A fiber-optic sensor has been prepared which responds to carbon dioxide at physiologically significant concentrations. It is based on pH modulation by dissolved carbon dioxide in a sensing layer of fluorescent dye. By use of a previously developed methodology by which the sensing chemistry is bonded directly to the glass fiber tip, the miniature size of the sensor is preserved. This method involves consecutive applications of solution polymers to the fiber tip rather than mechanical attachment of sensor reagents. Preparations of polymer-immobilized dyes and polymer membranes are described.
一种光纤传感器已制备完成，它能对生理上具有重要意义的二氧化碳浓度做出响应。该传感器基于溶解在荧光染料传感层中的二氧化碳对pH值的调节作用。通过使用一种先前开发的方法，即将传感化学物质直接键合到玻璃纤维尖端，传感器得以保持其微型尺寸。这种方法涉及将溶液聚合物连续应用于纤维尖端，而不是机械附着传感试剂。文中描述了聚合物固定化染料和聚合物膜的制备方法。
