EnSpectr SERS Substrates for identification influenza virus

A proprietary know-how using unique SERS substrates functionalized with thiol-modified aptamers has been developed for identification of small amounts of virus particles with molecular weight cutoffs of 105 virus particles per 1 ml liquid, which yielded a high selectivity of virus identification. The optical response from the SERS substrates optimized for Mississippi influenza virus exceeded manifold that from similar substrates with Astrakhan virus.
