Abstract
In this work we report a self-assembled mixt into plat silicon (Si n-type, 10-20 Omegacm) coated with gold deposited by evaporation. The formation of mixed self-assembly monolayers (SAM) was characterized with FTIR-ATR, and cyclic voltammetry techniques. In order to assay the functionality of SAMs prepared for immobilization of high density of functional protein we used different concentrations of BSA in PBS. The protein (BSA) was labeled with Cy3 dye and printed onto coated slides using a microarray printer. The intensity of signal detected, for any one spot, is proportional to the quantity of antigen (BSA) bound on the surface. Those are preliminary experiments in order to test this surface for to immobilize one of the most pathogens Escherichia Coli O157:H7.
