Abstract

Optical glucose measurement is an attractive research topic for years. One of the goals is to develop a portable device for continuous and non-invasive monitoring of blood glucose for diabetics. In this work, a surface plasmon resonance (SPR) system, which has a high detection sensitivity of 7.61/spl times/10/sup -7/ refractive index unit (RIU), is utilized for measuring the glucose concentration in aqueous solution. The experimental results show that this approach, which measures the optical behavior of glucose solution, may possibly reveal a new pathway for the non-invasive measurement of blood glucose.
