Abstract
In various aspects are provided a microfluidic and/or nanofluidic sensor that can provide an indication of the reliability of its measurement of the presence of an analyte in a sample under investigation, an analyte concentration in the sample under investigation, or both. The provided sensors, microfluidic devices, and methods of analyte detection, utilize two transduction mechanisms from the same molecule to determine analyte presence, analyte concentration, or both. An analyte sensing molecule is used that can provide both an optical signal and electrochemical signal when an analyte is recognized by an analyte binding portion of the sensing molecule.
