Latest Patents

One of Hall's latest patents is a high sensitivity mechanical resonant sensor. This innovative system and method detect mass based on a frequency differential of a resonating micromachined structure, such as a cantilever beam. The cantilever beam is coated with an immobilized binding partner that couples to a predetermined cell or molecule. A first resonant frequency is determined for the cantilever with the immobilized binding partner. Upon exposure to a solution that binds with the binding partner, the mass of the cantilever beam increases. A second resonant frequency is then determined, and the differential resonant frequency provides the basis for detecting the target cell or molecule. The cantilever may be driven externally or by ambient noise. The frequency response of the beam can be determined optically using reflected light and two photodetectors or by interference using a single photodetector.
