Local Electrochemical Impedance Spectroscopy (LEIS) is an emerging discipline in the field of electrochemical research. It is based on the widely accepted Electrochemical Impedance Spectroscopy (EIS) technique, a powerful method to determine reaction mechanisms on macroscopic electrodes. When however the electrode represents a heterogeneous behavior, local information is indispensable. This pro...

Neurons release neurotransmitters in a process called exocytosis, wherein packets of transmitter molecules are released from the cells upon stimulation. Adrenal chromaffin cells, which also undergo exocytosis, constitute a model system for neuronal release. Quantal release of adrenaline from chromaffin cells can be measured using the electrochemical technique of amperometry, historically employ...

In this paper we introduce a blanket mold imprinting process to prevent complication of the fluid flow and difficulties in producing high pressure seals. Inchannel embedded metal lines were also fabricated within the channel allowing electrochemical detections of analytes. Electrochemical microfluidc device has been fabricated on the PET (Polyethylene Terephthalate) substrate by using imprintin...

OBJECTIVES To evaluate and validate a hand-held electrochemical meter (Precision Xtra®) as a screening test for subclinical ketosis and hypoglycaemia in lactating dairy cattle. DESIGN Method comparison study using a convenience sample. PROCEDURE Blood samples were collected into plain tubes from the coccygeal vessels of 181 Holstein cows at 2-4 weeks of lactation during summer in Iran. Bloo...

A bifunctional molecular linker containing both aryl diazonium and trioxolane groups was synthesised and its ability to sequentially functionalise glassy carbon and covalently immobilise heme investigated. Functionalisation was demonstrated by electrochemical techniques.

High throughput electrochemical techniques are widely applied in material discovery and optimization. For many applications, the most desirable electrochemical characterization requires a three-electrode cell under potentiostat control. In high throughput screening, a material library is explored by either employing an array of such cells, or rastering a single cell over the library. To attain ...
