چکیده

Using the self-assembly of aromatic boronic acids with Alizarin Red S (ARS), we developed a new chemosensor for the selective detection of peroxynitrite. Phenylboronic acid (PBA), benzoboroxole (BBA) and 2-(N,N-dimethylaminomethyl)phenylboronic acid (NBA) were employed to bind with ARS to form the complex probes. In particular, the ARS-NBA system with a high binding affinity can preferably react with peroxynitrite over hydrogen peroxide and other ROS/RNS due to the protection of the boron via the solvent-insertion B-N interaction. Our simple system produces a visible colorimetric change and on-off fluorescence response towards peroxynitrite. By coupling a chemical reaction that leads to an indicator displacement, we have developed a new sensing strategy, referred to herein as RIA (Reaction-based Indicator displacement Assay).

A Dual colorimetric and Fluorometric Anion Sensor Based on Polymerizable 1, 8-Naphthalimide Dye

A new polymerizable fluorescent sensor based on the photoinduced electron transfer PET for the selective determination of fluoride ions in DMF solutions has been synthesized. The sensing system was prepared by incorporating 4-Amino-1,8-naphthalimide derivatives containing thiourea side chain at the amino moiety AFTN as a neutral F- selective flourophore and was characterized by use of the DSC, ...

An indicator-displacement assay for naked-eye detection and quantification of histidine in human urine.

A simple and efficient colorimetric method for the naked-eye detection and quantification of histidine in biological fluids was developed based on an indicator-displacement assay (IDA) and the Ni(2+)-histidine affinity pair. In this IDA approach, a commercially available dye, murexide, was used as the indicator and the selective detection of histidine was achieved based on the competition betwe...

New Usage of a Fluorometric Method to Assay Antioxidant Activity in Plant Extracts

      In the present study, an oxidative conversion of non-fluorescent dichlorofluoroscein (LDCF) to fluorescent dichlorofluoroscein (DCF) was used for detection of antioxidant properties of plant extracts. The rate of the reaction was followed by monitoring the formation of DCF as a function of time. The antioxidant assay was carried out for different concentrations of gallic acid, Salvia ...

A selective colorimetric and fluorometric ammonium ion sensor based on the H-aggregation of an aza-BODIPY with fused pyrazine rings.

The synthesis of a novel aza-BODIPY dye functionalized with fused pyrazine rings, suitable for use as a selective colorimetric and fluorometric sensor for NH(4)(+), is outlined. In addition to significant fluorescence quenching, an obvious colorimetric change from green to red-pink is observed enabling facile "naked-eye" detection of NH(4)(+).
