A low-volume microstructured optical fiber hydrogen peroxide sensor

Abstract

Optical fibers are ideal for environmental sensing applications because of their ability to transmit optical signals to and from the sensing region without the use of free-space optics. Through the use of suspended core MOFs we can exploit the interaction between the evanescent field of the fiber and a target molecule to facilitate detection. The aim of this work is to increase the sensitivity of the system, and to examine the primary factors such as the background glass fluorescence currently restricting the detection limit. This work is focused on biological detection in liquid samples using Quantum dots.
