The Rietveld refined X-ray diffraction pattern of NiₓMn<sub>1-x</sub>Fe₂O₄ MNPs ensures the single phase with crystallite size varies from 28 to 40 nm. X-ray photoelectron spectroscopy (XPS) analysis further revealed the surface composition and oxidation states of Ni²⁺, Fe³ ⁺, and Mn²⁺ ions. The colloidal stability was demonstrated by the increased zeta potential (ζ), ranging from −59 to −22 mV, indicating stronger electrostatic repulsion between the NiₓMn<sub>1-x</sub>Fe₂O₄ MNPs. The substitution of Ni<sup>2 +</sup> ions reduces the magnetic moment, as evidenced by a decrease in saturation magnetization and an increase in coercive field. This reduction is further supported by dynamic magnetization measurements, which exhibit an increase in resonance field and a narrower peak-to-peak linewidth. These changes are attributed to the replacement of Mn²⁺ ions by Ni²⁺ ions, which suppresses the superexchange interaction between Mn²⁺-O-Fe³ ⁺ ions. Furthermore, the self-heating efficiency was evaluated through a specific absorption rate (SAR) under an alternating magnetic field of 9.5 kA/m. Among NiₓMn<sub>1-x</sub>Fe₂O₄ MNFs, the MnFe<sub>2</sub>O<sub>4</sub> achieves the highest SAR of 129 W/g at a low concentration of 1 mg/mL.

Consequently, the synthesized NiₓMn<sub>1-x</sub>Fe₂O₄ MNPs demonstrate the potential for effective cancer treatment at low concentrations (1 mg/mL) and low magnetic fields (9.5 kA/m).

Compression test results demonstrate that modified NAs possess good compression resistance and high elasticity, attributed to the inter-connected and cross-linked network structure. Brunauer-Emmett-Teller analysis demonstrates that the specific surface area and average pore diameter of these NAs decrease with increasing CS content, leading to a more compact network structure and increased substance density. In dye adsorption experiments, various pH values, temperatures, contact times and initial concentrations are comprehensively investigated to explore the adsorption mechanism. Adsorption results are well fitted using the pseudo-second-order kinetics, Langmuir isotherm and Elovich models because of the adsorption mechanism being of chemisorption type.
