Biosensors, a powerful tool in herbicides residue detection

Detection of herbicides residues, includes a wide range of methods including biosensors, that are used for herbicide residue analysis. Biosensors are systems with small size, very accurate, sensitive, specific and portable that can measure analyte in very low concentrations in biological samples. Today, biosensors are used in various sciences, medicine, chemical industry, food industry, environmental monitoring, and pharmaceutical and health products. Biosensors consist of three components, bioreceptor, detector and processor. The importance of this method is very specific reaction to a particular analyte that thereby is prevented the intervention materials that is caused for inefficiency measured in many ways. These sensors are designed to react only with a specific substance. The result of this reaction is messages that microprocessor can analyze them. Since work on biosensors is based on biological systems embedded in them, so they do not have side effects on other tissues. In recent years with the design of nano-biosensors, the sensitivity of the measurement procedures has increased dramatically.
