Luminescent Chemosensors Based on Silica Nanoparticles
2010The field of nanoparticles is amazingly many-sided and consequently their applications range between many different areas from industry to bio-analysis and catalysis. In particular, luminescent nanoparticles attract close attention in the areas of biology, medical diagnosis and therapy, where they already find many applications.

A Chemosensor for Citrate in Beverages
Angewandte Chemie International Edition, 1998Competitive binding like that in immunoassays is the principle behind the chemosensor based on receptor 1, which was used to measure the concentration of citrate (2) in a series of common beverages. Citrate displaces the fluorescent colorimetric probe 5-carboxylfluorescein (3) from 1, and the process can be monitored by UV or fluorescence spectroscopy.

New ionochromic azomethinimine chemosensors
Russian Chemical Bulletin, 2015A reaction of 5-phenylpyrazolidin-3-one with hydroxy-substituted aromatic aldehydes led to azomethinimines, the representatives of a new class of chemosensors exhibiting ionochromic properties. Electron spectroscopy was used to identify efficient chemosensors toward Cu2+ cations and F– anions.

Phenanthroline-Derived Ratiometric Chemosensor for Ureas
The Journal of Organic Chemistry, 2007The syntheses of 1,10-phenanthroline fluorophore-based chemosensor 7 and its truncated analog 9 are reported. Interactions of these compounds with urea, thiourea, 1,3-dimethylurea, tetrahydropyrimidin-2(1H)-one, imidazolidin-2-one, and selected uronium salts were assessed by three-dimensional excitation-emission spectroscopy, UV-vis absorbance, and ...

Carbazole incorporated ratiometric chemosensor for Zn2+
Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 2013An electron donating carbazole incorporated thiazole (3) based Zn(2+) selective intrinsic chemosensor has been synthesized and investigated. It was found that electron donating substituents such as methyl and carbazole on chemosensor (1) produce remarkable red shift in emission upon complexation with Zn(2+).

Click Triazoles as Chemosensors
2012The "click" generation of a 1,4-disubstituted triazole from a terminal alkyne and a terminal azide has been widely used in recent years to prepare a plethora of sensor systems for the detection of cations, anions, small molecules and biomolecules. The focus of the chapter is on sensors in which the triazole plays an intimate role in the sensing event ...
