There is not much known on the stability of plasticized polymeric sensor membranes against ionizing radiation. While recent studies have indicated applicability potentiometric sensors with such for quantification actinides and lanthanides in spent nuclear fuel reprocessing solutions, real industrial application will require their radiation fields. The present study explores this problem evaluat...

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...

The spectroscopic and proton- and Zn(II)-binding properties of two new members of the Zinpyr family of fluorescent sensors are reported. In ZP1B and ZP3B, a (2-picolyl)(4-picolyl)amine (2,4-DPA) moiety is installed in place of the di(2-picolyl)amine (2,2-DPA) ligand used in the parent sensors ZP1 and ZP3. This modification has the benefit of both lowering the proton-induced turn-on at physiolog...

The construction and general performance of thirteen new polymeric membrane sensors for the determination of fexofenadine hydrochloride based on its ion exchange with reineckate, tetraphenylborate and tetraiodomercurate have been studied. The effects of membrane composition, type of plasticizer, pH value of sample solution and concentration of the analyte in the sensor internal solution have be...

Many research studies have been conducted on the use of conjugated polymers in the construction of chemical sensors including potentiometric, conductometric and amperometric sensors or biosensors over the last decade. The induction of conductivity on conjugated polymers by treating them with suitable oxidizing agents won Heeger, MacDiarmid and Shirakawa the 2000 Nobel Prize in Chemistry. Common...

Potentiometric sensors are widely used in the construction of automatic and automated process control systems. In potentiometric sensors, resistance is output signal its magnitudes depend on magnitude input signal. voltage, current, digital code, angle rotation, displacement or other usually as practice, task simulating which coming from built-in sensor often appeared. An additional can be to s...
