Quantitative Electrolateral Flow Immunosensor (ELLI): Dengue Triage and Stroke Prognosis Case Studies

Sinawang P.D., Fajs L., Marks R.S., Ben-Gurion University of the Negev, IL

The development of a rapid, affordable, and sensitive diagnostic kit for point-of-care is important in most healthcare settings; however, only a few exhibit the needed quantitative capability. Our technology, ELLI, is a patented diagnostic device [...]

Electrochemically Exfoliated Graphene: Production and High Performances.

Wang J., Institute of Coal Chemistry, Chinese Academy of Sciences, CN

I’d like to present that graphene flakes have been produced with good properties and potentially used widely through electrochemical approaches. The electrochemically exfoliated graphene-based materials exhibit high performances in thermal management, electrocatalysis, supercapacitor, batteries and [...]

Establishment of a Matrix for Biorecognition Reactions based on Responsive Polymeric Compounds

Fandrich A., Buller J., Wischerhoff E., Laschewsky A., Lisdat F., Technical University of Applied Sciences Wildau, DE

Thermo-responsive polymers were synthesized and covalently bound to the surface of gold electrodes. Subsequently cyclic voltammetric and impedimetric measurements with so prepared working electrodes were realised in aqueous potassium ferro-/ferricyanide solutions at different temperatures. Significant [...]

Titanium Tungsten Coatings for Bioelectrochemical Applications

Wierzbicki R., Amato L., Lopacinska J., Heiskanen A., Emneus J., Boggild P., Molhave K., DTU Nanotech, DK

Our research interest is the combination of carbon nanotube electrochemistry with nanostructured substrates capable of cell scaffolding. Therefore, an adhesion / electric connection coating with good biocompatibility, PECVD compatibility and electrochemical stability needs to be [...]

Electrochemical Synthesis of Polyaniline Nanoparticles and Nanofibers

Xavier M.G., Leite E.R., Leite F.L., Leite E.R., Leite F.L., Venancio E.C., MacDiarmid A.G., Mattoso L.H.C., ARS-USDA, US

It is known that the properties of polymers produced by the electrodeposition of aniline is strongly dependent on the experimental conditions used. In these electrochemical methods two main steps can occur, the (1) nucleation process [...]

Integrated Microfluidic Device with an Electroplated Palladium Decoupler for Electrochemical Detection of the 8-hydroxydeoxyguanosine (8-OH-dG) DNA Adduct

Dawoud A.A., Kawaguchi T., Jankowiak R., Iowa State University, US

More sensitive and reliable microfluidic devices are needed for the detection of the 8-hydroxy-deoxyguanosine (8-OH-dG) DNA adduct, one of the most frequently used biomarkers reporting on oxidative stress. Therefore, we have developed a capillary electrophoresis [...]

Microchannel Immunoassays with Electrochemical Detection in Devices Constructed from Low Temperature Co-fired Ceramic and Screen Printed Gold

Fakunle E.S.O., Fritsch I., University of Arkansas, US

We report the first self-contained electrochemical enzyme linked immunosorbent assay in microchannel devices constructed from low temperature co-fired ceramic (LTCC) with screen-printed gold for fast and sensitive assays. No one has previously reported a device [...]

Carbon Nanofiber-Based Electrode Interface to Microbial Biofilms

McKnight T.E., Melechko A.V, Guillorn M.A., Merkulov V.I., Fleming J.T., Hensley D.K., Hullander E., McPherson J., Nivens D., Sayler G.S., Lowndes D.H., Simpson M.L., Oak Ridge National Laboratory, US

We report on the integration of bacterial biofilms with carbon nanofiber-based electrochemical systems to provide a robust biosensor platform. Biofilms are robust, self-packaged communities of whole cells that have attracted much attention due to their [...]
