摘要：

A piezoelectric crystal immunobiosensor has been developed for the assay of atrazine herbicides in drinking water. Determinations from 0-03-100-mu-g l-1 (parts per billion) of atrazine can be made with a relative SD of about +/-8%. Atrazine antibodies (polyclonal from sheep) are layered onto the gold electrode of 10 MHz piezoelectric crystals, which are precoated with protein A. The sensor is reversible, being reusable for about eight or nine assays.
