The patch-clamp technique involves a glass micropipette forming a tight gigaohm seal with the cell membrane. The micropipette contains a wire bathed in an electrolytic solution to conduct ions. To measure single ion channels, a “patch” of membrane is pulled away from the cell after forming a gigaohm seal.
What is the purpose of patch-clamp?
The patch-clamp technique allows the investigation of a small set or even single ion channels. It is thus of special interest in the research of excitable cells such as neurons, cardiomyocytes and muscle fibers. A single ion channel conducts around 10 million ions per second.

This approach was pioneered by Erwin Neher and Bert Sakmann in the 1970s and led to their being awarded the Nobel Prize in Physiology or Medicine in 1991.
