The goal of our project is to pattern well-defined electrodes from single-layer graphene for use in electrochemistry investigations. We have fabricated devices using both mechanically exfoliated graphene and chemical vapor deposition (CVD) graphene. Preliminary experimental data show that the graphene is chemically clean, based on measurements that the effective area of the electrodes determine...

Electrochemistry, biosensors and microfluidics are popular research topics that have attracted widespread attention from chemists, biologists, physicists, and engineers. Here, we introduce the basic concepts and recent histories of electrochemistry, biosensors, and microfluidics, and describe how they are combining to form new application-areas, including so-called "point-of-care" systems in wh...

Rare examples of tetrapalladated derivatives in which two flat tetradentate bridging ligands are perfectly face-to-face as a result of a remarkable ancillary ligand effect are reported.

For the first time, a glucose oxidase-functionalized bioconjugate was prepared and served as a new trace label through its direct electrochemistry and electrocatalysis in a sandwich-type electrochemical aptasensor for ultrasensitive detection of thrombin.

Research activities in the field of imidazole-derived push-pull systems featuring intramolecular charge transfer (ICT) are reviewed. Design, synthetic pathways, linear and nonlinear optical properties, electrochemistry, structure-property relationships, and the prospective application of such D-π-A organic materials are described. This review focuses on Y-shaped imidazoles, bi- and diimidazoles...

The two-dimensional polymerization and reaction at the solid/liquid interface has caused considerable attention in recent years because of its fundamental importance and many potential applications. Scanning tunneling microscopy (STM) provides the possibility for the observation and manipulation of polymerization and reaction occurring at the solid/liquid interface at the atomic level. Two-dime...

Microbial bioelectrochemical systems (BESs) utilize living microorganisms to drive oxidation and reduction reactions at solid electrodes. BESs could potentially be used at municipal wastewater treatment plants (WWTPs) to recover the energy content of organic matter, to produce chemicals useful at the site, or to monitor and control biological treatment processes. In this paper, we review bioele...

In situations involving large potentials or surface charges, the Poisson-Boltzman (PB) equation has shortcomings because it neglects ion-ion interactions and steric effects. This has been widely recognized by the electrochemistry community, leading to the development of various alternative models resulting in different sets "modified PB equations," which have had at least qualitative success in...
