Abstract
A novel molecularly imprinted polymer (MIP) coated bulk acoustic wave (BAW) sensor was fabricated for liquid phases. It can be used as a sensitive portable implement for the assay of 2,4-dichlorophenoxyacetic acid. A logarithmic response relationship between 2.0 x 10(-7) M and 5.0 x 10(-4)M was found. The detection limit was 1.0 x 10(-7) M. Recoveries were 93.2-108.7%. Influencing factors were investigated in detail and optimized.
