    Abstract:
    Langmuir-Blodgett (LB) technique appears to be quite suitable for generating biospecific surfaces and it has potential application for fabricating biosensors. In this work, mixed Langmuir-Blodgett films of immunoglobulin G/amphiphile have been transferred onto hydrophobic silver surface previously modified by 1-octadecanethiol (ODT) SAMs. In order to obtain stable LB films, the influences of different parameters - type of amphiphile, surface pressure and pH - on the properties of mixed IgG/amphiphile monolayer, were investigated. Electrochemical properties of the engineered immunosensor have been measured by impedimetric spectroscopy. The immunosensor obtained exhibits a high sensitivity and a good specificity in a linear dynamic range from 200 to 1000 ng ml(-1).
