Abstract :
A very sensitive optical method of total internal reflection ellipsometry (TIRE) in conjunction with an immune assay approach were exploited for the registration of low molecular weight environmental toxins, such as simazine, atrazine and T2 mycotoxin in a wide range of concentrations down to 0.1 ng/ml. QCM impedance measurements provided additional information on the mechanism of T2 binding.
