Solid-phase colorimetric sensor for hypochlorite

The Analyst, 2021
By taking advantage of the powerful oxidation property of hypochlorite (OCl−), we developed a solid-phase colorimetric sensor for the detection of OCl− based on 13 nm AuNPs immobilized on a 3-aminopropyltriethoxysilane APTES-coated substrate.

A colorimetric sensor array for the discrimination of glucosinolates

Food Chemistry, 2020
A novel approach for the discrimination of different glucosinolates (sinigrin, progoitrin, gluconapin, 4-methoxyglucobrassicin, glucoraphanin, glucobrassicin, glucoiberin, glucobrassicanapin, glucoraphenin, and glucoerucin) using a colorimetric sensor array (CSA) is reported herein.

Fabrication of a Colorimetric Electrochemiluminescence Sensor

Analytical Chemistry, 2008
A colorimetric electrochemiluminescence (ECL) sensor was fabricated for the first time, based on a dual-color system including a strong red Ru(bpy)(3)(2+) ECL and a green reference light from a light emitting diode. Traditional ECL intensity information can be easily transformed into a color variation with this sensor, and the color variation can be ...

Colorimetric Polymethacrylate Sensor

Advanced Materials Research, 2014
The paper describes a new colorimetric sensor. The colorimetric sensors were made of optically transparent polymethacrylate matrix with physically immobilized analytical reagent which is responsible for the extraction of the analyte into the sensing material and changing its color.

A Colorimetric Sensor Array for Organics in Water

Journal of the American Chemical Society, 2005
Molecular recognition of organic compounds in aqueous solutions is inherently challenging due to the potential interference from the very high concentration of water. Here we present a simple colorimetric sensor array that probes a wide range of chemical properties.
