Chemically modified electrodes consist of electroactive monolayers as well as thicker films deposited on conductive substrates. Chemically modified electrodes possess unique properties compared to the non-modified ones. The application of chemically modified electrode surfaces with electroanalytical methods, especially voltammetry, offer the advantages of fast, portable, low-cost, sensitive, simple, and accurate alternatives in chemical analysis.
This Special Issue aims to report the development of the types as well as the basic principles and the way of making the electroactive monolayer layers, as well as the thicker films deposited on substrate conductors, which are commonly referred to as chemically modified electrodes, and their successful application in chemical analysis and problem solving in complex analytical problems.
This field of electroanalysis has been very active in recent years, and there are many review articles dealing with the construction, characterization, and electrochemical behavior of chemically modified electrodes.
Usually, to improve sensitivity and selectivity, electrodes are modified with carbon-based nanomaterials, such as multiwalled carbon nanotubes (MWCNTs), or metal nanoparticles (NPs), such as AuNPs, PtNPs, and AgNPs.
Meanwhile, conducting polymers (CP) are also of interest for their use as sensitive electrode surface coatings on electrochemical sensors and biosensors (electrode surface modifiers). They exhibit large electrical conductivity and satisfying electrochemical reversibility and can therefore be applied in sensor transducer signaling. Furthermore, CPs can be chemically acquired functional groups, which act as "tags" because of their ability to identify biological or chemical items. Recent trends in chemically modifying electrodes are building high-specific CP recognition points, which will strengthen selectivity and advance the sensitivity of the nidification procedure. In connection with the specificity of the process, molecularly imprinted polymers (MIPs) can be administered in the synthesis of polymers with predetermined molecular recognition features and can be used in constructing sensors and biosensors. Molecular imprinting is the innovation of these designs, as they enjoy plentiful improved traits: they are sensible, fast, simple, and can be portable.
The main goal of this Special Issue is to attract the attention of distinguished scholars carrying out intensive research in the field of electrochemical biosensing and voltammetry based on modified electrodes.
