SENSOR FOR DETECTING A TARGET ANALYTE IN A LIQUID MEDIUM WITH AN OPTICAL RESONATOR COUPLED TO A MECHANICAL RESONATOR

摘要

Sensor of the concentration of at least one biological species in the blood comprising a support (2), at least one waveguide (4), an optomechanical resonator (6) suspended from the support (2), said optomechanical resonator (6) being optically coupled to the waveguide (4), said optomechanical resonator being configured to vibrate in bulk mode and comprising at least one face extending in the plane of the sensor and configured to receive molecules of said given species, at least said face comprising a functionalization layer specific to said species, said optomechanical resonator having a small dimension in a direction normal to the plane of the sensor with respect to the dimensions of said face.
