Blood testing chip. Macro photograph of a microchip used for instant testing of small blood samples. The chip is based on an Isfet,an ion- sensitive field effect transistor. This is a special transistor mounted on a substrate which attracts specific ions. As the ions accumulate,there is a change in electrical potential across the transistor. This can be measured by a microcircuit,thus forming a highly-sensitive chemical detector. Several Isfets,each sensitive to a different ion,can be joined together to make a miniature analysis device. Linked to a computer,the device could produce results for a doctor in about 30 seconds | |
