A team of researchers at Columbia Engineering has used miniaturized electronics to measure the activity of individual ion-channel proteins with temporal resolution as fine as one microsecond, producing the fastest recordings of single ion channels ever performed. They 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.
