Zearalenone( ZEN) is a common fungal toxin in agricultural products. The existing detection methods of ZEN are complicated,with precious instrument,and the samples usually need to be marked.Based on the self-developed surface plasmon resonance( SPR) biosensor,the biochip for ZEN detection was prepared and the direct detection method and inhibition detection method were proposed. The preparation process of the biochip was as follow: modifying the gold film by self-assembled monolayer( SAM) technique; activat...
