摘要： A doubly clamped beam has an asymmetric piezoelectric layer within the beam with a gate proximate to the beam within a submicron distance with a gate and beam dipole. A suspended beam is formed using a Cl2/He plasma etch supplied at a flow rate ratio of 1:9 respectively into a plasma chamber. A parametric amplifier comprises a NEMS signal beam driven at resonance and a pair of pump beams driven at twice resonance to generate a modulated Lorentz force on the pump beams to perturb the spring constant of the signal beam. A bridge circuit provides two out-of-phase components of an excitation signal to a first and second NEMS beam in a first and second arm. A DC current is supplied to an AC driven NEMS device to tune the resonant frequency. An analyzer comprises a plurality of piezoresistive NEMS cantilevers with different resonant frequencies and a plurality of drive/sense elements, or an interacting plurality of beams to form an optical diffraction grating, or a plurality of strain-sensing NEMS cantilevers, each responsive to a different analyte, or a plurality of piezoresistive NEMS cantilevers with different IR absorbers.

摘要： The invention relates to the application of the techniques of nanoelectromechanical system (NEMS) to ultrasensitive mass detection. A pulsed flux of atoms is adsorbed onto the surface of a 32.8 MHz nanomechanical resonator (10) within an ultrahigh vacuum environment. The mass-induced frequency shifts from these adsorbates are then used to demonstrate a mass sensitivity of SIMILAR 1.46x10 Daltons (Da). For resonators (10) operating up to frequencies of 72 MHz, inverse mass responsivities as small as SIMILAR 8x10 grams/Hz (5x10 Da/Hz) are obtained. Our results offer a new approach to ultrahigh resolution mass spectrometry of individual, electrically-neutral macromolecules with clear prospects for single Dalton sensitivity.

摘要： Tunable, bio-functionalized, nanoelectromechanical systems (Bio-NEMS), micromechanical resonators (MRs), nanomechanical resonators (NRs), surface acoustic wave resonators, and bulk acoustic wave resonators having superhydrophobic surfaces for use in aqueous biochemical solutions. The MRs, NRs or Bio-NEMS include a system resonator that can vibrate or oscillate at a relatively high frequency and to which an analyte molecule (s) contained in the solution can attach or upon which small molecular- scale forces can act; a device for adjusting a relaxation time of the solution, to increase the quality (Q- factor) of the resonator inside the solution, to reduce energy dissipation into the solution; and a device for detecting a frequency shift in the resonator due to the analyte molecule (s) or applied molecular-scale forces. The resonator can include roughness elements that provide superhydrophobicity and, more particularly, gaps between adjacent asperities for repelling the aqueous solution from the surface of the device.
