Examining the Effects of Applied Potential on the Surface Charge of Functionalized Monolayers for Site-Directed Ionic Self Assembly
… between immobilized polyelectrolytes and redox probes result in changes in electron transfer that can be monitored with electrochemical impedance measurements. Impedance measurements provide a qualitative assessment of the degree of potential-driven polyelectrolyte self assembly. The …

Nanocomposite immunosensor for anti-transglutaminase antibody
… from EIS data fitting) of [Fe (CN)6]3-/4- redox probe was used as the analytical parameter for measuring the interfacial kinetics which occurred as a result of the bio-recognition event (affinitive binding) between the tTG-antigen and anti-tTG antibody. Rct was found to increase with …

Nano- and micro- electrodes: applications in the biosensing field
… to several micrometers, respectively. Platinum probes with radius < 200 nm were employed in high resolution SECM imaging of an array of nanocavities (600–700 nm wide and 400-500 nm deep) prepared by means of nanosphere lithography. The small size of the probe employed in the study allowed …

Green Carbon Quantum Dots Based Electrochemical Sensors for Analysis of Neurotransmitters
… 5 mM ferricyanide/ferrocyanide ([Fe(CN)6]3-/4-) redox probe were used for electrochemical characterization. The EIS data showed that the composites have lower charge transfer resistance than the individual nanomaterials. The superior electronic properties of the composite relative to the …

Localization of metal ions in DNA
… The effectiveness of using the IrCl62-/3- redox couple to investigate DNA monolayers and the potential advantages of this system over the standard Fe(CN)63-/4- redox couple are demonstrated. B-DNA monolayers were converted to M-DNA by incubation in buffer containing 0.4 mM Zn2+ at pH 8.6 …
