“…However, it has proven to be a threat to human health. In fact, nitrite is an essential precursor of carcinogenic N -nitrosamines, which can result in serious health issues even at very low concentrations [ 62 , 63 ]. Furthermore, nitrite can interfere with the oxygen transport system and may result in methaemoglobinaemia, which can cause tissue hypoxia and, possibly, death [ 59 , 63 ].…”

Lately, scandals associated with the illegal addition of poisonous chemicals to food for commercial interests have been gradually disclosed to the public. Problems related to food safety do not only harm public health but also affect the stability of economic and social development. Food safety has become a common issue in society, and strengthening the related regulations have become increasingly important. Although conventional techniques are accurate and sensitive in the detection of the vast majority of illegal food additives, they rely on time-consuming, labor-intensive procedures that depend on expensive instruments. Thus, efficient and rapid identification of poisonous, illegal additives in food is a crucial task in analytical chemistry. Recently, in this context, gold nanoparticles (GNPs) have attracted considerable attention because of their optical, electronic, catalytic, and chemical properties. Their excellent properties have facilitated the widespread use of GNPs in different sensors. This review covers the two most common GNP-based sensors with colorimetric and electrochemical responses, which have proven to be effective in the detection of illegal additives. The GNP-based sensors comply with the requirement of modern analysis, such as high selectivity, sensitivity, simplicity, rapidity, and portability. Thus, they have great potential as powerful sensing tools for food safety screening. This review elucidates the utility and advances of GNP-based colorimetric and electrochemical sensors for the detection of illegal additives in the food industry and in the supervision of food quality and safety. Additionally, an outlook of the trends and future development of research on these sensors is provided.

“…Few studies investigated the treatment of NDEA in drinking water and wastewater streams connected with carbon capture. [19,20] Reverse osmosis and treatment using direct UV light were employed in the treatment of NDEA and NDMA. [21] Fenton mechanism for the decomposition of NDMA and NDEA was also employed with emphasis on the nitric oxide formation.…”

This study reports the synthesis and characterization of tungsten trioxide‐based catalysts for the photocatalytic degradation of N‐nitrosodiethylamine (NDEA) in wastewater. Tungsten trioxide (WO3) was synthesized using the thermal treatment method (TTM) and hard template replication method (HTRM) and impregnated with lanthanum (La), iron (Fe), chromium (Cr), and silver (Ag) to enhance its light absorption ability. The synthesized catalysts were characterized using various techniques, including UV‐Vis spectroscopy, Brunauer–Emmett–Teller (BET), Barrett–Joyner surface area and porosity, X‐ray diffraction (XRD), and thermogravimetric analysis (TGA). The experimental design approach used a response surface methodology (RSM) with a face‐centered central composite design (FCCCD) technique. Catalyst loading (%), pH of solution, and catalyst concentration (g/L) were chosen as design factors, with the response variable being NDEA degradation efficiency (%). The obtained data were analyzed, and a quadratic model was chosen as the best fit with statistically significant model terms as observed from the analysis of variance (ANOVA). 3D interaction plots were generated to explain the effect of the various interaction terms of the quadratic model. The results showed that the pH of the solution was the major factor affecting NDEA degradation efficiency. The mean degradation efficiency of NDEA was 93.03% for Fe/WO3, 88.90% for Ag/WO3, 86.48% for La/WO3, and 84.03% for Cr/WO3. These findings demonstrate the potential of tungsten trioxide‐based catalysts impregnated with various metals for the effective treatment of NDEA in wastewater through heterogeneous photocatalysis.

The current study deals with the effect of N-Diethylnitrosamine (DEN) induced traumatic brain injury on male albino rats, as well as the outcome results of treatment with paclitaxel nanoparticles for a period of 8 weeks with two-week intervals is the concern of the present study. Mean body weight, as well as brain weight, was considered as the main parameters whereas a detailed immunohistochemical study on rat brain sections was performed. Astrocytic biomarkers for the diagnosis of astrocytes by fibrillary glial acidic protein (GFAP). Neuronal GFAP staining used for various broke sections were forwarded. Comparison and Contrast of all these parameters in all steps of the experiment had been discussed. The efficiency of the treatment was found to be evident. The effect on body weight was significant whereas brain weight results showed insignificant differences. A longer duration of treatment may well reflect more significant results.
