Rezumat:

Biosensors are one of the recent scientific domains with large applicability in environmental
biomonitoring, medicine, and food analysis. Electrochemical biosensors are measuring systems
based on the combination of both biochemical and electronic elements in one unit. This short report
presents contributions from Romania, Europe and South America to detect organophosphorus (OP)
pesticides in water employing sensitive and specific enzymatic sensors based in mutant
acetylcholinesterase enzymes. The studies were carried out by three universities (Universidade Federal
do Maranhão, Brazil, Transilvania University of Brasov, Romania, and University of Perpignan,
France), involving researchers and students with different backgrounds: analytical chemistry,
biochemistry, microbiology, and electronics. The aim of the experimental study was to develop and
to characterise highly sensitive enzymatic biosensors for OP detection in aqueous medium.
