Abstract

In order to realize real-time monitoring of calcium ion concentration, the invention provides a calcium ion detection photoelectrode based on special optical fiber surface film modification. According to the invention, the required calcium ion concentration sensor is produced by adopting a polymer-based optical fiber and calcium ion photoelectrode end surface modification method.

Description

technical field [0001] The invention belongs to the field of optical fiber devices, in particular to a calcium ion detection light electrode based on special optical fiber surface film modification. Background technique [0002] Calcium ions, as the main electrolyte of the human body, are of great significance to various physiological activities of the body. However, in the existing calcium ion detection methods, it is difficult to monitor calcium transients in vivo in real time during surgery. [0003] Optical fiber biosensors can meet the needs of rapid, accurate and in situ detection in many fields such as genomics, proteomics, medical diagnosis, environmental monitoring, food safety and so on. Compared with other biosensors, the optical fiber biosensor combines the characteristics of optical fiber sensing, which is specifically reflected in: due to the good insulation and shielding effect of the optical fiber itself, its anti-interference ability is strong, and it is no...
