Chemically diverse modified electrodes: A new approach to the design and implementation of sensor arrays

Eine chemisch modifizierte Platinelektrode als zweizähniger Diaminligand zur Bildung wohldefinierter immobilisierter Bis(η1‐P‐ether‐phosphan)(diamin)ruthenium(II)‐Komplexe

“…Chemisch modifizierte Elektroden (CMEs)7 mit gebundenen aktiven Zentren sind eine besondere Art von Interphasen. Sie werden in verschiedenen Bereichen wie der Katalyse,8 bei analytischen Anwendungen9 und in der Sensorik10 eingesetzt. Neben anderen Methoden7 wurde für die Immobilisierung metallorganischer Verbindungen11 die kovalente Verankerung auf einer metallischen Elektrode über Siloxan‐Spacer eingesetzt 12…”

Formation of n-Alkanethiolate Self-Assembled Monolayers onto Gold in Aqueous Micellar Solutions of n-Alkyltrimethylammonium Bromides

“…25 The ability to inhibit and even prevent SAM formation with applied potentials in this aqueous process is remarkable and has attractive utility in the selective modification of electrode arrays that can impact applications in chemical sensing. 26,27 The results in Figure 7a suggest that displacement of counterions is the rate-limiting step in the formation of alkanethiolate SAMs in aqueous micellar solutions of C m -TAB. To test this hypothesis, we investigated the effect that a small concentration of potassium iodide (KI) exhibited on the rates of C 10 S SAM formation in 32 mM C 12 -TAB(aq).…”

A Chemically Modified Platinum Electrode as a Bidentate Diamine Ligand for Forming Well‐Defined, Immobilized Bis(η1‐P‐ether phosphane)(diamine)ruthenium(II) Complexes

“…Chemically modified electrodes (CME)7 with anchored active centers are a special type of interphase. Such devices are widely applied for catalysis,8 analytical applications,9 and sensor construction 10. Among other techniques,7 covalent bonding through a siloxane spacer to a metallic electrode11 has been successfully employed for immobilization of many organometallic compounds 12…”
