The invention relates to a diffractive device for chemical and biological analysis based on structured receptors on waveguides, which comprises: a waveguide and a recognition element consisting of a grating with receptors arranged on the waveguide and are intended to interact with target compounds present in a sample; and a radiation source that emits an incident beam propagated through the waveguide, interacting with the recognition element and being diffracted according to Bragg's law, thereby generating a reflected beam and a transmitted beam, which are collected by optical analyzers that record parameters of the reflected beam and of the transmitted beam, enabling multiple analyses to be conducted in a simple, fast, 15 sensitive and quantitative manner, label-free and in real time.
