ABSTRACT
The use of enzymes in analytical laboratories facilitated the chemical analysis of important bioorganic species and led to new methodological trends. In enzymes we have available specific reagents that first proved efficient in spectrophotometric methods that prevailed in clinical chemistry in the past. These methods, however, often require special reagents and long reaction times, due to complicated procedures. Besides, even well-equipped and organized analytical centers do not supply the results in time in urgent situations. For quick feedback intervention, the need for a direct measuring device is being felt, which would make it possible to carry out nondestructive analysis with the possibility of data transmission.
