Method for detecting targets using a mechanical oscillator and functionalized particles

Abstract

The invention relates to a method for detecting at least one target, implemented using a detection system which comprises a measuring device (1_A, 1_B) comprising a mechanical oscillator (11_A, 11_B) and a fluid circuit (10_A, 10B) integrated into the oscillator and in which a fluid containing said at least one target to be detected is caused to circulate, said oscillator (11_A, 11_B) being capable of being excited according to several vibration modes (M_1, M_2, M_3) and comprising on the fluid network at least one first trap positioned on an anti-node of a first vibration mode of the oscillator and a second trap positioned on an anti-node of a second vibration mode of the oscillator, a vibration anti-node corresponding to a position in which the vibration amplitude ranges from 80% to 100% of the maximum amplitude for the selected vibration mode.
