Carbon Particle-Doped Polymer Layers on Metals as Chemically and Mechanically Resistant Composite Electrodes for Hot Electron Electrochemistry

This paper presents a simple and inexpensive method to fabricate chemically mechanically resistant hot electron-emitting composite electrodes on reusable substrates. In this study, the electron emitting were manufactured by doping polymer, nylon 6,6, with few different brands of carbon particles (graphite, black) coating metal substrates aforementioned ink layers carbon-polymer mass fractions. The optimal fractions in these allowed that can inject electrons into aqueous electrolyte solutions clearly generate electron-induced electrochemiluminescence (HECL). An aromatic terbium (III) chelate was used as probe is known not be excited basis traditional electrochemistry but efficiently electrically presence hydrated during injection solution. Thus, hot, pre-hydrated or at close vicinity electrode surface monitored HECL. study shows extreme pH conditions could damage present electrodes. These low-cost, simplified robust thus demonstrate they HECL bioaffinity assays other applications electrochemistry.
