Verrucarin A2 (VerA) is a toxic trichothecene mycotoxin that can be produced indoors at very low level by moulds contaminating dwellings and may be associated with several human health problems. In this study we describe a spectroscopic label-free biosensor for VerA. This sensor is based on the high sensitivity of Fourier transform infrared-attenuated reflection (FTIR-ATR) spectroscopic detection and the use of a new anti-VerA rat monoclonal antibody (mAb). This antibody was directly grafted at the surface of the infrared element. Competitive ELISA and FTIR-ATR techniques were compared…
