Special Issue Information

Dear Colleagues,

Impedance spectroscopy is a key enabling measurement method for a range of related applications that exploit the measurement of the complex impedance of a material or a material system to characterize it or its change in dependence of time or of a certain measurement quantity within it or its environment.

The method is often used in several sectors of science and technology, ranging from the classical material characterization to the characterization of nanocomposite materials and corrosion. In the characterization of energy storage units, it effectively allows a deep insight into closed storage units without charging or discharging it. One further advantage of the method is its non-invasiveness, which enables its use for in vitro and in vivo bio- and medical applications. At present, several sensor principles make use of impedance spectroscopy to improve measurement accuracy or to acquire more information from a sensor.

This Special Issue aims at putting together recent advancements in fundamentals, understanding, and applying impedance spectroscopy. It aims to outline some future scientific challenges in the field of impedance spectroscopy. Contributions from all fields of impedance spectroscopy, either experimental or theoretical studies, as well as potential technical implementations, are welcome. We welcome contributions in the fields of:

  • Material testing and characterization;
  • Corrosion and coatings;
  • Sensors, biosensors, and electrochemical sensors;
  • Energy storage, batteries, and capacitors;
  • Bio- and medical applications;
  • Food and nutrition.

The physicochemical characterization of pharmaceutical materials is essential for drug discovery, development and evaluation, and for understanding and predicting their interaction with physiological systems. Amongst many measurement techniques for spectroscopic characterization of pharmaceutical materials, Electrical Impedance Spectroscopy (EIS) is powerful as it can be used to model the electrical properties of pure substances and compounds in correlation with specific chemical composition. In particular, the accurate measurement of specific properties of drugs is important for evaluating physiological interaction. The electrochemical modelling of compounds is usually carried out using spectral impedance data over a wide frequency range, to fit a predetermined model of an equivalent electrochemical cell. This paper presents experimental results by EIS analysis of four drug formulations (trimethoprim/sulfamethoxazole C14H18N4O3-C10H11N3O3, ambroxol C13H18Br2N2O.HCl, metamizole sodium C13H16N3NaO4S, and ranitidine C13H22N4O3S.HCl). A wide frequency range from 20 Hz to 30 MHz is used to evaluate system identification techniques using EIS data and to obtain process models. The results suggest that arrays of linear R-C models derived using system identification techniques in the frequency domain can be used to identify different compounds. Full article

Immunoassay plays an important role in the early screening and diagnosis of diseases. The use of electrochemical methods to realize the label-free, specific and rapid detection of antigens has attracted extensive attention from researchers. In this study, we realized the function of immunosensing and detection by lithography, the interdigitated gold electrode on the polyethylene naphthalate (PEN) membrane. Then, the gold electrode was biofunctionalized and the characterization was verified by atomic force microscopy, which was finally for the detection of mice IgG. This immunosensor has a low detection limit, with a broad linear detection range of 0.01–10 ng/mL. The results show that the electrochemical impedance sensor made of metal electrodes based on PEN flexible materials is suitable for immunoassay experiments. If this method could be proved by further studies, broad application prospects can be seen in routine immunoassays. Full article
