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
