NANOPARTICLE DERIVATIZATION OF TARGETS FOR DETECTING AND DETERMINING THE CONCENTRATIONS OF TARGETS BY IMPEADANCE-SPECTROSCOPY-BASED SENSORS

摘要

Embodiments of the present invention are directed to for detecting the presence and concentration of one or more particular target molecules in solutions, air or other gasses, or otherwise present in an environment or sample, by impedance-spectroscopy-based sensors. Various embodiments of the present invention provide for derivatizing target molecules with nanoparticles to increase capacitance changes at electrode surfaces in order to generate stronger signals and improve signal-to-noise ratios of impedance-spectroscopy-based sensors.
