Sensing of Acetylcholine-Related Compounds Using Cation-Selective Electrodes

Ion-Selective Electrodes With Ionophore-Doped Sensing Membranes

At the time of this writing, more than 20 000 publications related to ion-selective electrodes (ISEs)1–7 have been published, with approximately two new ones per day in recent years. Figure 1 shows, for the period between 1970 and 2009, the continuing increase in the number of publications that could be readily recognized as reporting on the preparation or use of ionophore-based ISEs. Clearly, ...

A General Method for Selective Tritylation of Primary Hydroxyl Groups in Carbohydrates and Related Compounds

A general and rapid procedure is developed for the selective tritylation of the 'primary OH-function of the four common ribonucleosides, ascorbic acid, and polyhydric compounds. Silver ion was found to have a marked effect on tritylation reactions

Fibre Selective Neural Stimulation Using Intrafascicular Electrodes

Using a nerve stimulation model, areas of excitation can be calculated for different configurations of intrafascicular electrodes. Theory predicts fibre selectivity and recruitment order to depend on the electrode configuration used. This is verified by experiment. These experiments though also reveal two new phenomena indicating that the effect of a stimulus is influenced by preceding stimuli ...

Continuous monitoring using thiocyanate ion-selective electrodes

Electrochemical detection of sugar-related compounds using boron-doped diamond electrodes.

Electrochemical detection of sugar-related compounds was conducted using a boron-doped diamond (BDD) electrode as a detector for flow-injection analysis (FIA). Sugar-related compounds oxidize at high applied potentials, for which the BDD electrode is suitable for electrochemical measurements. Conditions for an FIA system with a BDD detector were optimized, and the following detection limits wer...
