Morphological identification through electron microscopy (SEM) and Ellipsometric studies of E.coli O157:H7 cells adsorbed onto surface

The purpose of the present work is to test of a new biosurface for qualitative detection of E. coli O157:H7 by SEM and Ellipsometry methods. The bacteria are attached onto surface with a method based on reactions between antibodies and antigens, very specific to bacterial serotypes that cause food safety concerns: E.coli O157:H7.
