Fabrication of an electrochemical sensor based on carbon nanotubes modified with gold nanoparticles for determination of valrubicin as a chemotherapy drug: Valrubicin-DNA interaction

A screen printed carbon electrode modified with carbon nanotubes and gold nanoparticles as a sensitive electrochemical sensor for determination of thiamphenicol residue in milk

“…8,9 Commonly, gold nanoparticles (AuNPs) are being used as a kind of nanomaterial for fabrication of nanocomposites and enhancement of sensitivity in electrochemical sensors because of excellent catalytic and conductivity properties. 10 A nanocomposite of AuNP/CNTs is of particular interest owing to its easy fabrication process and wide potential application, moreover, it combines the excellent physicochemical properties of AuNPs and CNTs, 11 which have been reported in several studies for electrochemical analysis. [12][13][14] In general, AuNPs are decorated on the surface of CNTs by either a direct or indirect deposition process.…”

“…It seems that by increasing the pH from 3 to 6, the adsorption process becomes predominant. 10,11 As a result, pH 6.0 was chosen as the optimum pH for the electrochemical oxidation of TAP. The plot of E p Fig.…”

Potentiometric sensor fabrication having 2D sarcosine memories and analytical features

“…Electrochemical sensors in the analysis of biological sample have been developed due to their simplicity, reasonable accuracy and precision, low cost, and rapidity [8][9][10][11][12][13][14]. There is no need for derivatization or time-consuming extraction steps in comparison with other techniques because electroanalytical methods are less sensitive to the matrix effects.…”

A Novel Platform Based on Au−CeO2@MWCNT Functionalized Glassy Carbon Microspheres for Voltammetric Sensing of Valrubicin as Bladder Anticancer Drug and its Interaction with DNA

“…Taking into consideration the importance of this anticancer drug in various areas, the development of an electrochemical sensor for the determination of VLB as a chemotherapy medicine and its interaction with DNA is highly required. Hitherto, there is only one report for the analytical determination of VLB studied by Hajian et al, which was based on the adsorption and reduction of VLB at an electrochemical sensor constructing from gold nanoparticles and multiwall carbon nanotubes [7]. The LOD was 0.018 μM in pH 4.0 by using cyclic voltammetry.…”
