In electrochemistry it is very common to work with so-called 3 electrode cells. These cells have: The RE is perhaps the one that is most difficult to understand for those starting in electrochemical research. In this post we explain in…
What is a biosensor? A biosensor is a device that uses biological receptors to selectively detect molecules, biomolecules, pathogens or ions. These receptors tend to be enzymes, antibodies, DNA, RNA or even whole cells. How does a biosensor work? Biosensors…
What is a chemosensor? Chemosensors are devices that detect molecules, biomolecules or ions How does a chemosensor work? Chemosensors work via molecular interactions happening between a receptor bound to a surface and an analyte. In electrochemical chemosensors, the receptors are…
What are microfabricated electrodes? Microfabricated electrodes are devices characterized by having: a very thin electrode, normally in the 100 to 2000 nm range a high purity electrode composition small features than SPEs, normally from 1 micrometer How are microfabricated electrodes…
Screen printed electrodes are one of the most common consumable in modern electrochemistry labs. Being the disposable and miniaturized version of electrochemical cells, screen printed electrodes enable scientists to perform multiple experiments without utilizing too much space. Thus helping enhance…
