Abstract
The current literature mostly contains relatively vague descriptions of techniques for implementing in vitro magnetic targeting delivery of iron oxide nanoparticles (IONPs), leading to irreproducible processes and incomparable findings. This discrepancy often arises from the varying exposure of IONPs to the non-uniform magnetic field and differences in the concentration of the polymer-coated IONPs. Hence, we meticulously designed and built a system comprising a platform constructed from polyoxymethylene sheets, which securely holds the permanent magnets, and the cell culture plate. We also tailored the preparation process of the IONPs and the in vitro toxicity studies. The inherent characteristics of IONPs are further enhanced by their coating with natural polymers, alginate (Alg) and chitosan (CS).•The design and construction of the platform were carried out using a laser engraving/cutting machine along with graphic design software. The precise locations of the permanent magnets relative to the cell culture plate were determined via a Gaussmeter.•The quantities of the components in the formulation and the method for fabricating the CS/Alg-coated IONPs (CS/Alg-IONPs) were optimized to ensure that the desired physicochemical properties were obtained.•The cultivation and cytotoxicity evaluation of the fabricated CS/Alg-IONPs against MCF-7 breast cancer cells were described.
