Rochat, SébastienSeverin, Kay2010-04-242010-04-242010-04-24201010.2533/chimia.2010.150https://infoscience.epfl.ch/handle/20.500.14299/49659WOS:000276613600009Simple but powerful chemosensors were developed by taking advantage of self-assembly processes. First, we will describe a turn-on fluorescent sensor for the pharmacologically important lithium ion. The sensor can be used in purely aqueous solution, and it displays a very high selectivity for lithium over sodium and magnesium ions. It is based on a metallacrown receptor unit, which can be assembled in situ from simple building blocks. Furthermore, we will describe a cross-reactive sensor array for the detection of small peptides. The individual sensors of the array are formed by mixing metal complexes with fluorescent dyes.Fluorescence spectroscopyIndicator displacement assayLithiumPeptideSensortext::journal::journal article::research article
