The Effect Of Ion-Pairing On The Open Circuit Potential Of 3-Mercaptoproprionic Acid Modified Gold Electrodes, Mark Anderson, Alice Harper
Mark R. Anderson
Open circuit potential (OCP) measurement is used to monitor the charge of a monolayer of 3-mercaptopropionic acid. OCP is determined by the concentrations of the reduced and oxidized forms of a redox couple in the solution adjacent to the modified interface. OCP values were monitored in the presence of the one-electron redox couple Fe(CN)63-/4- as a function of solution pH. The OCP measured at basic pHs was different from the acidic OCP due to differences in electrostatic interactions between the interface and the redox species as described by the Nernst equation. The influence of ion-pairing with the monolayer is studied …

Impedance Of Contact-Printed Alkanethiol Self-Assembled Monolayers On Gold, Leslie Adamczyk, Mark Anderson

Contact printing (CP) is a common method for creating modified interfaces having two-dimensional patterns. The popularity of this method is due to the ease and low cost of this method. When printing an interfacial pattern with n-alkanethiols, the desired properties are those of a homogeneous, solution deposited monolayer. Patterning a surface, however, may cause defects to occur within the monolayer where two thiol domains meet. If large enough, the activity of these areas can dominate the electrochemical response. Creating patterned monolayer modified interfaces, therefore, may generate vast user defined domain boundaries that impact the electrochemical behavior of the modified interface …

Preparation of interfacial structures by molecular self-assembly has been actively studied for many years. Well-defined modified interfaces can be used to study fundamental interfacial properties, or they can be used in different practical applications. To broaden the utility of interfaces prepared by molecular self-assembly, monolayers containing terminal functionality are frequently used. These interfaces have structural and physical properties that can be controlled by both the identity of the functionalization as well as the ensemble structure of the modified interface. This suggests that the chemical and physical properties of an interface can be designed and/or controlled to some extent by altering …
