Ion-selective electrodes are a routine tool of chemical analysis, characterized by beneficial analytical parameters, simple operation principle and low apparatus 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. However, in this case, a solid contact should be added between the substrate electrode and the membrane, enabling reversible charge transfer on the electrode / solid contact and solid contact / membrane interfaces. On the other hand, an advantageous alternative for membrane material, instead of poly(vinyl chloride), are 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 can be also obtained as microspheres, thus they can be introduced into a medium of low volume, e.g. living cells. The next step towards sensitivity increase and miniaturization is recording fluorescence intensity instead of absorbance, by using appropriate fluorophores, e.g. pyrene, and production of nanosensors, e.g. as micelles obtained from cross-linked alternative polymers. 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).
