  • Systems and methods for detection and quantitation of analytes using an oscillating stimulus
    Patent number: 9315855
    Abstract: Described systems and methods allow the detection of and determination of a concentration of a target analyte such as a biological cell, a virus, a polypeptide, a toxin, a pesticide, a drug, a drug residue, or a DNA strand, in a fluid sample. A variable stimulus, such as an oscillating magnetic field or a light beam of oscillating intensity, is applied to the sample, inducing variations in a position or shape of a constituent of the sample, or variations in a fluorescence of the sample. Such variations produce measurable variations in electric and/or optical properties of a sensor, variations which allow the determination of the concentration of the target analyte.
