Modern reaction-based indicator systems

다국어 초록 (Multilingual Abstract)

<P>Traditional analyte-specific synthetic receptors or sensors have been developed on the basis of supramolecular interactions (<I>e.g.</I>, hydrogen bonding, electrostatics, weak coordinative bonds). Unfortunately, this approach is often subject to limitations. As a result, increasing attention within the chemical sensor community is turning to the use of analyte-specific molecular indicators, wherein substrate-triggered reactions are used to signal the presence of a given analyte. This <I>tutorial review</I> highlights recent reaction-based indicator systems that have been used to detect selected anions, cations, reactive oxygen species, and neutral substrates.</P> <P>Graphic Abstract</P><P>This tutorial review describes current progress in the development of reaction-based indicators that show promise for use in detecting various anions, cations, reactive oxygen species, and neutral substrates.
