A method for the detection of analytes within a fluid, said method comprising the steps of prearranging a sensorized device () comprising at least one SAW sensor (), said or each SAW sensor () comprising a substrate () having an outer surface ('), at least one emitting interdigital transducer () and at least one reflector electrode (). There are then the steps of adsorbing a plurality of probe molecules, sending n input electric signals, having respective frequencies f, and subsequent transmission of at least one surface acoustic wave, reflecting by said or each reflector electrode () of said or each surface acoustic wave emitted, identifying at least one resonance frequency f, conveying said fluid on said outer surface (′), removal of said fluid by said outer surface (′), verifying a possible change of value of at least one resonance frequency fpreviously identified.

Sensorized device for the analysis of a fluid by means of acoustic waves

A device for controlling fluid motion in a micro/nanofluidic structure of channels by means of surface acoustic waves is described. The device comprises a structured volume of material bearing a predetermined configuration of micro/nanofluidic channels for holding and transferring amounts of fluids adapted to define at least one fluid inlet and at least one fluid outlet and presenting a hydrophobic behaviour for the fluids to be handled and a substrate made of material with piezoelectric properties coupled to the micro/nanofluidic channels.
