Abstract
Vibrio fischeri (marine bioluminescence bacteria) is known for changes in the quantity of bioluminescence by a chemical substance. Recently, attempts have been made to develop a biosensor using this characteristic. One problem is that it is difficult to use as a biosensor in culture solutions. In this study, a biosensor was made by the bacteria immobilization method using agar and magnetic force (ferromagnetic powder). The relationship between the concentration of a chemical compound and the quantity of immobilized bacterial bioluminescence was examined to evaluate the convenience of a new magnetic biosensor.
