Cyclic voltammetry

Definition

Cyclic voltammetry is an electrochemical technique used to study the redox (reduction-oxidation) properties of materials by measuring current as a function of an applied voltage over time. This method involves sweeping the potential of a working electrode linearly and then reversing it, which allows for the identification of the electrochemical behavior of biomimetic materials in their in situ environment, providing insights into their stability and reactivity.
