A review on magnetic sensors for monitoring of hazardous pollutants in water resources

Biosynthesis of iron oxide nanoparticles for the degradation of methylene blue dye, sulfisoxazole antibiotic and removal of bacteria from real water

“…For ion exchange, the pre-treatment of all the samples is always a requirement and for biological methods, standardization is required and in most cases, these methods have a poor efficiency. Of these methods, photocatalysis is the most preferred method by researchers as it has been shown to degrade complex pollutants, is easy to use and can produce reproducible results [ 9 , 10 , 11 ].…”

“…Synthesis strategies such as sol gel, chemical vapour deposition and pyrolysis have been found to promote the usage of unsafe, hazardous solvents and with synthesis conditions requiring extremely high pressures and temperatures. Furthermore, they generate a large surface ratio and higher energy levels on the surface of the material [ 11 , 12 ]. Moreover, the chemical synthesis methods tend to affect the iron-based nanoparticles by reducing their magnetic properties.…”

Advanced microplastic monitoring using Raman spectroscopy with a combination of nanostructure-based substrates

“…Consequently, a series of studies on the chronic toxicity of MNP exposure has reported on potential risks that may be linked to various human health issues, including endocrine disturbances, reproductive toxicity [ 32 ], neurotoxicity, gastrointestinal toxicity, liver toxicity [ 14 ], cardiac fibrosis [ 33 ], pulmonary fibrosis, and even carcinogenesis [ 10 ]. Additionally, a line of proof has emerged of negative effects from exposure to PS MNPs and additives for blood plasma [ 34 , 35 ] and human health [ 36 ].…”

Electrochemical detection of folic acid using a modified screen printed electrode

“…These methods are time-consuming, expensive and require complicated pre-treatment steps. On the other hand, the electrochemical methods are a very promising way for the determination of folic acid and other compounds due to easy fabrication, low cost and rapid analysis compared to other analytical methods [15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30].…”
