Abstract (Summary)

The goal of the proposed research is to investigate a new noninvasive method for glucose monitoring in diabetic patients. Currently, diabetic patients must perform finger pricks multiple times a day to measure their blood glucose level. This method is painful, time consuming, and costly. Recent studies have shown that the analysis of volatile organic compounds (VOCs) in exhaled breath can be used as a novel noninvasive method to monitor blood glucose levels. Thus, this project is aimed to develop a miniaturized gas biosensor to measure elevated acetone levels in a patient's exhaled breath. As part of this investigation, metal oxide films were prepared and deposited on alumina substrates and the sensor response was characterized by measuring the resistance of the sensing element with and without the presence of the target volatile organic compound.
