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...
