“…3 In addition to potential therapeutic applications, due to the electrochemical behavior of many drugs, DNA binding studies are anticipated to be useful in electroanalytical applications. [4][5][6][7] There are mainly three possible binding modes between DNA and small molecules: (1) An electrostatic interaction that extends the negatively charged phosphates outside the DNA double helix; (2) the interaction with grooves of DNA; and (3) an intercalation model in which the base pairs of DNA unwind to accommodate an intercalating agent. 8,9 Several techniques have been employed to study the binding of small molecules to DNA including, for example, viscometry, 10 UV-Vis spectroscopy, 11 isothermal calorimetric titration, 12 luminescence, 13 electrophoresis, 14 fluorescence 15 and electroanalytical methods.…”

“…4 In addition to potential therapeutic applications, due to the redox activity of many drugs, DNA binding studies are anticipated to be useful in electroanalytical applications. [5][6][7][8] Various techniques have been extensively employed to study the binding of drug molecules to DNA, such as spectroscopic methods, 9,10 viscometry, 11 isothermal calorimetric titration, 12 luminescence, 13 electrophoresis, 14 fluorescence, 15 nuclear magnetic resonance, 16 quartz crystal microgravimetry 17 and electroanalytical methods. [18][19][20][21][22][23] Since many small molecules exhibit redox activity, the electrochemical method should provide a useful complement to the previously used methods for investigations.…”
