| Popis: | Large size odd-numbered calixarenes were used for the first time as ionophoric agents for the functionalization of ISFET microsensors and EIS structures through thermal evaporation process. Both calixarenes have shown a nernstian sensitivity over three decades towards only copper (II) activities. Very low selectivity coefficients were observed for K + and Ca 2+ whereas Cd 2+ and Pb 2+ (less than 10 −3 ) can be considered as interfering ions. Lifetime of around three months for the microsensors were obtained. |
