“…Pandey et al found that the ns LAL of commercial Fe 2 O 3 powders in doubly distilled water improved the hematite particle crystallinity and increased M s from 0.024 to 3.41 emu/g [ 15 ]. Svetlichnyi et al found that the H c of the FeO x (Fe, Fe 2 O 3 and Fe 3 O 4 ) nanoparticles synthesized by ns LAL of Fe in water increased from 144 Oe to 370 Oe when the measurement temperature was reduced from 300 K to 77 K [ 16 ]. Ismail et al showed that the M s values of 16.3–20.3 emu/g for the magnetic iron oxide (Fe 3 O 4 , α-Fe 2 O 3 , FeO and ε-Fe 2 O 3 ) nanoparticles synthesized by ns LAL in SDS aqueous solution were larger than 13.8–16.2 emu/g for FeO x (Fe 3 O 4 , α-Fe 2 O 3 , ε-Fe 2 O 3 ) particles synthesized by ns LAL in dimethylformamide (DMF) at the same laser energies [ 17 ].…”

There are few reports on zero-field-cooled (ZFC) magnetization measurements for Fe@FeOx or FeOx particles synthesized by laser ablation in liquids (LAL) of Fe, and the minimum blocking temperature (TB) of 120 K reported so far is still much higher than those of their counterparts synthesized by chemical methods. In this work, the minimum blocking temperature was lowered to 52 K for 4–5 nm α-Fe2O3 particles synthesized by femtosecond laser ablation of Fe in acetone. The effective magnetic anisotropy energy density (Keff) is calculated to be 2.7–5.4 × 105 J/m3, further extending the Keff values for smaller hematite particles synthesized by different methods. Large amorphous-Fe@α-Fe2O3 and amorphous-Fe@C particles of 10–100 nm in diameter display a soft magnetic behavior with saturation magnetization (Ms) and coercivities (Hc) values of 72.5 emu/g and 160 Oe at 5 K and 61.9 emu/g and 70 Oe at 300 K, respectively, which mainly stem from the magnetism of amorphous Fe cores. Generally, the nanoparticles obtained by LAL are either amorphous or polycrystalline, seldom in a single-crystalline state. This work also demonstrates the possibility of synthesizing single-crystalline α-Fe2O3 hematite crystals of several nanometers with (104), (113), (116) or (214) crystallographic orientations, which were produced simultaneously with other products including carbon encapsulated amorphous Fe (a-Fe@C) and Fe@FeOx core-shell particles by LAL in one step. Finally, the formation mechanisms for these nanomaterials are proposed and the key factors in series events of LAL are discussed.

“…The synthesis of complex structures like core-shell MNPs with laser ablation is possible with a broad degree of freedom to control the variations of the material, target, environment, laser regime, and external stimulatory signals (Xiao et al, 2017). Other advantages include the lack of requirement for high pressure, temperature, or organometallic precursors to generate MNPs with high magnetic specification (Svetlichnyi et al, 2017). Therefore, the laser ablation technique is promising for the setting of higher standards in the synthesis of nanomaterials.…”

Liver fibrosis is a major cause of morbidity and mortality worldwide due to chronic liver damage and leading to cirrhosis, liver cancer, and liver failure. To date, there is no effective and specific therapy for patients with hepatic fibrosis. As a result of their various advantages such as biocompatibility, imaging contrast ability, improved tissue penetration, and superparamagnetic properties, magnetic nanoparticles have a great potential for diagnosis and therapy in various liver diseases including fibrosis. In this review, we focus on the molecular mechanisms and important factors for hepatic fibrosis and on potential magnetic nanoparticles-based therapeutics. New strategies for the diagnosis of liver fibrosis are also discussed, with a summary of the challenges and perspectives in the translational application of magnetic nanoparticles from bench to bedside.

Recently, magnetic nanomaterials have emerged as multifunctional materials for a wide range of biomedical applications. Functional magnetic iron oxide nanoparticles (FMIONs) are typical magnetic nanomaterials with inherent advantages for disease diagnosis, prevention, and treatment: high specific surface area, excellent superparamagnetism, good colloidal stability, and remarkable biosafety. Therefore, FMION‐based biomedicine has advanced at an unprecedented rate in recent years. However, the performance of FMIONs cannot yet meet complicated physiological circumstances. To overcome these limitations, researchers have designed and manipulated the geometric shapes, sizes, compositions, and surfaces to endow these FMIONs with high performance. This review summarizes recent advances in the controlled synthesis of FMIONs, cover corresponding theories of nucleation and growth in solution, and the tuning of FMION properties for disease diagnosis and therapy. After discussing the biomedical applications in cancer theranostics—tumor hyperthermia, magnetic resonance imaging and drug delivery system—in detail, the review concludes with current challenges and outlooks for the development of FMIONs.
