The development of impedance-based array devices is hindered by a lack ofrobust platforms and methods upon which to evaluate and interrogate sensors. One aspectto be addressed is the development of measurement-time efficient techniques forbroadband impedance spectroscopy of large electrode arrays. The objective of this workwas to substantially increase the low frequency impedance measurement th...
This article presents an overview of electrochemical sensors that employ nanomaterials and utilize electrochemical impedance spectroscopy for analyte detection. The most widely utilized nanomaterials in impedance sensors are gold (Au) nanoparticles and carbon nanotubes (CNTs). Au nanoparticles have been employed in impedance sensors to form electrodes from nanoparticle ensembles and to amplify ...
Electrochemical impedance spectroscopy (EIS) enables the examination of electrochemical nature electrodes and cells by applying an alternating voltage (or current) measuring resulting current voltage). The resistance capacitance components electrode can be evaluated AC changing frequency. In particular, analysis using equivalent circuit determine important parameters related to reaction electro...
