Abstract
The invention relates to a device for mass detection of particles in a fluid medium, including an electromechanical oscillator (7), excitation means (9) fitted so as to cause the said oscillator to vibrate, a fluid supply circuit (5), and a fluid system (11) incorporated in the said oscillator, where the said fluid system (11) is in fluid communication with the fluid supply circuit (5), where the said fluid system (11) includes at least one trapping site (21) configured to trap a particle of interest according to the size of the said particle of interest.
Claims15
A device for mass detection of particles in a liquid medium, including an electromechanical oscillator, excitation means fitted so as to cause the said oscillator to vibrate, a fluid supply circuit, and a fluid system incorporated in said oscillator, where said fluid system is in fluid communication with the fluid supply circuit, wherein the fluid system includes at least one trapping site configured to trap a particle of interest according to the size of the said particle of interest.
A method for mass detection of particles in a liquid medium, implemented with a detection device including a fluid system and an oscillator, said method comprising the following steps:
- supplying the fluid system with a solution of interest, causing the oscillator to vibrate at a resonant frequency, and
- detecting a shift of the resonant frequency relative to a reference resonant frequency.
