Abstract
Aim: This report proposes using the Hill model to assess the benchmark dose, the 50% lethal dose, the cooperativity and the dissociation constant while analyzing cell viability data using nanomaterials to evaluate the antitumor potential while combined with radiofrequency therapy. Materials & methods: A nanocomposite was synthesized (graphene oxide-polyethyleneimine-gold) and the viability was evaluated using two tumor cell lines, namely LLC-WRC-256 and B16-F10. Results: Our findings demonstrated that while the nanocomposite is biocompatible against the LLC-WRC-256 and B16-F10 cancer cell lines in the absence of radiofrequency, the application of radiofrequency enhances the cell toxicity by orders of magnitude. Conclusion: This result points to prospective studies with the tested cell lines using tumor animal models.

Abstract
Conventional magnetic nanoagents in cancer hyperthermia therapy suffer from a low magnetic heating efficiency. To address this issue, researchers have pursued magnetic nanoparticles with topological magnetic domain structures, such as the vortex-domain structure, to enhance the magnetic heating performance of conventional nanoparticles while maintaining excellent biocompatibility. In this study, we synthesized hollow spherical Mn0.5Zn0.5Fe2O4 (MZF-HS) nanoparticles using a straightforward solvothermal method, yielding samples with an average outer diameter of approximately 350 nm and an average inner diameter of about 220 nm. The heating efficiency of the nanoparticles was experimentally verified, and the specific absorption rate (SAR) value of the hollow MZF was found to be approximately 1.5 times that of solid MZF. The enhanced heating performance is attributed to the vortex states in the hollow MZF structure as validated with micromagnetic simulation studies. In vitro studies demonstrated the lower cell viability of breast cancer cells (MCF-7, BT549, and 4T1) after MHT in the presence of MZF-HS. The synthesized MZF caused 51% cell death after MHT, while samples of MZF-HS resulted in 77% cell death. Our findings reveal that magnetic particles with a vortex state demonstrate superior heating efficiency, highlighting the potential of hollow spherical particles as effective heat generators for MHT applications.

Abstract
A Ga3+-substituted spinel magnetite nanoparticles (NPs) with the formula Ga0.9Fe2.1O4 were synthesized using both the one-pot solvothermal decomposition method (TD) and the microwave-assisted heating method (MW). Stable colloidal solutions were obtained by using triethylene glycol, which served as a NPs stabilizer and as a reaction medium in both methods. A narrow size distribution of NPs, below 10 nm, was achieved through selected nucleation and growth. The composition, structure, morphology, and magnetic properties of the NPs were investigated using FTIR spectroscopy, thermal analysis (TA), X-ray diffraction (XRD), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), and magnetic measurements. NPs with the expected spinel structure were obtained in the case of the TD method, while the MW method produced, additionally, an important amount of gallium suboxide. The NPs, especially those prepared by TD, have superparamagnetic behavior with 2.02 μB/f.u. at 300 K and 3.06 μB/f.u. at 4.2 K. For the MW sample these values are 0.5 μB/f.u. and 0.6 μB/f.u. at 300 K and 4.2 K, respectively. The MW prepared sample contains a secondary phase and very small NPs which affects both the dimensional distribution and the magnetic behavior of NPs. The NPs were tested in vitro on amniotic mesenchymal stem cells. It was shown that the cellular metabolism is active in the presence of Ga0.9Fe2.1O4 NPs and preserves an active biocompatible cytoskeleton.

Abstract
Ferroptosis therapy by catalyzing the Fenton reaction has emerged as a promising tumor elimination strategy for lung adenocarcinoma (ADC). However, the unsatisfactory Fenton reaction efficiency, strong intracellular antioxidant system, and insufficient lung drug accumulation limits the ferroptosis therapeutic effect. To address these issues, an inhalable nanoreactor was proposed by spontaneously adsorbing biomimetic protein corona (PC) composed of matrix metalloproteinase 2 responsive gelatin and glutamate (Glu) on the surface of cationic nanostructured lipid carriers (NLC) core loaded with ferrocene (Fc) and fluvastatin. The prepared Fc-NLC(F)@PC could be nebulized into lung lesions with 2.6 times higher drug accumulation and boost lipid peroxide production by 3.2 times to enhance ferroptosis therapy. Mechanically, fluvastatin was proved to inhibit monocarboxylic acid transporter 4 mediated lactate efflux, inducing tumor acidosis to boost Fc-catalyzing reactive oxygen species production, while the extracellular elevating Glu concentration was found to inhibit xCT (system Xc-) functions and further collapse the tumor antioxidant system by glutathione synthesis suppression. Mitochondrial dysfunction and cell membrane damage were involved in the nanoreactor-driven ferroptotic cell death process. The enhanced antitumor effects by combination of tumor acidosis and antioxidant system collapse were confirmed in an orthotopic lung ADC tumor model. Overall, the proposed nanoreactor highlights the pulmonary delivery approach for local lung ADC treatment and underscores the great potential of ferroptosis therapy.
