Non-Invasive Diabetic Sensor Based on Cellulose Acetate/Graphene Nanocomposite

摘要

Metabolic changes or pathological disorders are a promising tool for non-invasive medical diagnosis,occurring in human exhaled breath as a measurement of volatile organic compounds,such as the exhaled acetone quantities in expressions of monitoring of diabetes.Basis of acetone recognition and non-invasiveness are the most apparent physiognomies of the arrangement.The patient's breath samples are collected beforehand and then passed through the container before the reaction with the sensors and the final result data are put out on the screen at regular intermissions.A conductive composite based on cellulose acetate and thermally reduced graphene are prepared to fabricate the highly selective acetone sensor(especially for the diabetics.In the panorama of future developments of devices investigating real breath samples,a complex occurrence is studied with down to 1 ppm of acetone,ethanol,and methanol(mixed with water)with a sufficiently good signal to noise ratio and is worth inspecting.
