News From the Field
Researchers Perform Fastest Measurements Ever Made of Ion Channel Proteins

May 20, 2013

The researchers designed a custom integrated circuit to perform these measurements, in which an artificial cell membrane and ion channel are attached directly to the surface of the amplifier chip.
