Hemoglobin detection using curcumin nanoparticles as a colorimetric chemosensor
This article presents a simple and efficient measurement system for quantitative sensing of blood hemoglobin (Hgb) using curcumin nanoparticles (CURNs). The Hgb monitoring is based on CURNs aggregation in the presence of Hgb, which leads to a decrease in the absorption intensity of CURNs. In this study the analytical signal for the measurement of blood Hgb concentration was defined as the diffe...
متن کاملPentiptycene-Derived Fluorescence Turn-Off Polymer Chemosensor for Copper(II) Cation with High Selectivity and Sensitivity
Fluorescent conjugated polymers (FCPs) have been explored for selective detection of metal cations with ultra-sensitivity in environmental and biological systems. Herein, a new FCP sensor, tmeda-PPpETE (poly[(pentiptycene ethynylene)-alt-(thienylene ethynylene)] with a N,N,N′-trimethylethylenediamino receptor), has been designed and synthesized via Sonogashira cross-coupling reaction with the g...
متن کاملA colorimetric and fluorometric dual-modal supramolecular chemosensor and its application for HSA detection.
A colorimetric and fluorometric dual-modal supramolecular chemosensor has been fabricated by using the H- and J-aggregates of a cyanine dye, which has been successfully applied to detect human serum albumin (HSA) in urine with high specificity.
متن کاملA highly efficient dinuclear Cu(II) chemosensor for colorimetric and fluorescent detection of cyanide in water.
A novel dinuclear copper chemosensor selectively binds cyanide over a wide range of inorganic anions, enabling it to detect cyanide in water up to 0.02 ppm which is 10 times lower than the EPA standard for drinking water.
متن کاملSpiropyran as a reusable chemosensor for selective colorimetric detection of aromatic thiols.
Design of optical molecular probes for selective detection of aromatic thiols has attracted much attention. Although several types of probes have been proposed, all of them exhibit colorimetric or fluorometric response via irreversible reaction with aromatic thiols and cannot be reused. Here we report that a spiropyran dye is the first example of a reusable chemosensor for aromatic thiols. A co...
