An on-site, sensitive, and cost-effective method for determining aflatoxin B1 (AFB1) in rice samples is proposed, combining magnetic solid phase extraction (MSPE) and time-resolved fluorescence immunochromatography (TRFICA) techniques. Cost-effective rice husks were carbonized and combined with nanomaterials to make magnetic nanocomposites that acted as effective adsorbents in MSPE. Under optimal conditions, the entire process was completed in 15 min with a visual detection limit of 0.

Here, a high molecular weight polysaccharide preparation from Ophiocordyceps gracilis was utilized as a stabilizer and dispersant to create nanocomposites based on selenium nanoparticles (GSP-1a-SeNPs). The NPs showed the highest stability at a selenium/polysaccharide mass ratio of 1:1, with no significant change after 28 days of storage at 4 °C. The NPs exhibited a symmetrical spheroid structure with an average diameter of 85.

In recent years, attempts were made to develop biomaterials using synthetic and natural polymers to induce osteogenesis of human mesenchymal stem cells (hMSCs). Poly(ε-caprolactone) (PCL) is one of the few synthetic polymers with the potential to differentiate hMSCs to bone. However, its potential is limited, attributed to its low strength; its fast crystallization rate also compromises its dimensional stability.

This work presents a convenient and easy-to-operate method for synthesizing the functionally integrated nanocomposite of nitrogen-doped multi walled carbon nanotube networks (N-CNTs) and cobalt 2-methylimidazole (ZIF-67) nanoparticles. The N-CNTs@ZIF-67 nanocomposite was utilized to design a novel electrochemical sensing platform for detecting gallic acid (GA). The N-CNTs@ZIF-67 modified glass carbon electrode (GCE) demonstrated high sensitivity for GA electrochemical detection (LOD: 10.

Wastewater is commonly contaminated with many pharmaceutical pollutants, so an efficient purification method is required for their removal from wastewater. In this regard, an innovative tertiary Se/SnO@CMC/Fe-GA nanocomposite was synthesized through encapsulation of metal organic frameworks (Fe-glutaric acid) onto Se/SnO-embedded-sodium carboxy methyl cellulose matrix to thoroughly evaluate its effectiveness for adsorption of levofloxacin drug from wastewater. The prepared Se/SnO@CMC/Fe-GA nanocomposite was analyzed via UV-Vis spectroscopy, Fourier-transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), thermo gravimetric analysis (TGA), energy dispersive X-ray (EDX), and X-ray diffraction (XRD) to valuate optical property, size, morphology, thermal stability, and chemical composition.
