|
Metal-organic frameworks (MOFs) are hybrid materials composed of both organic and inorganic elements. MOF materials, because of their unique structures and properties, such as controllable pore size, large surface area, excellent catalytic activity, and high density of active sites, are applied in electrochemical sensors systems for the sensitive, quick, and low-cost detection of multiple analytes |

Essay | Explain the key features of the developed procedure for monitoring pesticides in green leafy vegetables and how it addresses the challenges associated with pesticide analysis.
|
Nowadays pesticide residues in agricultural products have become an important challenge and a serious threat to human food security and health. Reduction of pesticides residues should be taken into consideration by public health authorities because of environmental and health problems. The harmful effects of pesticides in humans have included cancer, congenital anomalies, heart disease, Parkinson’s disease and Alzheimer’s disease |
