Bipolar Electrochemistry for Opening New Pathways in Micro- and Nanotechnology

Bipolar electrochemistry is a somewhat unconventional way of performing electrochemical experiments, as it allows carrying out redox reactions on conducting objects present in solution in a wireless way, due to their polarization in strong electric fields. The concept has been known for decades¹, but undergoes currently a true renaissance in various scientific domains, with applications ranging from analytical chemistry to materials science^2-4.

In this lecture Iwill illustrate that the approach is a very powerful tool, especially for micro- and nanotechnology, because many objects can be electrochemically addressed simultaneously and without a physical connection to a power supply. I will describe some applications, either concerning the highly controlled surface modification of micro- and nanoobjects^5-11, or with respect to the design of dynamic systems^12,13, which are able to show different properties, including for example light emission^14,15, enzymatic recognition¹⁶ and electronic functionalities¹⁷.
