Paper Abstract

We propose a novel hemoglobin fiber-optic sensor which is based on the evanescent field of side-polished fiber. It is functionalized with a thin-layer of a hemoglobin-sensitive graphene oxide (GO) coating on a side polished optical fiber. The trace of hemoglobin concentration was measured by the variations in transmitted light intensity and the optical properties of graphene oxide. The sensor output was obtained successfully in response to hemoglobin concentration and sucrose concentrations. The side-polished fiber with GO film exhibited real- time and remote measurement of hemoglobin concentration with high precision.
