The use of bioelectronics is a quickly evolving and developing field offering novel application to solve problems across numerous biological disciplines. Cancer research has focussed on various biomarkers as a means for detection and for potential therapeutic treatments. Several therapies and medications focus on influencing redox state within the cellular environment, with some of these therapies utilising cyclic redox components, allowing for repeated oxidation/reduction at target sites. This offers great potential for electrical (DC and AC) and electrochemical control over the intracellular redox environment. Herein explores the redox circuits in cancer and its metabolism, the influence of mediated oxidative stress in redox altered environments, therapeutics that target specific redox pathways and their redox active proteins, and the implementation of electrochemical interrogation to control the cellular redox environment to manipulate cancer metabolism.
