Characterization of magnetic Fe3O4@SiO2 nanoparticles with fluorescent properties for potential multipurpose imaging and theranostic applications

Influence of NIR Laser and Alternating Magnetic Field on Core-Shell Nanoparticles for Cell Lines Treatment

“…These results are consistent with those of Maximenko et al[21]. The XRD pattern of the Fe 3 O 4 -Au @SiO 2 CSNPs is identical to the pattern of Fe 3 O 4 @Au NPs, with the exception of the broad peak at 2θ=15-25, which is due to the amorphous SiO 2[22]. This implies that theSiO 2 shell around Fe 3 O 4 -Au has no effect on the initial stucture of Fe 3 O 4 -Au due to its good protective function.…”

Nanomagnetic macrocyclic Schiff-base–Mn(ii) complex: an efficient heterogeneous catalyst for click approach synthesis of novel β-substitued-1,2,3-triazoles

“…The FT-IR of the synthesized [Fe 3 O 4 @PAM–Schiff base–Mn][ClO 4 ] shows new absorption bands at 1590–1615 cm −1 which are related to the C N bonds confirming the generation of Mn-coordinated Schiff base complex. 88 …”

Hercynite silica sulfuric acid: a novel inorganic sulfurous solid acid catalyst for one-pot cascade organic transformations

“… 55 Moreover, the XRD pattern of hercynite@SiO 2 represents that besides the all-diffraction peaks of nano hercynite, the position of a broad peak which appeared at 2 θ = 18–29° is due to the short-range order structure. 56 Besides, it also discloses the presence of an amorphous phase of silica nano-phase segments, which generally occurs due to the surface stabilized SiO 2 shell indicating that the surface of magnetic core–shell particles is amorphous in structure. The P-XRD pattern of hercynite@SSA represents that, after adding the SO 3 H functionalities, some new peaks appeared at 2 θ = 22–30° confirming the successful surface functionalization by acidic species.…”
