An Application of CLPFG for Detecting Diabetes Mellitus

Abstract

The prevalence of Diabetes Mellitus (DM) has increased in recent decades. So far, there have developed quite some methods for detecting DM, such as fasting plasma glucose (FPG) test, oral glucose tolerance test (OGTT) and random plasma glucose test. However, there is no standard technique that is followed universally for detection of glucose in urine. In this study, application potential of corrugated long period fiber grating (CLPFG) sensor technology to detect glucosuria (glucosuria is the excretion of glucose into the urine) has been investigated. The CLPFG was coated with Copper (II) hydroxide - Cu (OH)2. After that, the coated CLPFG was utilized for detecting glucosuria. It was possible to increase the refractive index sensitivity of CLPFG for detecting the presence of glucose in urine and in other solutions as well. The implication of this result lies in an understanding of the new methodology employed to detect specific materials in solutions.
