ABSTRACT
It was proposed simple SOS-type biosensor based on the fiber optics worked in differential regime and allowed the control of such environmental objects which are chemical nature. This biosensor was tested at the determination of the genotoxicity of the number substances as: ethanol, dimethylsulfate and mitomycin C. The sensitivity of the proposed biosensor corresponds to the approaches based on the application based on the traditional, complicate and expensive devices. The developed biosensor may be used for the express analysis, namely during 20 min if the optrodes with the appropriate immobilised cells will be prepared in advance. It was informed that according to the preliminary obtained results the functional activity of such prepared optrodes may be served up to one day. Moreover, it was concluded that the proposed biosensor may have perspective in future for the using in field conditions.
