Nowadays, a number of people afflicted with diabetes mellitus is increasing from 382 million to 592 million as a forecast for a period from 2013 to 2035. In 2011, 1.4 million people around the world had died due to diabetes mellitus being the one of the 8 top causes of death. Diabetes is a disease causing serious long-term influence. The most significant consequences are cardiovascular, retinal, renal and neuropathic pathologies. Determination glucose concentration in blood is an important method to diagnose the patients who are afflicted by diabetes mellitus. Conventional blood examination methods using drawn blood such as test-strip, electronic glucose meter, interstitial blood fluid and enzyme electrodes are invasive techniques leading to the risk of infection. They are also painful and uncomfortable in several situations. Noninvasive techniques were developed for glucose monitoring as well as other blood analysis. They eliminated the disadvantages of invasive methods. Many optical techniques were employed to overcome the drawback such as polarized light measurement, Raman spectroscopy, near infrared spectroscopy and others. They provide non-ionized and reduce the risk of radiation for medical applications.
