Chapter
Immunosensors
The development of practical immunosensors is an important topic for biosensor research. Recently the authors have demonstrated novel immunosensors, such as the immuno-FET sensor, the piezoimmunosensor, the pu...

Chapter
Micro-Biosensor
ISFET is utilized as a pH sensitive transducer, so that the enzyme or micro-organisms, which catalyze the reaction that involves pH changes, were coupled with the ISFET to construct a micro-biosensor. A micro-...

Chapter
Microbial Sensors and Microbiosensors
A novel BOD sensor with a new principle employing a luminous bacterium, Photobacterium phosphoreum, was developed. The increased intensity of luminescence resulting from the cellular assimilation of organic compo...
