  • Device for detecting an analyte via photoacoustic detection
    Patent number: 11674931
    Abstract: Photoacoustic detecting device (1), intended to be applied, via a contact face (3), against a medium to be analysed, the device comprising: a hollow cavity (20) comprising a first aperture (22) produced in the contact face, the cavity being bounded by a containment shell (21) that extends around the first aperture; a pulsed or amplitude-modulated light source (10) configured to emit, in an emission spectral band (??), an incident light wave (11) through the cavity (20) to the first aperture; an acoustic transducer (28) linked to the cavity and configured to detect a photoacoustic wave (12) extending through the cavity. The photoacoustic detecting device is optimized to increase the amplitude of the photoacoustic wave detected by the acoustic transducer.
    Type: Grant
