“…Additionally, peaks at 522 cm –1 and 706 cm –1 correspond to cobalt-oxygen and iron-oxygen bonds of Fe 2 O 4 , while those at 417 cm –1 and 522 cm –1 confirm vibrations from octahedral and tetrahedral sites in ternary NiCoFe 2 O 4 . Weak peaks at 1365 cm –1 and 1592 cm –1 relate to hydroxyl group vibrations from structural waters [ 66 , 82 – 84 ]. The displacement and reduction of these rosemary extract peaks yield three distinct fingerprints in the NiCoFe 2 O 4 spectrum, affirming the reduction of metal ions by rosemary extract polyphenols.…”

Multicomponent nanoparticle systems are known for their varied properties and functions, and have shown potential as gene nanocarriers. This study aims to synthesize and characterize ternary nickel–cobalt-ferrite (NiCoFe2O4) nanoparticles with the potential to serve as gene nanocarriers for cancer/gene therapy. The biogenic nanocarriers were prepared using a simple and eco-friendly method following green chemistry principles. The physicochemical properties of the nanoparticles were analyzed by X-ray diffraction, vibrating sample magnetometer, X-ray photoelectron spectroscopy, and Brunauer–Emmett–Teller. To evaluate the morphology of the nanoparticles, the field emission scanning electron microscopy with energy dispersive X-Ray spectroscopy, high-resolution transmission electron microscopy imaging, and electron tomography were conducted. Results indicate the nanoparticles have a nanoflower morphology with a mesoporous nature and a cubic spinel structure, where the rod and spherical nanoparticles became rose-like with a specific orientation. These nanoparticles were found to have minimal toxicity in human embryonic kidney 293 (HEK-293 T) cells at concentrations of 1 to 250 µg·mL–1. We also demonstrated that the nanoparticles could be used as gene nanocarriers for delivering genes to HEK-293 T cells using an external magnetic field, with optimal transfection efficiency achieved at an N/P ratio of 2.5. The study suggests that biogenic multicomponent nanocarriers show potential for safe and efficient gene delivery in cancer/gene therapy. Graphical Abstract

“…Multi-component reactions (MCRs) are a relatively new and popular method in synthetic chemistry. [1][2][3][4] These reactions involve the simultaneous interaction of three or more molecules, resulting in the formation of a new molecule with new chemical bonds. The advantages of MCRs include their simplicity, [5] speed, [6] high yield, [7] and versatility, which have contributed to their widespread use in drug development [8] and synthetic chemistry.…”

This study involves the synthesis of pyrano]2,3‐d[pyrimidine derivatives using the multi‐component reactions (MCRs) under ultrasonic, and nanocatalysis conditions. The reaction efficiency was increased and the reaction time was reduced by using a prepared catalyst accomplished with sonication synergetic effect. Furthermore, the increase in product yield can be due to the synergistic property between metals on the surface of the catalyst. This catalyst was found to be recoverable and highly stable under ultrasonic conditions. The use of trimetallic multi‐walled carbon nanotubes (MWCNTs) proved to be highly effective in synthesis of the pyrano[2,3‐d]pyrimidine derivatives. This is due to their active site, economical catalyst loading, easy workup, reusability, and green reaction conditions. Also, the synthesized products were achieved in excellent yields and short reaction times. Different methods were utilized to characterize the nanocatalyst such as; Fourier‐transform infrared spectroscopy (FT‐IR), X‐ray powder diffraction (XRD), field emission scanning electron microscope (FE‐SEM), energy‐dispersive X‐ray spectroscopy (EDS), thermogravimetric analysis (TGA), and the hot filtration method. The synthesized organic compounds were identified through analyses using the melting point, FT‐IR method, and hydrogen‐1 nuclear magnetic resonance (1H NMR).
