Hydrazone-derived PET/CHEF fluorescent probes for sensitive detection of cesium and strontium in real samples.

In this study, two hydrazone-based probes, NSP ((E)-5-(diethylamino)-2-((2-(2,4-dinitrophenyl)hydrazineylidene)methyl)phenol) and NFH ((E)-N'-(4-(diethylamino)-2-hydroxybenzylidene)furan-2-carbohydrazide), were developed and synthesized for the specific detection of Cs+ and Sr2+ ions, respectively. Both probes were ver...

Cost-effective smartphone-integrated colorimetric sensor for the detection of ethion using gold nanoparticles

Gold nanoparticles capped with citrate were prepared and characterized using particle size measurements, FT-IR, and an HR-TEM study. The prepared particles were evaluated for their ability to detect pesticides in water samples. A color change visible to the naked eye was witnessed in a solution containing ethion. Other...
