The biofunctionalization of nanoelectromechanical structures is critical for
the development of new classes of biosensors displaying improved performances
and higher-level of integration. We propose a modified microcontact printing
method for the functionalization and passivation of large arrays of
nanocantilevers in a single, self-aligned step. Using fluorescence microscopy
and resonant frequency measurements, we demonstrate (1) the bioactivity and the
anti-fouling property of deposited antibodies and BSA molecules and (2) the
preservation of the nanostructures' mechanical integrity.
