A micro-electrochemical time-of-flight technique relying on galvanostatic ion generation and potentiometric sensing (P-ETOF) has been developed in order to characterize dynamic properties of solid-state potentiometric sensors and to measure their capacitance. Lithographically-fabricated generator-sensor devices featuring 10 lm-wide micro-electrodes spaced by 20– 50 lm are used in either an open...

English) With a rising demand for low cost solutions to healthcare services, analysis, and toxicology, the Integrated Biosensor Platform developed by Acreo Swedish ICT and Linköping University, fills the gap where conventional sensors are not suitable. This report focuses the update of hardware and software in order to increase stability, introduce new sensors, and allow for wireless communicat...

Ultra-thin cobalt oxide (Co3O4) nanowires grown on gold coated glass substrates by the hydrothermal chemical deposition and have been used as a wide range dopamine potentiometric sensor. An anionic surfactant (sodium dodecylbenzenesulfonate) was used to achieve assisted growth procedure. Moreover, a polymeric membrane containing polyvinyl chloride as plasticized polymer, β-cyclodextrin as ionop...

Quality control of herbal medicines remain a challenging issue towards integrating phytomedicine into the primary health care system. As medicinal plants is a complicated system of mixtures, a rapid and cost-effective evaluation method to characterize the chemical fingerprint of the plant without performing laborious sample preparation procedure is reported. A novel research methodology based o...
