Abstract:
A concentration sensor for at least one biological species in the blood includes a support, at least one waveguide, and an optomechanical resonator suspended from the support. The optomechanical resonator is optically coupled to the waveguide, and the optomechanical resonator is configured to vibrate in volume mode and includes at least one face extending in the plane of the sensor and configured to receive molecules of the given species. At least the face includes a functionalisation layer specific to the species, the optomechanical resonator having a smaller dimension in a direction normal to the plane of the sensor compared with the dimensions of the said face.
