摘要： The presence of biomarkers or other analytes can be detected in the bodily fluid using Electrochemical Impedance Spectroscopy (EIS) or Electrochemical Capacitance Spectroscopy (ECS) in devices, such as handheld point-of-care devices. The devices, as well as systems and methods, utilize using Electrochemical Impedance Spectroscopy (EIS) or Electrochemical Capacitance Spectroscopy (EIS) in combination with an antibody or other target-capturing molecule on a working electrode. Imaginary impedance or phase shift, as well as background subtraction, also may be utilized.

摘要： Methods for detecting one or more analytes in a sample utilizing Electrochemical Impedance Spectroscopy (EIS) measurement. In one method, analyte detection includes comparing an imaginary impedance measurement to a calibration curve of concentrations for each target analyte. The calibration curve of concentrations for each target analyte is established at an optimal frequency. In another method, a signal decoupling algorithm is utilized for detection of more than one analyte on an electrode.

摘要： Osmolality and osmolality sensors and methods utilizing electrochemical impedance to detect changes in impedance to varying salinity concentrations. By way of example, the impedance reported at the specified frequency varies logarithmically with the concentration of sodium chloride subject to the sensor surface. Measurements obtained by the sensors and methods herein are utilized, for example, to differentiate between the clinical stages of dry eye disease (290-316 mOsm/L) to complement the current diagnostic procedures. Blood serum, urinalysis, and saliva also may be tested and the corresponding osmolarity or osmolality level evaluated for indications of a disease or condition.
