ABSTRACT:
The present invention provides methods, devices and device components for detecting, sensing and analyzing molecules. Detectors of the present invention provide good detection sensitivity over a wide range of molecular masses ranging from a few Daltons up to 10s of megadaltons, which does not decrease as function of molecular mass. Sensors and analyzers of the present invention detect emission from an array of resonators to determine the molecular masses and/or electric charges of molecules which impact or contact an external surface of a membrane that is used to mount and excite the resonators in the array. Resonators in the array are excited via piezoelectric and/or magnetic excitation of the mounting membrane and, optionally, grid electrodes are used in certain configurations for electrically biasing for the resonator array, and for amplification or suppression of emission from the resonators so as to provide detection and mass/electric charge analysis with good sensitivity and resolution.
