A new immune technique based on the nanostructured silicon and intended for the quantitative determination of some toxic substances is offered. The main principle of the proposed immune biosensor work is consisted in the measurement of the changes of the photocurrent of the photosensitive nanostructured silicon at the interaction of its surface preliminary treated by the specific antibodies with the toxin solution. The sensitivity of such biosensor allows determining T-2 mycotoxin at the concentration of 10 ng/ml during several minutes. Overall time of the analysis of one sample including of all procedures is about 40 min. These indexes fit with the practice demands. [DOI: 10.1380/ejssnt.2009.677]
