Abstract
The ion image sensor was invented. The device enables two dimensional visualization of both the ion and optical imaging of chemical activity of solutions and cell activity. The CMOS device consists of an array of CCDs covered with functionalized membrane. Changes in the concentration and two dimensional distributions of several ions are detected by charge accumulation. We have recently reported on the use of the sensor for real time imaging of acetylcholine (ACh) enzyme reactions. Insights in the variation of the concentration of ACh may lead to new methods for the treatment of Alzheimer's disease.
