“…Also, they are very efficient in the electron transfer and capacitance control of an electrode [115]. SAMs can be described as an elegant method by which we can address electrically a molecular component [126,127]. The method by which the SAMs were formed is the spontaneous adsorption of self-assembled molecules on metals like Au, Ag, Cu, Zn, Fe, Ni, glass, or Pt [130][131][132].…”

Self-assembled monolayer (SAM) represents one of the methods to precisely modify surface structures in the nanoscale dimension. It has opened up a new era of exploration and has a profound impact on sensors and biosensors due to its unique properties. Different self-assemblies will be considered in this chapter: SAM of metallic nanoparticles on polymeric film, SAM of surfactant on polymeric film, and SAM of S-containing compounds on nanometallic films. The main goal of this chapter is to present comprehensive collection of the recent achievements in this area. Several issues will be discussed including the morphology, sensitivity, selectivity, stability, and electrochemical properties of the sensor.

“…Then the electrode was washed carefully with distilled water to remove nonadsorbed materials and afterwards was dried at room temperature. In order to get the electrode modified with 4-formylphenylboronic acid (BA/AHMP/Au electrode) the AHMP/Au electrode was treated with 1,4-dioxan saturated with 4-formylphenylboronic acid solution (BA) at 50 8C for 60 minutes [20,28,30]. The illustration of stepwise formation of the SAM on the gold electrode surface is shown in Scheme 1.…”

A self-assembled monolayer (SAM) modified by 4-formylphenylboronic acid was formed on the gold electrode, which was applied for the determination of trace concentrations of Cu(II). The formation of advanced SAM on the gold electrode was evidenced by electrochemical impedance spectroscopy, atomic force microscopy and contact angle measurements. Electrochemical determination of Cu(II) ions was performed by square wave voltammetry. Some mutual interferences caused by Cd(II), Co(II), Fe(II), Ni(II) and Pb(II) ions were investigated and it was demonstrated how the negative effects of these interfering ions could be eliminated by adjustment of proper parameters of square wave voltammetry.

“…It is reasonable to assume that the formation of cyclic esters upon binding with sugars modifies the redox properties of an electroactive system chemically modified with PBA. In this regard, electrochemical assays employing PBAs have been proposed and based on two options: surface immobilized processes, [ 34,35 ] and solution phase processes. In solution, the introduction of ferrocene (Fc) connected directly [ 36,37 ] or indirectly [ 29,38–41 ] to PBA is a fascinating approach.…”

The aim of the present paper is to highlight a novel electrochemical assay for an extremely‐selective detection of fructose thanks to the use of a supramolecular complex between β‐cyclodextrins (β‐CDs) and a chemically modified ferrocene with boronic acid named 4‐Fc‐PB/natural‐β‐CDs. Another kind of β‐CDs, the 4‐Fc‐PB/3‐phenylboronic‐β‐CDs, is proposed for the detection of glucose. The novel electrochemical probe is fully characterized by 1H nuclear magnetic resonance, mass spectroscopy, and elemental analysis, while the superior electrochemical performance is assessed in terms of sensitivity and detection limit. The novelty of the present work consists in the role of CDs that for the first time are employed in electrochemistry with a unique detection mechanism based on specific chemical interactions with the target molecule by the introduction of proper binding groups. A highly selective detection of fructose is obtained and it is believed that the proposed mechanism of detection represents a new way to electrochemically sense other molecules by varying the combination of specific groups of the supramolecular complex. The findings are of impactful importance since a quick, easy, cheap, and extremely selective detection of fructose is not yet available in the market, here achieved by using electrochemical methods which are a very growing field.
