Dynamical Response of Nanomechanical Resonators to Biomolecular Interactions

We made a simple model for understanding the dynamic behavior of nanomechanical resonator in response to biomolecular interactions. Specifically, in our model, we considered the nanomechanical resonator, on whose surface the biomolecules (dsDNA) are adsorbed, such that Hamiltonian of the system consists of elastic bending energy of nanomechanical resonator and potential energy for biomolecular interaction (i.e. DNA-DNA interaction). It was shown that DNA-DNA interaction plays a role on the resonant frequency shift for nano-scale resonators. This work was accepted for publications at Physical Review B.

Microcantilever operated in liquid environment for in-vitro biomolecular detection

We have recently reported the piezoelectric thick film microcantilever, which enables the in-situ real-time detection of the protein related to disease (e.g. C reactive protein) in liquid environment. This work was published at APL (click here).
