Interdigitated Electrodes/ Microelectrodes
INTERDIGITATED ELECTRODES (IDEs)/ Microelectrodes
Interdigitated Electrodes
DropSens interdigitated electrodes (IDEs) are composed of two interdigitated electrodes with two connection tracks, on a glass substrate.

These IDEs offer several advantages, such as working with low volumes of sample and avoiding tedious polishing of solid electrodes.

The interdigitated configuration typically enhances sensitivity and detection limits.

They are suitable for decentralized assays, to develop specific (bio)sensors and other electrochemical studies.

The cell constant "Kcell" is a basic parameter of this electrodes, download here information about the experimental value for each reference.
