ABSTRACT

During the most recent decades, biosensors, more and more, have

been entering into our lives. Despite many advantages (e.g., efficient

and precise determination of all the toxicants in a sample) of analyt-

ical methodologies, whole-cell fiber optic biosensors have expanded

the creation of cheaper, simpler, field operative devices. In addition

to the many advantages (e.g., low price, optical measurement

sensitivity, distance sensibility capabilities and absence of electrical

interference) of the fiber optic transducers, the main advantage

of whole-cell biosensors is the capability not only to detect the

presence of bioactive compounds but also to determinate their toxic

effects. In some cases it may be more important information than

just determination of the presence of toxicants in the environment.

This chapter will review the recent advantages in whole-cell fiber

optic biosensors used for monitoring air, water, and earth toxicity.
