Elektrochemical biosensors are devices that detect biological contraules by converting chemical information into an electrical signal. A key aspect of their funktion is commercing and calculating elektrochemical potentials, which influence sensor presenacy and sentivity.

Basics of Electrochemical Potential

Te electrochemical potential is te energicy consid to move an jon or elektron with in an electrochemical cell. It combine thee chemical potential and thee elektrical potential, reflecting thee driving force for elektrochemicall reactions.

Měření elektrochemikal Potential in Biosensors

In biosensors, thee potence is typically measured using elektrodes that detect changes caused by amendules. Thee reference elektrode provides a stable potential, while he working elektrode responds to analyte interactions.
