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 ...

A survey and review of recent patents on electrochemical methods for corrosion monitoring from 1999 to 2009 are presented in this paper. The patents were classified into 4 groups according to different electrochemical theories, which are potential, polarization, electrochemical impedance and electrochemical noise. A future outlook of the development on new research aspects particularly on metho...

physiological processes, much effort has been devoted to the development of methods for detecting glucose in food and biological matrices. However, the development of direct methods has been hindered by the lack of a suitable chromophore or electrophore, and hence more complicated methods have been adopted for glucose determination. Two of these methods, pulsed amperometric determination and en...

Simultaneous acquisition of in vivo electrophysiological and neurochemical information is essential for understanding how endogenous neurochemicals modulate the dynamics of brain activity. However, up to now such a task has rarely been accomplished due to the major technical challenge of operating two independent recording systems simultaneously in real-time. Here we propose a simpler solution ...
