Ionophores for potentiometric and optical sensors

Article Abstract:

Individual carrier-based ion-selective electrodes and bulk optides are characterized. Selectivity coefficients were determined by a number of methods, including fixed interference, matched potential, mixed solution and separate solution. The characterization of the response mechanism of optodes were based on Valinomycin and the alkyl-acridine orange derivative called Ind-2. A number of sensors were also determined for NH4+ as an alternative response mechanism.

Radionuclide sensors for environmental monitoring: from flow injection solid-phase absorptiometry to equilibration-based preconcentrating minicolumn sensors with radiometric detection

Article Abstract:

Radionuclide sensors for [alpha]- and [beta]-emitting radionuclides, which have combined selective sorption with a radiometric detection method, and minicolumn sensors for radionuclide detection are described. This method is used for studying binding interactions of biologically relevant compounds by using microspheres and radiolabeled molecules of high specific activity and it is designed for discriminating between bound and unbound molecules.
