A potentiometric aspartame biosensor was fabricated by simply depositing the carboxylesterase (CES)-bonded poly(n-butyl acrylate-n-acryloxysuccimide) [CES-poly(nBA-NAS)] microspheres on a Ag/AgCl screen-printed pH selective electrode. The transducer made from non-plasticized polyacrylate membrane containing hydrogen ionophore and lipophilic salt. immobilized CES enzyme catalyzed enzymatic hydro...

Potentiometric multisensor systems were shown to be very promising tools for the quantification of numerous analytes in complex radioactive samples deriving from spent nuclear fuel reprocessing. Traditional multivariate calibration these is performed with partial least squares regression—an intrinsically linear regression method that can provide suboptimal results when handling potentiometric s...

This study compares between unmodified carbon paste (CPE; the paste has no ion pair) and polyvinyl chloride (PVC) membrane selective electrodes that were used in potentiometric determination of ketotifen fumarate (KTF), where sodium tetraphenylborate (NaTPB) was used as titrant. The performance characteristics of these sensors were evaluated according to IUPAC recommendations which reveal a fas...

Superconcentrated electrolytes, being highly thermodynamically nonideal, provide a stringent proving ground for continuum transport theories. Herein, we test an ostensibly complete model of LiPF6 in ethyl-methyl carbonate (EMC) based on the Onsager–Stefan–Maxwell theory from irreversible thermodynamics. We perform synchronous magnetic resonance imaging (MRI) and chronopotentiometry to examine h...

The explosive growth in the healthcare and lifestyle application has fueled recent research efforts to increase both integration and adaptability in biosensor readout design. Potentiometric sensor is emerging as important sensing devices in the areas of biomedical applications since the pioneer work on pH sensor has been introduced (Bergveld, 1970). It has appreciable advantages over traditiona...
