employed to the sensitive detection of VLB in human body fluids. The interaction of VLB with salmon testes and calf thymus double-stranded DNA (st-DNA and ct-DNA) on AuÀ CeO 2 @MWCNT-OH/ FGCME has been further studied by cyclic voltammetry. The corresponding binding constant (K), surface concentration (Γ) and Gibbs free energy (ΔG°) were computed for the free VLB and the bound VLB-dsDNA complex. The obtained results revealed that VLB binds to DNA with a high binding constant as well as the K value for VLB-st-DNA (K = 1.81 × 10 5 M À 1) is higher than that of VLB-ct-DNA (K = 4.99 × 10 4 M À 1).
