Advanced resonator mass sensor for molecule detection in droplet

Abstract

Purpose This paper aims to a novel fabricated resonator structure which consists of some single mechanical resonators as a mass sensor. Design/methodology/approach The structure is proposed to detect the target molecules and cells in a droplet. Also, at this design the mechanical coupling springs of the proposed structure are designed in such a way that it resonates in shear resonance mode which minimizes the damping effect. Findings This proposed design can be fabricated in different sizes due to the requirements of an application. Originality/value The proposed design is fabricated in mesoscale and its mass sensitivity is evaluated and reported in this paper.
