Gold field-effect transistor with coplanar gate



Interdigitated electrodes (IDE) are electrochemical platforms that include two interdigitated electrodes. The variation on the material of the electrode and the size and the separation of the digits makes them suitable for different applications enhancing sensitivity and detection limits


Number of WEs: 2 WE
Working electrode material: Gold
Substrate material: White plastic
Substrate size: Length: 3.40 cm x Width: 1.02 cm
Substrate thickness: 0.01 cm
Main features:

Single to use sensors that eliminate the electrode maintenance. The coplanar design of this integrated device facilitates its use and reduces the sample required for the experiment. They present high reproducibility and are ideal for working in decentralized assays or to develop (bio)sensors in environmental, clinical or agri-food areas.

Possible applications:

Devices for Field-Effect Transistor (FET) useful to obtain sensing phases

Additional information:

The interdigitated area (drain and source) should be modified with a semiconductor. The gate modification is optional for different purposes. The current circulated between the drain and
source is the parameter under study that varies depending of the WEs modifications.

Packaging: 50 units per pack
Storage: At room temperature, protected from light in a dry place.
Suitable connectors: BIDSC-FET
