Enzyme Sensors Based on Conductimetric Measurementtic action of some enzymes may be accompanied by a net change in solution electrical conductivity. As discussed by Lawrence (.), this conductivity change may result from a number of mechanisms. These Include:

Gobble

Microbial biosensors based on respiratory inhibitionicine, environmental monitoring, and food processing. A biosensor is a device that combines a biologic-sensing element with an electronic signal-transducing element. As biologic-sensing elements, enzymes, antibodies, receptors, organelles, and microorganisms, as well as animal and plant cells, can be used.

Disk199

Microbial biosensors based on potentiometric detection, such as pH, pNH., pNH., pCO., and so on. These devices generate the potential developed across an ion-selective membrane separating two solutions, proportional to the logarithm of the analyte concentration, according to the Nernst equation.

. This signal can result from a change in proton concentration, release or uptake of gases, such as ammonia or oxygen, light emission, absorption or reflectance, heat emission, and so forth, brought about by the reaction catalyzed by the enzyme. The transducer converts this signal into a measurable

Roy J. Eidelson,Mikhail Lyubansky circuits and ion-sensitive electrodes. Bergeveld (.) introduced the ISFET as a new device that combines the chemical-sensitive properties of glass-membrane electrodes with the impedance-converting characteristics of the metal-oxidesemiconductor field-effect-transistor (MOSFET).

The amperometric enzyme biosensors (.–.) are one member of the efficient category of chemical sensors in which the mode of signal transduction depends upon the electrochemical processes. The aim of this chapter is to outline the technique involved and the

The strategy was to attach redox complexes to the polymer backbone and use the resultant redox polymer to mediate electron transfer between the immobilized enzymes and the substrate electrode. The principles behind
