Metrohm DropSens News

Dear Researcher,

Today, field-effect transistors (FETs) have become a sensing platform for a multitude of electrochemical and biological applications. These devices are promising bioelectronic transducers that enable low potential operation and stable potentiometric measurements.
 
In this newsletter, we present a new boxed connector to facilitate the use of gold field-effect transistor electrode with a coplanar gate. In addition, we accompany this release with an Application Note, where you can learn more about field-effect transistor characterization and performance studies.
 
Enjoy the read!

APPLICATION NOTE

BIDSC-FET

New boxed connector

 

Metrohm DropSens launches the BIDSC-FET, an accessory that acts as an interface between the AUFET interdigitated electrode and any (bi)potentiostat for easy connection. It is recommended when working with microvolume drops of sample.

AUFET30

Available gold field-effect transistor electrode

These electrodes are an attractive and validated alternative to conventional electrochemical sensing systems and consist of an interdigitated gold electrode (drain and source) with an integrated coplanar electrode (gate).
 
They could be easily modified with semiconductor materials, making them useful for a wide variety of applications in different fields. Their format is disposable and easy to use and also allows working with small sample volumes.

 

APPLICATION NOTE

New publication: characterization and performance studies of FETs using μStat-i 400

This Application Note provides detailed guidance on how to use the Metrohm DropSens (bi)potentiostat μStat-i 400 for the characterization and performance of FETs and their use as transducers.
 
In the following document, you will find some experiments demonstrating these applications using: a portable μStat-i 400 impedance analyzer, which includes mixed techniques (LSV+AD and CV+AD) suitable for these experiments (among others), and the AUFET30 electrode together with the dedicated BIDSC-FET connector.
