They are therefore of broad interest in biotechnological applications such as biosensors and bio-fuel cells. Here we will introduce the basics of enzyme connection at an electrode. We will show that electrochemistry can be used to fundamentally understand the enzyme behavior, and to evaluate the performances of the resulting bioelectrochemical devices.
