Solid-phase colorimetric sensor for hypochlorite
The Analyst, 2021By 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.

Colorimetric Polymethacrylate Sensor
Advanced Materials Research, 2014The 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, 2005Molecular 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.

Colorimetric Sensor for ATP in Aqueous Solution
Organic Letters, 2007A new chromogenic complex 1.Zn has been synthesized, and its interactions with different biologically important phosphates have been investigated in aqueous solution (pH approximately 7.2). A visual color change can be detected on binding of ATP to 1.Zn, whereas no such change is observed when other biologically related anions (AMP, ADP, PPi, or ...

Visible Colorimetric Fluoride Ion Sensors
Organic Letters, 2005[structure: see text] Five new urea derivative naphthalene compounds were synthesized by a reaction of 1,8-diaminonaphthalene and the corresponding isocyanates and showed a distinct color change only when treated with fluoride ions.

A colorimetric sensor array for odour visualization
Nature, 2000Array-based vapour-sensing devices are used to detect and differentiate between chemically diverse analytes. These systems--based on cross-responsive sensor elements--aim to mimic the mammalian olfactory system by producing composite responses unique to each odorant.
