Jonoselektywne sensory potencjometryczne i optyczne: Ion-sective potentiometric and optical sensors: Ion-selective electrodes are a routine tool of chemical analysis, characterized by beneficial analytical parameters, simple operation principle and low jonoelektywne cost.

In this group of sensors particularly advantageous are those with plastified poly- vinyl chloride based membranes, containing ionophore — interacting selectively with some cations [1].

From the practical point of view all-solid-state constructions became very useful. On the other hand, an advantageous alternative for membrane material, instead of poly vinyl chlorideare polyacrylates which can be easily obtained by photopolymerization and provide lower detection limits due to lower ion mobility in the membrane.

Membranes of similar composition containing ionophore can be also applied in ion-selective optodes, where a solid contact is not needed, but additional membrane component is a dye chromoionophore of different colours of the protonated and deprotonated forms.

Such optodes elektroxy be also obtained as microspheres, thus they can be introduced into a medium of low volume, e. slektrody

The next step towards sensitivity increase and miniaturization is recording fluorescence intensity instead of absorbance, by using appropriate fluorophores, e. Appropriate modification of the surface phase of such nanosensors, affecting the permeability of analyte ions into the nanospheres, enables tailoring of the shape of analytical characteristics — from sigmoidal high sensitivity, narrow linear response range to linear dependence of the signal on logarithm of analyte concentration low sensitivity, but wide linear response range.
