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. Ion channels are biomolecules that allow charged atoms to flow in and out of cells, and they are an important work-horse in cell signaling, sensing, and energetics. They are also being explored for nanopore sequencing applications. As the “transistors” of living systems, they are the target of many drugs, and the ability to perform such fast measurements of these proteins will lead to new understanding of their functions.
