Biosensors and environment

The portable measurement and field, that is, without the need to send a sample to the laboratory, which allows the new technology is very useful for measuring pollutants in the atmosphere very much.

The clearest example is already being implemented is the measurement of biochemical oxygen demand (a parameter used to record the number of bacteria that are in the water). The test is more important than it takes to be a liquid contaminated. With conventional technology that test application about five days, with the new, the results are obtained in 20 minutes. In addition, an alarm system, biosensors can be alerted immediately if a plant is exceeding the limit emission of pollutants.

“There is a lot of pollution because they do not know that we are measuring. If there is no adequate technology to measure this there is no how to recognize, “said Professor Turner.

The food control
At the international level the focus is on detecting contaminated food or modified, and that can affect health. Biosensors are used to control the processes computerized processing of foods. To alert the system about an abnormality, it can be reversed auto mantic mate. In Germany there are already on supermarket shelves with products that include chips warn that if you cut the cold chain.

“It is now being manufactured biosensors to recognize micro toxin as or Salmonella, for example. Are planning to create sensors to apply in cases of mad cow? Particularly interested in the UK in working with products derived from transgenic plants to identify them, and also to genetically modified plants. This will come to evaluate its effects on health, “the specialist.
