Professor Matsuhiko Nishizawa, of Graduate School of Engineering, Tohoku University and Senior Researcher Kenji Hata of Nanotube Research Center, National Institute of Advanced Industrial Science and Technology (AIST) have jointly developed a device coined the "enzyme electrode seal" that has an uniform mixture of both enzymes and carbon nano-tubes (CNT) and has the world's best (25mA/cm2) electron transfer rate in aqueous solution of glucose. This device was used to develop a self-powered visual sugar monitor that can be applied to the surface of fruits to measure its sweetness. The research was conducted as a part of Japan Science and Technology Strategic Basic Research Programs (CREST) and a portion of the results has been published online in the German scientific journal Advanced Energy Materials on August 27, 2012. The paper's title is "Molecularly Ordered Bioelectrocatalytic Composite inside a Film of Aligned Carbon Nanotubes."
