Journal ArticleDOI
Direct evidence of ionic fluxes across ion-selective membranes: a scanning electrochemical microscopic and potentiometric study.
Róbert E. Gyurcsányi,Éva Pergel,Renáta Nagy,Imre Kapui,Bui Thi Thu Lan,Klára Tóth,István Bitter,Ernö Lindner +7 more
TL;DR: The amperometrically determined surface concentrations correlated well with the lower detection limits of the lead ion-selective electrodes.
Journal ArticleDOI
Novel potentiometric and optical silver ion-selective sensors with subnanomolar detection limits
Zsófia Szigeti,Adam Malon,Tamás Vigassy,Viktor Csokai,Alajos Grün,Katarzyna Wygladacz,Nan Ye,Chao Xu,Vincent J. Chebny,István Bitter,Rajendra Rathore,Eric Bakker,Ernö Pretsch +12 more
TL;DR: Ten Ag+-selective ionophores have been characterized in terms of their potentiometric selectivities and complex formation constants in solvent polymeric membranes and the compounds with pi-coordination show much weaker interactions than those with thiocarbamate groups as the coordinating sites.
Journal ArticleDOI
Solid-State Ion Channels for Potentiometric Sensing†
Journal ArticleDOI
A novel polymeric membrane electrode for the potentiometric analysis of Cu2+ in drinking water
Zsófia Szigeti,István Bitter,Klára Tóth,Christopher Latkoczy,Daniel Fliegel,Detlef Günther,Ernö Pretsch +6 more
TL;DR: Based on a novel ionophore, an ion-selective electrode has been developed for the determination of Cu 2+ in drinking water as discussed by the authors, and its selectivity behavior is characterized and its lower detection limit optimized for measurements with different electrolyte backgrounds.
Journal ArticleDOI
Ionophore–gold nanoparticle conjugates for Ag+-selective sensors with nanomolar detection limit
Gyula Jágerszki,Alajos Grün,István Bitter,Klára Tóth,Róbert E. Gyurcsányi,Róbert E. Gyurcsányi +5 more
TL;DR: This work reports on the synthesis and trace analytical application of ionophore-gold nanoparticle conjugates as a basis of a new concept in confining ionophores to ion-selective membranes using inert nanoparticle carriers.
