Abstract: We present a nanobiosensor device based on evanescent wave detection by using optical waveguides in a highly sensitive interferometric configuration. The device is fabricated by standard CMOS microelectronics technology after a precise design of the device structure in order to achieve a high surface sensitivity for biosensing applications. Direct immunosensing with the sensor has been tested after a covalent bonding of the receptor layer to the surface device. A flow delivery system, optical bench for testing, data acquisition and processing of the signal have been also implemented.
