Determination of fipronil and its metabolites in edible oil by pollen based solid-phase extraction combined with gas chromatography-electron capture detection

Comprehensive study of allergenic tree species: Palynological insights enhanced by HPLC and GC–MS profiling

“…These methods reveal the diverse textures, apertures, and ornamentations present on pollen surfaces, aiding in species identification and deepening our understanding of how pollen interacts with the environment. SEM in conjunction with chromatography allows researchers to explore the correlation between the structural characteristics of pollen grains and their chemical constituents (Zhou et al, 2022). This approach enables the exploration of potential functional relationships between pollen surface characteristics and the presence of specific biomolecules, within the context of developmental and evolutionary significance.…”

Colorimetric and ratiometric supramolecular AIE fluorescent probe for the on-site monitoring of fipronil

“…However, they are seriously limited in practice by certain shortcomings, including complicated operations that are also costly, and time and labor-intensive. [10][11][12] In comparison, fluorescent analytical methods have demonstrated great superiorities in health analysis and environment detection through their several advantages, such as ease of use, rapid response, high sensitivity, and good selectivity. [13][14][15] To date, some fluorescent analytical methods have been successfully applied for FPN detection, including the use of fluorescent aptamers, covalent-organic frameworks, and lanthanide-coordinated polymers.…”

Bifunctional Amine- and Thiol-Modified Ti3C2Tx MXene for Trace Detection of Heavy Metals

“…Among different heavy elements, cadmium, lead, and inorganic arsenic are critical because of their association with numerous health issues, including impaired brain development in children, cardiovascular diseases, cancer, , kidney malfunctions, and various neurological impacts that are still under investigation. , While there are efforts to reduce the release of these elements, which is primarily due to human activities such as farming and industrial processing, , it is equally important to know how much exposure humans receive through the consumption of food and water. Several analytical methods, including solid-phase extraction (SPE), − have been developed to determine the content of heavy metals, which are generally present at trace levels in real-life samples. − One of the SPE family members is dispersive micro solid-phase extraction (d-μ-SPE), ,− which benefits from both high dispersions of the solid phase for better extraction and the utilization of the solid phase in the “microgram” regime.…”
