This paper demonstrates the use of Guided Mode Resonance (GMR) optical sensor platform for detection of Glycated Hemoglobin (HbA1c) in human blood. HbA1c is an importance biomarker for monitoring a long-Term glucose level in diabetes patients. Here, the sensing approach utilizes boronate affinity by modification of the GMR surface with 3- Aminophenylboronic acid (PBA). The sensing signal is then measured via a resonance shift in a reflection spectrum as the change of the refractive index on the sensor surface. In preliminary experiment, standard HbA1c samples with concentration covering the detection range (5% and 10 %) are used. The results show a good trend of resonance shift corresponding to amount of HbA1c.Mahidol UniversityComputer ScienceConference PaperSCOPUS10.1109/CLEOPR.2017.8118890
