Electrochemical Methods and Sensors for Characterization of Biological,Pharmaceutical and Polymeric Nanomaterials

摘要

This paper examines the application of multi-frequency / multi-electrochemical potential Electrochemical Impedance/Dielectric Spectroscopy to analysis of biological, pharmaceutical and polymeric nanomaterials and nanocomposites. Our research focuses on establishing a relationship between chemical composition and properties of nanomaterials and their electrochemical characteristics. Advanced twenty first century materials must often be evaluated at nano-particle and molecular levels. Their properties often change with time resulting in less accurate understanding of chemical and biological systems. To address this problem, development of fast screening methods and/or on-line sensors based on these methods is required.
