Guidelines for Pattern Recognition Using Differential Receptors and Indicator Displacement Assays
The Journal of Organic Chemistry, 2009A colorimetric sensor array consisting of designed receptors and metal salts was utilized for discrimination of structurally similar carboxylic acid analytes (25-31). For the discrimination, the receptors do not need to have a 1:1 guest-receptor binding stoichiometry.

Indicator displacement assays that detect bilayer membranes enriched in phosphatidylserine
Journal of Materials Chemistry, 2005Three indicator displacement assays are described for the detection of phosphatidylserine in a bilayer membrane. A series of Zn2+-dipicolylamine coordination compounds are used to bind selectively to the phosphatidylserine and act as a colorimetric chemosensing ensemble when combined with the UV-Vis indictor pyrocatechol violet.

Colorimetric Indicator Displacement Assays (CIDAs)
Owing to the unique advantages of naked eye color detection in the sensing of various important analytes, colorimetric indicator displacement assay (C-IDA) has received its recognition as the principal evolutionary extension of IDA. This chapter, besides dealing with all conceptual details of C-IDA, also offers basic criteria for the development and ...Ishfaq Ahmad Rather, Rashid Ali

Journal of the American Chemical Society, 2005
Enantioselective association events between boronic acid receptors and bifunctional substrates such as alpha-hydroxycarboxylates and vicinal diols were exploited to develop enantioselective indicator-displacement assays. It was found that the sensitivity of the assay could be tuned by using either colorimetric or fluorescent indicators.

Using Indicator-Displacement Assays in Test Strips and To Follow Reaction Kinetics
Organic Letters, 2004[structure: see text] An indicator-displacement assay was used to study the kinetics of reactions that produce tartrate. The same assay was also found to be useful in developing tartrate test strips, by coating filter paper with the same receptor and indicator.

Metal Complexing Indicator Displacement Assays (M-IDAs)
As a sub-class of colorimetric indicator displacement assays (C-IDAs) as well as fluorimetric indicator displacement assays (F-IDAs), metal indicator displacement assays (M-IDAs) involve primarily the coordination of metal ions with a target receptor and subsequent coordination of colorimetric or fluorimetric indicator with complexed metal ions and ...Ishfaq Ahmad Rather, Rashid Ali
