“…The various types of optical transducers exploit properties such as simple light absorption, fluorescence/phosphorescence, bio/chemiluminescence, reflectance, Raman scattering, and refractive index. SPR as a further transduction mechanism shows a main advantage over most optical biosensors, because of the direct determination of the analyte without the use of labelled molecules [36]. SPR is an optical biosensor technique that measures molecular binding events at a metal surface by detecting changes in the local refractive index (Figure 1).…”

“…The biosensor based on cellobiose dehydrogenase (CDH) is used both in industry and environmental protection [54]. Biosensors containing nitrate reductases (NR), phosphatases, and ureases [15] were used in environmental research, like tyrosinases for detecting phenols and catechols in food and pharmaceuticals, as well as in clinical and environmental samples [16]. Examples of potential applications of enzymes are presented in Table 2.…”

The last two decades has seen a significant increase in interest in biosensors. According to the Web of Science database, the number of scientific publications over the past 20 years increased from 309 in 1993 up to 3,467 in 2013 (Fig. 1).The demand for developing new detection methods, increasing interest in visualization techniques [1][2][3], emphasis placed on new drug discovery programs [4], diagnostic test development [5][6][7], and attempts to explain cellular action mechanisms and to trace a cell's metabolism pathway [7,8], and the possibility of using biosensors in numerous fields of application, (for example: medicine [9-11], environmental protection [12-14, 16-17], food industry [18], and defense industry [19]) has results in an increasing number of research projects targeted at biosensor design and fabrication. Biosensors used in environmental monitoring measure the toxicity effect based on the detection of a chemical compound or compound group by selective recognition of a biomolecule in the receptor layer and then by detection of a signal after passing through the transducer layer [16].The application of fluorescence biosensors in environmental protection applications [20][21][22][23][24][25], medical diagnostics [26][27][28][29][30][31][32][33][34][35], and industries [36][37][38][39][40][41][42][43][44][45] also is growing.Pol. J. Environ. Stud. Vol. 24, No. 1 (2015) AbstractEnzyme-based fluorescence biosensors and their applications in environmental protection, medicine, and industry are described. Biosensors used in environmental protection measure toxicity effects. A chemical compound or group of compounds is detected by the recognition of molecules in the receptor layer and then by detecting a signal passing through the transducer layer. Biosensors are classified according to the transduction method. Special emphasis is placed on optical biosensors, especially fluorescent biosensors, and such measurement techniques as FRET (Fröster resonance energy transfer), FLIM (fluorescence lifetime imaging), FCS (fluorescence correlation spectroscopy), and changes in fluorescence intensity. The phenomenon of fluorescence in biosensors and the selection of appropriate methods are described. The use of enzymes in the receptor layer and enzyme classification according to its category and functions used for analyte detection are presented. The fluorescence properties of enzymes resulting from possessing such cofactors as flavin or heme (prosthetic) groups are discussed. Several methods for enzyme immobilization, namely entrapment, adsorption, covalent immobilization, cross linking, and affinity interaction are described, and the use of enzymatic fluorescence biosensors in the detection of analytes is presented.
