image: Optical micrograph displaying the top view of an individual transistor. Scale bar, 20 μm. Inset shows a cross-section scanning electron microscopy image acquired at a tilt angle of 30°. Ion membrane (light red), channel (light blue) and Au contacts for gate (G) and source (S; beige) are visible. Scale bar, 5 μm. This material relates to a paper that appeared in the Feb. 27th, 2019, issue of Science Advances, published by AAAS. The paper, by G.D. Spyropoulos at Columbia University in New York, NY, and colleagues was titled, "Internal-ion gated organic electrochemical transistor: A building block for integrated bioelectronics." view more
