Nanoparticle‐based Indicator‐Displacement Assay for Pyrophosphate
Chemistry – An Asian Journal, 2011AbstractSilica nanoparticles functionalized with a ZnII‐dipicolylamine derivative are used as the receptor component of a sensing ensemble for an indicator‐displacement assay. The nano‐ensemble system, constructed with pyrocatechol violet as an indicator, selectively senses pyrophosphate over other anions including hydrogen phosphate, thus showing a ...

Intramolecular Indicator Displacement Assay for Anions: Supramolecular Sensor for Glyphosate
Journal of the American Chemical Society, 2014One of the well-known strategies for anion sensing is an indicator (dye) displacement assay. However, the disadvantage of the dye displacement assays is the low sensitivity due to the excess of the dye used. To overcome this setback, we have developed an "Intramolecular Indicator Displacement Assay (IIDA)".

Dinuclear zinc complex for fluorescent indicator-displacement assay of citrate
Sensors and Actuators B: Chemical, 2015Abstract Two zinc complexes based on 9,10-distyrylanthracene, 1-Zn and 2-Zn, were synthesized for fluorescence indicator-displacement assay of citrate. The fluorescence of the two complexes can be quenched significantly by energy transfer mechanism upon the binding of a common indicator – phenol red (PR). By using the chemo-ensemble of 2-Zn and PR, a

Colorimetric sensing of anions in water using ratiometric indicator-displacement assay
Analytica Chimica Acta, 2012The analysis of anions in water presents a difficult challenge due to their low charge-to-radius ratio, and the ability to discriminate among similar anions often remains problematic. The use of a 3×6 ratiometric indicator-displacement assay (RIDA) array for the colorimetric detection and identification of ten anions in water is reported.

A sulphide selective colorimetric metal complexing indicator-displacement assay has been developed using an immobilized copper(II) complex of the azo dye 1-(2-pyridylazo)-2-naphthol printed by inkjetting on a nylon support. The change in colour measured from the image of the disposable membrane acquired by a digital camera using the H coordinate of the

Coordination Chemistry Reviews, 2006
Indicator displacement assays (IDAs) are now a popular method for converting most any synthetic receptor into an optical sensor. In this review many such assays are highlighted, along with biological counterparts. The focus is upon colorimetric, fluorescent, and metal containing IDAs.

Indicator Displacement Assays Inside Live Cells
Angewandte Chemie International Edition, 2014AbstractThe macrocyclep‐sulfonatocalix[4]arene (CX4) and the fluorescent dye lucigenin (LCG) form a stable host–guest complex, in which the dye fluorescence is quenched. Incubation of live V79 and CHO cells with the CX4/LCG chemosensing ensemble resulted in its spontaneous uptake.
