GLUCOSE SENSOR UTILIZING SILICON PLANAR TECHNOLOGY NSF Summer Undergraduate Fellowship in Sensor Technology

A glucose sensor using silicon and platinum was designed and fabricated. The interaction of glucose oxidaise and glucose produces proteins which have dielectric properties that produce an electrical output measured through the bonding pads of a sensor. The sensor consists of two layers of platinum: one porous layer that serves as an area for the reaction to take place, and a second layer that consists of two bonding pads. The sensors were placed in solutions of different glucose concentrations. Their resistance was measured and it was found that in a solution of less concentration, the resistance was greater. We also researched non-invasive ways of measuring glucose. Technologies used included Raman spectroscopy, near-infrared spectroscopy, photo-acoustic spectroscopy and mid-infrared spectroscopy.
