The electrostatic resonators of bridge, cantilever and comb type or piezoelectric resonators with detection electronics are key components of chemical, biological, biochemical and biomedical sensors with sensitivity down to the single molecule detection of ligands. The detection electronics relies on measurement of frequency changes of resonators using phase or signal comparator. The large arrays of these sensors with individual or common sensing circuitry improve detection sensitivity, selectivity and lower incidence of false positives and negatives. |
