Electrochemical Sensors in the Analysis and Control of Bioprocesses

Abstract

The need for real-time, in-situ monitoring and control of the chemical composition of fermentation reactions has led to several novel approaches in the development of amperometric electrochemical sensors.

A New Approach for the Spectroscopic Detection of Different pH-Values

“…Such small scale devices pose great challenges for measurement technology. In case of bioreactors the continuous monitoring of pH, pO 2 and pCO 2 are most essential [1,2].…”

Preparation of glucose oxidase membrane for the application of glucose sensor by plasma activation

“…Furthermore, various kinds of biosensors can be prepared, by modifying the electrode surfaces with the immobilized enzyme, and the characteristic reaction properties, sensitivity, and application range of the electrodes can be improved. 2 Basically, there are three kinds of immobilization methods, i.e., the entrapped method, the adsorption method, and the chemical method. The applications of these traditional immobilization methods are restricted by the limited selection of insoluble support materials and reagents and by their complex preparation pro~edures.~~ Recently, the application of low temperature plasma to treat the polymer material has gotten more and more attention.…”
