概要
- 論文の詳細を見る
A biological and chemical sensor with a rapid response in microlevel tests is required for health and environmental monitoring. Our approach to developing a high-performance sensor is to use a porous monolith-type ion exchanger having three-dimensional acceptors to sense bacteria. This porous monolith-type ion exchanger has an open-cellular structure with 5–50-μm-diameter pores. The concentration of bacteria in the solution can be detected by measuring the impedance of the monolith. We have succeeded in sensing bacteria Bacillus subtilis with a concentration as low as $8\times 10^{2}$ cells/ml. The porous ion exchanger is a potential high-performance device for biological and chemical sensing.
