Abstract

A newly designed dual fiber optical sensor is reported. It can sense both oxygen and carbon dioxide in gas phase with one sensing layer made of immobilizing fluorescent dyes Pyrene Butyric Acid (PBA) and Hydroxy Pyrene Trisulphonate (HPTS) in the same matrix. Its resolution is 0.1% for carbon dioxide and 0.5% for oxygen in clinical detecting range.

摘要

据报道，一种新设计的双光纤光学传感器问世。它可以在气相中同时检测氧气和二氧化碳，其传感层由固定在同一基质中的荧光染料芘丁酸（PBA）和羟基芘三磺酸盐（HPTS）制成。在临床检测范围内，其对二氧化碳的分辨率为0.1%，对氧气的分辨率为0.5%。
