Selective sample preparation techniques are particularly attractive for the analysis of trace amounts of small molecules in complex matrices. In this article, Ron Majors covers the field of immunoextraction, a technique that employs immobilized antibodies to selectively capture specific analytes using molecular recognition via antibody–antigen interactions. Recently, the introduction of commercial products for specific high-volume environmental and food safety applications should spur further applications of this technique.
