Selective and sensitive colorimetric detection of endocrine disrupter fungicide carbendazim through secnidazole capped silver nanoparticles.

Pesticides and fungicides are extremely useful to hinder the attacks of pests and fungi to secure crops, vegetables, fruits and other plants but due to their endocrine disrupting and carcinogenic risks in humans and animals through their continued addition in water resources they are extremely important to monitor carefully. In this investigation we synthesized silver nanoparticles (AgNPs) via the reducing action of sodium borohydride in the presence of secnidazole (SEC) as capping agent under various optimized parameters such as the concentration of NaBH, silver nitrate (AgNO), SEC and pH. These SEC-AgNPs were characterized through various techniques including ultra-violet visible (UV-Vis) spectroscopy, Fourier transform infra-red (FTIR) spectroscopy, field emission scanning electron microscopy (FESEM), atomic force microscopy (AFM), dynamic light scattering (DLS) and zeta-potential analysis (ZPA) in order to investigate their diverse properties.

Characterization of Ibu-HgNPs was carried out by UV-Vis spectrophotometry and transmission electron microscopy (TEM). The prepared Ibu-HgNPs were immobilized onto a glassy carbon electrode (GCE) and used for the first time as the sensing element for voltammetric determination of low concentrations of acrylamide (AA) in aqueous solutions.

Effect of green and chemically synthesized titanium dioxide nanoparticles on cadmium accumulation in wheat grains and potential dietary health risk: A field investigation.

A field study was designed to explore the impacts of foliar-applied chemically and green synthesized titanium dioxide nanoparticles (TiO NPs) on cadmium (Cd) uptake in wheat plants.
