An alternative optical signal transduction mechanism for ion-selective optodes is proposed. The nanostructural sensors benefit from ion-selective reversing aggregation caused quenching yielding turn-on, bright and highly stable optical signals. Selective incorporation of analyte results in transformation of the polymer dye from aggregate to a micelle structure, affecting spatial arrangement of chromophore groups in the nanostructure. Formation of micelles, induced by ion-selective interactions, is coupled with pronounced increase of emission due to decrease of aggregation caused quenching, characteristic for dispersed phase formation. The formed micelles are highly stable in solution, offering constant in time (days scale) emission signal. The important difference from other known systems is that the analyte binding induced change does not affect the chromophore group, but occurs in distant, terminal position of the side chain of the polymer.

As a model system calcium selective optodes have been prepared. Thus obtained probes were characterized with broad analyte concentration range (from 10⁻⁷ to 10⁻³ M) emission signal increase. The turn-on response was observed within broad range of pH (6.3–8.9), with no sign of optical signal deterioration during 5 days contact with the analyte or more than two weeks storage.

提出了用于离子选择光电二极管的另一种光信号转导机制。纳米结构传感器受益于离子选择性反向聚集，该聚集引起淬灭，从而产生开启，明亮和高度稳定的光学信号。分析物的选择性掺入导致聚合物染料从聚集体转变为胶束结构，从而影响纳米结构中发色团的空间排列。由离子选择性相互作用引起的胶束的形成，由于团聚的减少引起的猝灭而明显增加了发射，猝灭是分散相形成的特征。形成的胶束在溶液中高度稳定，提供恒定的时间（天标度）发射信号。

作为模型系统，已经制备了钙选择性光电二极管。如此获得的探针具有宽的分析物浓度范围（从10 ^-7到10 ^-3  M）发射信号增加。在较宽的pH（6.3-8.9）范围内观察到开启响应，在与分析物接触5天或保存两周以上的过程中，没有光信号恶化的迹象。
