Author: Kai Li. There are several works about the detection of glyphosate using the immunoassays, the vast majority is based on the enzyme-linked immunosorbent assay (ELISA) [81,82,83,84,85,86]. Gonzalez et al. [ 87 ] reported an optical immunosensor that has advantages over conventional immunoassays—such as rapid response, full automation, and sensitivity Cited by: 7.
To characterize and quantify agrochemical exposure and effects to cells, organisms, and ecosystems, appropriate biomarkers need to be elucidated and characterized. The newest measurement technologies need to be examined and optimized with respect to environmental and biological matrices.
Effective and economical technologies are also needed to clean up soil.

Immunosensors are solid-state devices in which the immunochemical reaction is coupled to a transducer. They form one of the most important classes of affinity biosensors based on the specific recognition of antigens by antibodies to form a stable complex, in a similar way to immunoassay.
Depending on the type of transducer there are four types of immunosensor:. This paper presents a revision on the instrumental analytical techniques and methods used in food analysis together with their main applications in food science research.
