Abstract:

The results of the indication of the A (H3N2) influenza virus, strain A/HongKong/4801/2014 using a biosensor based on a silicon nanowire field-effect transistor are presented. In the experiment, specific and non-specific antibodies to this virus contained in blood serum were used. It is found that the influenza virus is electrically neutral at the “nanowire surface–suspension” phase interface; “antigen–antibody” mixtures BPL–H1 and B–BPL have an electrically negative charge at this interface.

Keywords:
