“…This concept has been recently explored in a bipolar electrochemical conguration, 125,126 with the [Ru(bpy) 3 ] 2+ /TPrA system, using degenerate Si bands or squares patterned in microuidic channels. [127][128][129] Degenerate SCs are also used in the area of HECL, 45,[130][131][132][133][134] a specic eld of ECL research in which an insulating oxide serves as a lter for hot electrons (electron of high thermal energy) generated in a conducting electrode (see Subsection 2.3). Owing to the planarity of Si and its ability to be conformably covered by its insulating oxide, n + -Si and p + -Si have been used to manufacture electrodes for HECL that were employed in immunoassays.…”

“…These added co-reactants generate oxidizing radicals upon one-electron reduction (e.g., peroxodisulphate, peroxodiphosphate or hydrogen peroxide) or in the case of azide, upon one-electron oxidation. Thus, both extremely strong oxidants and reductants are produced, and normally one-electron redox reactions not obtainable occur and the excitation of several types of label compounds are enabled [4,9].…”

“…Insulating polymer material surrounds the carbon black particles and enables electrons to be transported through the thin composite layer with very low IR-loss, and finally hot electrons to be emitted at the electrode/solution interface. The main advantage of these novel electrodes over traditional insulating thin-film covered electrodes is their insensitivity to composite layer thickness and composition of the film [9,15,21,22]. Compared to thin insulating film-coated electrode materials, such as aluminum or silicon, composite electrodes are found to have a more stable and reproducible HECL output in a wider pH range, and most importantly, without considerable background emission [15,23,24].…”

Novel hot electron-emitting working electrodes and conventional counter electrodes were created by screen printing. Thus, low-cost disposable electrode chips for bioaffinity assays were produced to replace our older expensive electrode chips manufactured by manufacturing techniques of electronics from silicon or on glass chips. The present chips were created by printing as follows: (i) silver lines provided the electronic contacts, counter electrode and the bottom of the working electrode and counter electrode, (ii) the composite layer was printed on appropriate parts of the silver layer, and (iii) finally a hydrophobic ring was added to produce the electrochemical cell boundaries. The applicability of these electrode chips in bioaffinity assays was demonstrated by an immunoassay of human C-reactive protein (i) using Tb(III) chelate label displaying long-lived hot electron-induced electrochemiluminescence (HECL) and (ii) now for the first time fluorescein isothiocyanate (FITC) was utilized as an a low-cost organic label displaying a short-lived HECL in a real-world bioaffinity assay.

The development of the hot electron-induced cathodic electrochemiluminescence (HECL) often accompanied with the advance in the electrode materials and instruments. In this work, dimethyl silicone oil was employed as the coating layer for initiating the HECL. The insulating layer was obtained by simple drop casting and subsequent polishing, which could withstand high voltage and meet the requirement of HECL. With the asprepared interface, the quantitative detection of puerarin in the aqueous solution was achieved based on the quenching effect on the SO 4 *À .
