Partitioning Indicator Displacement Assay [PDF]
ACS OmegaIndicator displacement assays work by detecting the replacement of an indicator from a binding site by an analyte. The binding sites are typically located on individual receptor molecules capable of carrying out molecular recognition. Here, we describe a new transduction mechanism based on analyte partitioning in a two-phase system, which we refer to ...

An indicator displacement assay with independent dual wavelength emission. [PDF]
Tetrahedron Lett, 2010 A multifunctional metallo-receptor was designed with both metal and boronic acid binding groups. A sensor ensemble was prepared using the metallo-receptor and the fluorescent dye ARS. The dye produced two distinct fluorescent bands from interaction with the boronic acid and the metal respectively.
