It’ all in the membrane: The applicability of emission readout of ion-selective electrodes, containing fluorimetrically active polyoctylthiophene (POT) in the membrane, operating under chronopotentiometric mode was studied. The electrochemical and optical signals were collected in the same experiment and compared. Recorded signal potential or emission changes in time resulted in transition times, that were dependent on analyte concentration in solution. Optically read transition times were shorter than those observed electrochemically.

在计时电位条件下运行的离子选择性电极信号的荧光读数

一切都在膜中：研究了离子选择性电极的发射读数的适用性，该电极在膜中含有荧光活性聚辛基噻吩 (POT)，在计时电位模式下运行。在同一实验中收集电化学和光信号并进行比较。随时间记录的信号电位或发射变化导致转换时间，这取决于溶液中的分析物浓度。光学读取转换时间比电化学观察到的要短。
