“…Electrochemical impedance spectroscopy is a nondestructive method that is sensitive enough to be used as a transducer of implanted biological sensors, , for pesticide sensing, − for inspection of food quality, − and for detection of DNA damage. , The use of impedance is competitive with other electrochemical techniques, with the detection limits being controlled by the type of electrode and the nature of the species to be determined. For example, a graphene-based electronic tongue showed a detection limit in the nanomole per liter range for the detection of organophosphate pesticides, with the possible discrimination between two pesticides .…”

Interpretation of impedance spectroscopy data requires both a description of the chemistry and physics that govern the system and an assessment of the error structure of the measurement. The approach presented here includes use of graphical methods to guide model development, use of a measurement model analysis to assess the presence of stochastic and bias errors, and a systematic development of interpretation models in terms of the proposed reaction mechanism and physical description. Application to corrosion, batteries, and biological systems is discussed, and emerging trends in interpretation and implementation of impedance spectroscopy are presented.

“…In fabrication of electrochemical sensors, it is usual to use a GCE as the platform of the sensor which can be modified by different modifiers to increase its sensitivity and selectivity and sometimes the GCE response is assisted by computerized programs to improve its performance [36][37][38][39][40][41][42][43][44][45][46][47][48][49][50][51][52][53][54]. Therefore, in this work we are going to fabricate a novel MIES based on electropolymerization of ATP onto AuPd NPs/PDA/MWCNTs-CS-IL/GCE.…”

In this work, a novel molecularly imprinted electrochemical sensor (MIES) has been fabricated based on electropolymerization of a molecularly imprinted polymer (MIP) onto a glassy carbon electrode (GCE) modified with gold-palladium alloy nanoparticles (AuPd NPs)/polydopamine film (PDA)/multiwalled carbon nanotubeschitosan-ionic liquid (MWCNTs-CS-IL) for voltammetric and impedimetric determination of cholestanol (CHO).Modifications applied to the bare GCE formed an excellent biocompatible composite film which was able to selectively detect CHO molecules. Modifications applied to the bare GCE were characterized by scanning electron microscopy (SEM), cyclic voltammetry (CV) and electrochemical impedance spectroscopy (SEM). Under optimal experimental conditions, the sensor was able to detect CHO in the range of 0.1-60 pM and 1-50 pM by EIS and DPV, respectively. Moreover, the sensor showed high sensitivity, selectivity, repeatability, reproducibility, low interference and good stability towards CHO determination. Our records confirmed that the sensor was successfully able to the analysis real samples for determination of CHO.

“…In this section, we have collected the results of the previous works published in the literature to compare our work with them and the information has been collected in Table 1. As can be seen, the biosensor proposed in this study was more stable than the reported biosensors by the previous works which may be related to integration of experimental and computational evidence to design and fabricate the biosensor as found by the previous works [52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64].…”

In this work, a novel biosensor was fabricated for detection of DNA damage induced by 4-nonylphenol (NP) and also determination of NP. To achieve this goal, a glassy carbon electrode (GCE) was modified with chitosan (Chit), gold nanoparticles (Au NPs) and DNA-multiwalled carbon nanotubes (DNA-MWCNTs). Then, the DNA-MWCNTs/ Au NPs/Chit/GCE was incubated with methylene blue (MB) to obtain MB-DNA-MWCNTs/Au NPs/Chit/GCE in which MB was used as the redox indicator. The modifications applied to the GCE were characterized by cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopic (EDS) and theoretical evidence. MB is a derivative of anthraquinone which can intercalate into double helix structure of DNA. By treating MB-DNA-MWCNTs/Au NPs/Chit/GCE with NP, a higher R ct was observed because the insertion of the NP may result in a more negative charge environment on the DNA surface which hinders accessibility of [Fe(CN) 6 ] 3-/4anion to the electrode surface. Change in the EIS response of the biosensor in the presence of NP was used to develop a novel system for monitoring the DNA damage induced by NP. The EIS technique was also used to develop a sensitive electroanalytical method for determination of NP.
