A redox mediator is a hyperbranched polymer having redox moieties (e.g. ferrocene) incorporated into its structure and/or chemically bonded to its periphery. It is attached to an electrode and assists in transferring electrons between the electrode and a redox enzyme.

How does alloying help to reduce corrosion?

Corrosion is a chemical reaction that weakens a metal. It is a redox reaction, to be exact. By creating an alloy, new atoms (or different rations of atoms) are added in the metal being made, which changes the structure of the metal. This can form stronger bonds, which can be resistant to the redox corrosion reaction.Note: Alloys can be made that have a worse resistance to such reactions, but there is no market for them, so they are not sold.


Mixed potential theory?

is a theory used in electrochemistry that relates the potentials and currents from differing constituents to come up with a 'weighted' potential at zero net current. In other words, it is an electrode potential resulting from a simultaneous action of more than a single redox couple, while the net electrode current is zero.


Cathode and anode in cyclic voltammetry?

In cyclic voltammetry, the cathode and anode are the two electrodes involved in redox reactions. The cathode is where reduction occurs, meaning it gains electrons, while the anode is where oxidation takes place, losing electrons. The potential of these electrodes is varied cyclically, allowing for the measurement of current responses that provide insight into the electrochemical properties of the analyte. This technique is widely used for studying reaction mechanisms, kinetics, and thermodynamics in electrochemistry.


Why HMP shunt called as shunt?

The HMP shunt, or Hexose Monophosphate shunt, is referred to as a "shunt" because it diverts glucose-6-phosphate from the glycolytic pathway to generate NADPH and ribose-5-phosphate. This pathway provides essential reducing power for biosynthetic reactions and helps in maintaining cellular redox balance. The term "shunt" highlights its role in redirecting metabolic flow away from energy production towards biosynthetic and antioxidant functions.


Is excitation voltammetry and amperometry same thing?

Excitation voltammetry and amperometry are not the same, though they are related electrochemical techniques. Excitation voltammetry involves applying a varying potential to a working electrode and measuring the resulting current to analyze redox reactions. In contrast, amperometry measures the current at a constant voltage to determine the concentration of analytes over time. Both techniques can provide insights into electrochemical processes, but they differ in their operational principles and data interpretation.
