[Advance of pesticide residue analysis techniques based on biological principle].
The application of pesticide residue analysis techniques based on biological principle, such as immunoassay, biosensor and direct test the influence of pesticide upon the activity of the enzyme and the growth of the propagation, was reviewed in this paper. Immunoassay is a kind of precise and sensitive method, but it's not easy to produce the antibody of pesticide. The strongpoint of biosensor is the process of the detection is quickly and real time, but the sensitivity and stability of biosensor still need improve. The tests based on the activity of the enzyme and the growth of the propagation are simple and inexpensive, and are useful in the situation of acute-poisoning and severe contamination. These techniques general work fast, cost inexpensive, and do not need large-volume unit, so they have a good large potential in extensive pesticide residue monitoring and spot assays.
