Abstract: Device for detecting biomolecules, comprising a container (2) intended to be filled with a mixture comprising a biomolecule (30) to be detected, a reagent (4) bondable to the biomolecule (30) and susceptible of emitting a first light radiation (λ 1 ) in fluorescence or chemiluminescence, and a plurality of magnetic beads (41) chemically bondable to the biomolecule (30). The device comprises a first detector (71) for detecting the first light radiation (λ 1 ) for detecting the biomolecule (30) concentration (C), a first emitter (61) for emitting a second light radiation (λ 2 ) for irradiating the magnetic beads (41), and a second detector (72) for detecting a third light radiation (λ 3 ) consequently transmitted, reflected or emitted by the magnetic beads (41) for detecting the quantity of magnetic beads (41). The device also comprises a logic control unit (8) configured for calculating a correct concentration (C) value of biomolecule (30) on the basis of the above measurements of the light radiations (λ 1 , λ 3 ).
