Silk biocomposites as flexible and biodegradable electrochemical sensors

Pal R.K., Yadavalli V.K., Virginia Commonwealth University, US

The convergence of naturally derived and synthetic polymers provides exciting opportunities to develop physiologically compliant bioelectronics systems. The combination of silk proteins and poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT:PSS) enables the formation of functional biocomposites with unique properties. [...]

Modeling and simulation of organic MEM relay for estimating the coefficient of thermal expansion of PEDOT:PSS

Khan N.Z., Rutgers University, US

PEDOT:PSS is becoming a popular transparent electrode material for organic electronic and optoelectronic devices, replacing the more commonly used Indium Tin Oxide (ITO). PEDOT: PSS has good conductivity, transparency, superior electrical and thermal stability and [...]

Novel sensing device based on potentiometric measurement for the detection of lithium

Merzouk S., Zine N., Tahajanan M., Agouzoul M., Bausells J., Teixidor F., Jaffrezic-Renault N., Errachid A., Institut des Sciences Analytiques, FR

The therapy of manic depressive psychosis with lithium salts requires periodic measurements of the Li concentration in whole blood, plasma, urine or serum. The analysis is difficult because of the low lithium concentration compared to [...]

A Novel Conducting Polymer for Biosensor Applications

Soylemez S., Ekiz Kanik F., Ileri M., Ozdemir Hacıoglu S., Toppare L., Middle East Technical University, TR

In this study, 2-(4-fluorophenyl)-4,7-di(thiophene-2-yl)-1H-benzo[d]imidazole, a novel monomer, was synthesized and its polymer was used for the immobilization matrix for cholesterol oxidase (ChOx). A novel cholesterol biosensor was generated. The designed conducting polymer based biosensor showed [...]

Carbon Microstructures for Glucose Biosensor

Xu H., Malladi K., Wang C., Madou M.J., University of California Irvine, US

In this work we report on a novel design and fabrication of glucose sensor based on carbon post electrode array. Apart from the fact that carbon has a wide electrochemical stability window, one advantage of [...]

Cationic Polythiophene for Label-Free, Colorimetric and Fluorometric Detection of DNA

Ho H.-A., Leclerc M., Université Laval, CA

In order to respond to new demands and needs in modern medical diagnostics and biomedical research applications, a lot of new DNA detection approaches have been reported. However, most of these methods have the disadvantage [...]
