Abstract
A sensor for sensing the concentration of at least one biological species in blood includes a support, at least one waveguide, and an optomechanical resonator hanging to the support. The optomechanical resonator is optically coupled to the waveguide. The optomechanical resonator is configured to vibrate in a volume mode and includes at least one face extending in the plane of the sensor and is configured to receive molecules of the given species. The optical resonator includes a body comprising an optical active area and an optical insulation layer deposited at least in line with the optical active area so as to confine at least partially an electromagnetic wave in the body.
