A microbial biosensor was developed for the determination of phenolic compounds and the measurement was based on oxygen consumption in relation to analyte oxidation. Induced cells of Pseudomonas putida DSM 50026 were immobilised on the surface of SPG electrodes covered with cellulose acetate membrane by means of gelatine which was then cross linked with glutaraldehyde. The systems were calibrat...

Surfactant exfoliated 2D hexagonal Boron Nitride (2D-hBN) nanosheets are explored as a potential electrochemical sensing platform and evaluated towards the electroanalytical sensing of dopamine (DA) in the presence of the common interferents, ascorbic acid (AA) and uric acid (UA). Surfactant exfoliated 2D-hBN nanosheets (2-4 layers) fabricated using sodium cholate in aqueous media are electrica...

A novel electrochemical sensor was proposed for the determination of amitriptyline based on the copper oxide (CuO) nanoparticles modified graphite screen-printed electrode. CuO nanoparticles were used to enhance the surface area of the electrode and then improve the sensitivity of the electrochemical sensor. Amitriptyline electrochemical response characteristics of the modified electrode in a p...

A 3D non-enzymatic glucose disposable electrochemical sensor based on screen-printed graphite macroelectrodes (SPEs), modified with Ni, Cu, and Ni/Cu hydroxides, was prepared by a facile cost-effective method for the first time.

A new approach for incorporating metallic microwire electrodes into simple, self-pumping paperbased microfluidic devices is presented. The low resistance wire electrodes improve electrochemical response relative to screen-printed carbon electrodes. Here, for the first time, microwire electrodes have been incorporated into a self-pumping quasi-steady state flow paper-based microfluidic device ca...

Performance properties of lithium-ion battery electrodes; capacity, rate and lifetime, are determined by the design coating composite microstructure. The internal pore structure electronic networks for high coat weight graphite electrodes manipulated through changes in ink rheological properties, an syringe dispensing printing process. a water-based, viscosity were optimised using secondary sol...

The pulsed polarization technique on solid electrolytes is based on alternating potential pulses interrupted by self-discharge pauses. Since even small concentrations of nitrogen oxides (NOx) in the ppm range significantly change the polarization and discharge behavior, pulsed polarization sensors are well suited to measure low amounts of NOx. In contrast to all previous investigations, planar ...
