“…Fennouh et al [165] compared the effectiveness of heavy metals salts at inhibiting lactate dehydrogenase activity. They showed that they could detect the presence of heavy metals below the European norms, with the exception of lead acetate.…”

Production processes require quality control. The quality of food going to the consumer must always be assured. Traditionally this was performed by taking a sample and sending it to a remote laboratory. While this is successful for most samples, this was not always the case. Having remote laboratories means that there could be a significant lag-time between sampling and results. Some unstable samples may have changed or the source material could have been already used/processed by the time they are analyzed. Sensor-based systems, especially those incorporated within flow injection analyzers, can overcome this problem. As the systems can be small and inexpensive relative to other automated analyzers, they can easily be fitted onsite. With the sensors fitted within the production process, a nearly instant reading can be achieved. The advantages and disadvantages of physical, chemical, and biosensors and their applicability to food analysis are discussed. Particular attention is focused on the improvements made to the underlying technology used in biosensor construction.

“…The mechanism of pesticides action, their high toxicity and their wide use in agriculture to protect crops from pests, represent a general hazard for environmental welfare and could become a real threat to life in the biosphere, so that their continuous monitoring in the environment is required. The need for such monitoring devices has intensified the work in the field of biosensors, in particular those based on the activity or inhibition of AChE [24,25].…”

“…Fennouh et al (1998) developed an amperometric biosensor with L-lactate dehydrogenase (LDH) and L -lactate oxidase. The biosensor had a lead detection limit of 0.2 µM and the enzyme membranes were stable for more than two months at 4ºC.…”
